Gain adjustment

1: voltage fullness adjustment will load the system with a certain weight value (recommended range: 80% ~ 100% FS), calculate the output voltage value according to the proportional relationship between the loaded weight and the maximum weight value, monitor output with a digital multimeter, rotating voltage full Potentiometer (Vspan) adjusts full output.

2: Current fullness adjustment Load the system with a certain weight value (recommended range: 80%~100%FS), calculate the output current value according to the proportional relationship between the loaded weight and the maximum weight value, monitor the output with a digital multimeter, and rotate the current full The Ispan adjusts the full-scale output as close as possible to 20mA.

Retest

Leave the system in no-load condition and measure zero output; load a certain weight value and measure whether the output voltage meets the expected amplification. If not, please adjust again.
