Quality evaluation of domestic weighing transmitter

1. Main features of domestic weighing transmitter Can drive 6 analog sensors of 350w Maximum a\/d pulse number: 1,000,000 Update rate: 100 times\/second Analog output type can be selected: 4-20ma, 0-20ma, 0- 24ma, 0-5v (0-10v) high precision, high resolution δ-σ type a\/d conversion kh01-a1 type weight transmitter built-in 4-way load cell wiring terminals, using a sealed shell, the protection level is ip67 , The working temperature range is -30 degrees Celsius -60 degrees Celsius, which can be used in various industrial environments.

2. Adjust the lt; zero gt; knob on the panel of the amplification module to make the output voltage of the amplification module -4.5V (the detection voltage on the software is -4.5v or the detection zero point is 0.5V), and then click on the software lt;Zero and tare gt; button to make the weight display window display about zero, and then put on the weight to calibrate. After the calibration is completed, check that the conversion factor is a little higher than the actual maximum weight of the scale.

3. If the range is too small (the conversion factor is too small), you can adjust the lt; zoom gt; knob on the module again to make the detection voltage or detection zero point rise (counterclockwise rotation means the voltage rises about 2V each time). Then adjust the lt; ;Zero gt;The knob reduces the voltage to (counterclockwise rotation is to reduce, the detection voltage is -4.5V or the detection zero point is 0.5V. Click the software's lt again; zero and tare gt; then put the weight to calibrate say.

4. During the debugging and use process, it is not allowed to plug and unplug the weighing transmitter, which is easy to burn out the internal precision components. When you need to plug and unplug the weighing transmitter, turn off the power switch before operation. Debug or use During the process, it is found that the temperature of the module shell is too high, please cut off the power to check whether the power cord of the sensor connected to the module is short-circuited or misconnected.
