Calibration for input/output
1. Disconnect power and set the input range (SW2) and output range (SW1)
to the desired setting, then apply the power.
**Define the following variables for calibration use.
--Low_cali_input = Min_input + Full Scalar Input * 0.05;
--High_cali_input = Max_input - Full Scalar Input * 0.05;
--Low_cali_output = Min_output + Full Scalar Output * 0.05;
--High_cali_output = Max_output - Full Scalar Output * 0.05;
2. Input the Low_cali_input signal;read the Low_real_output signal;
3. Input the High_cali_input signal;read the High_real_output signal;
4. Adjust variable resistor of SPAN and repeat step 2 & 3 to meet the following
condition
(High_cali_output + Low_cali_output) = (Low_real_output + High_real_output)----eq1
