Gear selection

 When DIP switch 1 is turned OFF, VO output is 0-5V.When DIP switch 1 is turned ON, VO output is 0-10V. When DIP switches 1 and 2are both turned OFF, VO output is 0-5V. Output 4-20mA. The other terminal ofthe current output and voltage output is GND, which is the same negativepolarity as the power supply.

Zero adjustment 

1: Voltage Adjustment Firstly, make the system inno-load condition and adjust the zero voltage adjustment potentiometer (Vzero)to adjust the zero point. Use a multimeter to measure the output VO voltage sothat the indication is as close as possible to the zero point indication.

2: current adjustment First, the system is in no-loadstate, adjust the current zero point potentiometer (Izero), measure the outputcurrent IO with the multimeter current block, try to make it close to 4mA. 

Gain adjustment 

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

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