6. Apply 10.000V (±500 μV) and allow to settle for a minimum of 200 ms.
7. Send the Accept High Calibration command.
8. If both samples were successful the module saves data to Dataflash, recalculates
module parameters and exits calibration automatically.
Calibration can be aborted or restarted at any time. Data is not saved until the end of step 7.
Output Calibration
The wiring method decides the operating mode of current or voltage output. Calibration data
of both voltage and current are stored in nonvolatile memory and selected according to
parameter value of AO OUTPUT RANGE.
So select output range of either current or voltage prior to calibration.
Example current calibration of channel 0.
1. Set output channel range to 0…20 mA.
2. Select output channel 0.
