The calibration adjustment will affect the instrumentation amplifier stage which follows the analog multiplexer. so the calibration affects all user input channels. Variations exist in the component parameters of each input circuit before the analog multiplexer will cause slight differences in the reading values between different channels connected to the same input signal even after calibration.If need to acquire the specifications contained in this data sheet, may be you need to enable analog input filters for all inputs of the module. Please select 64 or more samples to calculate the average value.To calibrate the input, please use the following steps.1. Turn off the power to the module, select the desired input range.2. Turn on the power to the CPU and module. Allow the module to stabilize for at least 15 minutes.3. Using a transmitter, a voltage source, or a current source, connect a zero value signal to one of the input channels.4. Read the value reported to the CPU from the input channel. Adjust the OFFSET potentiometer until the reading value is zero, or the desired digital data value.5. Connect a full-scale value signal to one of the input channels, read the value reported to the CPU. Adjust the GAIN potentiometer until the reading is 32000, or the desired digita data value.6. Repeat the OFFSET and GAIN calibration once more if requiredConfiguration

Repeat the OFFSET and GAIN calibration once more if requiredTable 1 shows how to configure the EM 135 module using the configuration DIP switches. Switches 1 through 6 select the analog input range and resolution. All inputs are set to the same analog input range and format. Table 2 shows how to select for unipolar/bipolar (switch 6), gain (switches 4 and 5), and attenuation (switches 1, 2, and 3). In these tables, ON is closed, and OFF is openTable 1 EM 135 Configuration Switch Table to select Analog Input Range and Resolution

Note
12 bits readings of the analog-to-digital converter (ADC) are left-justified in the input data word format. The MSB is the sign bit: zero indicates a positive data word value. In unipolar format, the three trailing zeros cause the data word to be changed by a count of eight for each one-count change in the ADC value. In bipolar format, the four trailing zeros cause the data word to be changed by a count of sixteen for each one count change in the ADC value.
Output Data Word Format
The 12 bits readings of the digital-to-analog converter (DAC) are left-justified in the output data word format. The MSB is the sign bit: zero indicates a positive data word value. The four trailing zeros are truncated before being loaded into the DAC registers. These bits have no effect on the output signal value.
