Packing Controller M04 Calibration

 

 

 

 Hi, welcome to General Measure’s channel. In this video, we are going to demonstrate the M04 calibration process.

 Weighing Controller M04 stainless steel version is a multi-software functional weighing instrument with packing, bulking(continuous weighing), and liquid filling applications. The full stainless steel out-case is robust and durable.

 

M04 Front Panel

Before the calibration process, I will briefly go through the front panel of M04.

There are mainly three parts:

Display area: displays weighing data, status, and formula information.

Numeric keys: for data input and shortcut parameter selection.

Function keys:

【ZERO1】for data zeroing.

【ZERO2】in the totalization interface, it can clear all formulas and user totalization.

【M】Menu key to enter the setup parameter menu.

【ESC】Exit key to exit the current page or return to the previous page.

【ENTER】to confirm the operation. On the main page is the shortcut key for parameter setting. For different parameter setups, you can press the corresponding numeric keys.

 

M04 Calibration Process

Now let's begin calibration of M04.

There are two calibration methods for M04: weight calibration and material calibration.

Weight Calibration

Weight calibration has four steps

1. Enter the calibration
2. Set parameters

3. Zero calibration and weight calibration

4. Verify the calibration linearity

 

Let’s start operating.

Firstly, power on M04, the default login user is the operator. You can press the【0】key to switch the user. The initial login password is 000000. Then press the【M】to enter the parameter menu. The calibration can be found in the left column. Press the 【ENTER】to key in the password, and you will enter the page of the calibration scale.

Set Parameters

Then we set the unit, decimal point, division value, weight range, and other parameters, which are set according to the application. The setting values in this video are only for demonstration purposes.

Press【ENTER】to set the unit, there are g, kg, t, and lb can be used.

You can press the direction keys to switch. Here, we set the unit as g, press【ENTER】to confirm.

Get to the decimal point setting page. There are options as 0, 1, 2, 3, 4. We set the decimal point to 0. Press the【ENTER】confirm

Setting the minimum division value, we have 6 options, respectively, 1, 2, 5, 10, 20, and 50. We set the minimum division value of 1 here.

Then, set the weight range. Generally, we set it as the maximum weight of the load cell. According to the scale we use, we set the range to 10000, and press【ENTER】to confirm.

Zero Calibration and Weight Calibration

Enter the zero calibration, and make sure that there is no object on the scale. After【stable】sign outputs, press the【ENTER】to get the voltage at zero point. The upper area displays the weight that is 0. The lower area displays the voltage at zero point.

Put 200g weights on the scale. After the scale is stable, enter the weight calibration interface and input 200. The weight calibration is completed.

Verify Calibration Linearity

The current weight is 200g on the scale. Put on another 200g weight, the M04 shows 400g. Remove all weights, it displays 0g, which conforms to reality. The verification is finished, and the calibration is successful.

 

Material Calibration

If without weights or inconvenient to use weights on site, we can also carry out material calibration. The material calibration is only applicable to the hopper mode for M04.

Step 1: Make sure that the scale is empty, after【stable】sign outputs, click the digital button【1】to start calibration.

Step 2: Click【2】to open the filling gate. So you can put materials on the scale, click【2】again to close the filling gate. Click【3】to open the discharging gate, and the materials will flow out. Then click【3】to close the discharging gate.

The third step: weigh the test materials by a standard scale and record the data. Then press【M】to input the weight value recorded, and press【ENTER】to confirm.

We use 200g of weights for verification. You can see the weight data is correct. The material calibration is completed.

The Parameters Setting of weighing transmitter GMT-H2

 

 

 

In this video, Genear Measure's technician will demonstrate how the set the GMT-H2's parameters, which include zeroing, tracking zero point, and stability criterion. First, we need to understand the basic parameters which include zeroing, tracking zero point, and stability criterion. 

• Zeroing

Zeroing consists of "power-on zero range" and "clear range".

Both are within the percentage range of the maximum range.

1. Power-on zeroing: auto zeroing within the maximum weighing range

when the instrument is powered on.

2. Zeroing: manual zeroing during operation.

• Tracking the Zero Point

Zero tracking consists of "zero tracking range" and "zero tracking time". During the zero tracking time, if the weight change is within the tracking range, the weight comes to zero when the time is up.

• Stability Criterion

The stability criterion includes "stability range" and "stability time". During the stability time, if the weight change is within the stability range, we can say the result of weight is stable.

For operating steps, please check the video.

In the next video, we will show you How to set the preset point of GMT-H2. We will continue to bring videos of the latest products. Follow General Measure. See you in the next video!

The Calibration Method of GMT-H2

 

 

 

Hi, Welcome to General Measure’s channel. In this video, we are going to demonstrate the GMT-H2 calibration process. We need to set some parameters before calibration, which include unit, decimal point, division, and capacity. Please follow the application requirements. C1.1 is the unit, for demonstration, we set the unit as gram. C1.2 is the decimal point, set it as zero. C1.3 is the division, here we set it as 2. C1.4 is the capacity. According to the weighing platform, we set it as 1000. The calibration parameters setting is completed.

Zero Calibration

Enter the zero calibration, There are two ways, automatic acquisition or manual input. When using automatic acquisition, clear the scale and keep it stable without alarm or overflow. Then press ENTER to complete the calibration. When using manual input, enter the zero calibration, press OPTION to enter the millivolt input interface, enter the recorded history of zero millivolt data, and press ENTER to complete the calibration.

The Gain Calibration

Enter the gain calibration, There are also two ways, respectively, calibration with weights or theoretical value calibration. OFF means calibration with weights, and ON means theoretical value calibration. Select OFF to enter calibration with weights. Load a known weight. After the scale platform is stabilized, press ENTER to enter the weight input interface. Enter the weights, and press ENTER to complete the gain point 1 calibration. If you need to carry out multi-point calibration, continue to load a known weight. When the platform is stabilized, press ENTER into the weight input interface. Enter the total weights, and press ENTER to complete the calibration of the gain point 2. Follow this method, until the required calibration of the gain point is completed. Then return to the main page to check the weight. If there is an error in the weight, you can set the calibration correction coefficient to correct.

When using theoretical value calibration, select ON to enter the theoretical value calibration, SE indicates the load cell sensitivity. Set up it according to the sensitivity given by the load cell manufacturer. Press ENTER to confirm. CP means the capacity of the load cell. Set up according to your load cell capacity, press ENTER to complete the theoretical value calibration.

How to Remove the Limit Screws for Checkweigher

 

 

 

When you receive a checkweigher, but can not use it immediately Why? It is because the manufacturer has added the limit screws on the load cell module to protect it from damage caused by external forces. So we can see there is a small gap between the load cell and weighing platform. The load cell indenter can be rolled easily. In this case, we need to remove the limit screw before we use it. Both limit screws should be taken down properly. Once the screws have been removed the weighing platform and load cell would touch perfectly. Then, the checkweigher can work in a dynamic weighing line For more information on checkweighers, please contact General Measure.

The OFL Troubleshooting for weighing transmitter GMT-P1

 

 

 

In this article, we are going to share the weighing indicator OFL troubleshooting method.

Four main Causes for OFL:

1. Calibration error

2. Load cell install or wiring error

3. Overload or signal output below the zero point

4. Load cell or weighing indicator AD failure

 

 

Demonstrate Equipment: 

1. GMT-P1 weighing transmitter

2. A weighing platform and One 100g weight

3. A Multimeter 

 

Step 1,

First, we consider calibration error resulting in OFL, so we need to recalibrate the indicator. Enter the menu options, open the calibration menu, skip the previous decimal point, the division value, the range settings, to reach the load cell's current millivolt number display interface. If it shows the correct millivolt data, we enter the zero calibration menu, empty the weighing platform. Then, setting the gain calibration, place the weight on the weighing platform, and enter the right weight. The calibration is complete. We can move back to the menu interface to see if it has the proper weight display.

 

Step 2,

Suppose the load cell's current millivolt does not display properly. We can remove the load cell wiring from the GMT-P1’s terminals and use our multimeter to test the voltage between EX+,EX-. If the voltage cannot be measured, the AD part of the indicator has been damaged. If the voltage can be detected, move to step 3.

 

Step 3,

Remove the SIG+ and SIG- ends from the load cell wires, press on the weighing platform, meanwhile use a multimeter to measure the voltage between SIG+ and SIG- to see if the voltage is within a reasonable range (check the corresponding parameters of the load cell)

If the voltage is within the range and there is a change, we can estimate the OFL caused by overload weights or signal output below zero. If it is not within the range, we consider the AD part is damaged.

In this case, please contact your local equipment suppliers for help.

 

Step 4,

If it is not the above 3 problems, check if the loadcell gravity label is consistent with the direction of gravity, and check if the load cell wiring is correct. Or you can replace the load cell to exclude the load cell’s problem. 

 

That's all for OFL troubleshooting for GMT-P1. Don't forget to give us a like and follow us.

General Measure Weighing Transmitter GMT-H1 for Silo Weighing

 

 

 

GMT-H1 weighing transmitter is developed for managing incoming/outgoing material for silo weighing applications in concrete, asphalt mixing plants, feed, metallurgy and chemical batching industries.

 

In this video, we are going to demonstrate how to use GMT-H1 for silo weighing in managing in/out material weights.

 

Firstly, three important parameters need to be set, which are min in WT, min out WT, and in/out time delay. Entering the application settings, there is an IN/OUT materials setting page, which you can find these three parameters.

 

Here is an example, if it is the first time to set the parameters, we need to enter a six-digit password, the default password is 000000. Then enter the setting page, to set the minimum feed weight as 300g, and the minimum discharge weight is also set to 300g. Then we can set IN/OUT delay time to 1s, back to the home page. 

 

To verify if the setting parameter works, we put a 200g weight here, you can find there is no changes on GMT-H1, Likewise, we remove the weight, there is also no changes on display, as well as no signal for incoming and outgoing materials. That is because 200g is less than the minimum in/out weight we set. However when the 500g weight is placed on, we find that there is an in-feed symbol and the value is displayed after one second, and when the weight is removed,  the out-feed symbol is also displayed and the value is updated to the current WT after one second.

 

So the minimum IN/OUT weight means that when the material weight changes positively or negatively more than the set value, the weighing transmitter will consider that as a valid feeding or discharging action. The IN/OUT delay time provides that if the weight no longer changes within the set time, then the feeding or discharging is considered complete and the weight data is displayed.

 

GMT-H1 also offers a data recording function, which allows you to view one entry of data and daily weight data as well as the total accumulated data by entering the historical data page, which can also be accessed through the various communication protocols, like RS485,  Modbus-RTU, Modbus-TCP/IP, GPRS.
