The second step: Read the weight. One is average weight and the other is real-time weight. We usually read average weight.
The third step: Adjust the stability and responsiveness of weighing. The above two factors affect the sampling frequency, average
number and filtering rate. Therefore, we can adjust the above three parameters get proper stability and responsiveness .
The fourth step: In order to make the usage more convenient, we also provide the status-value for the load Cell Module,if the
current status is like no-load, exceeding the upper limit, or value measurement with stability. We can achieve the automatic
judgment control of weighing. At the same time, it also has the functions of gross weight setting, zero-point tracking, automatic
tare-removing, and so on.
To introduce the weighing Module programming and practical use.
3. Hardware Configuration
In this case, the host is N40S2T, with a load Cell Module, so the hardware configuration is as follows:
4.Weight 16-bit/32-bit display switching
Module weight 16-bit display and 32-bit weight display are two modes. Take Channel One as an example, 16-bit/32-bit weight
switching can be realized by CR13H, 16-bit display for 13H writing 0 and 32-bit display for writing 1. The program example is as
follows.
5.Calibration methods and program examples
The weighing module supports three-stage calibration and can realize multi-range and one-time scale calibration. Taking Channel
1 as an example, the calibration steps are as follows:
User operation steps:
Step1: No weight is put on the weighing unit.
Step2: CR26H write value 1, enter the calibration mode;
Step3: In the first paragraph, a standard weight is added to the weighing unit, 16-bit scale writes the weight on the current chassis
into CR27H, 32-bit scale writes into CR27H and CR28H, if no multi-stage calibration criteria are needed to Step6;
Step4: If the second calibration is needed, add another standard weight to the weighing unit, 16-bit scales will write the weight on
the current chassis into CR29H, 32-bit scales will write into CR29H and CR2AH, if there is no need for multi-stage calibration
criteria to Step6;
Step5: If you need the calibration in paragraph 3, add another standard weight to the weighing unit, 6-bit scales will write the
weight on the current chassis into CR2BH, 32-bit scales will write into CR2BH and CR2CH, if not to Step6;
Step6: CR26H writes value 2 to end the calibration process.
Examples of multi-section calibration procedures are as follows:
