Set the calibration value, and tap OK.
The speciîš¿ed calibration value is written, and the corresponding value is output.
Repeat the procedure until the multimeter reading falls within the values correspond-
ing to the output accuracy.
Example of the accuracy range for voltage measurement (voltage drop method, resis-
tance: 250 Ω)
Range Output Accuracy Range Digital Multimeter Indication Range
(Resistance:250Ω)
4 mA 3.98 to 4.02 mA 995 to 1005 mV
20 mA 19.98 to 20.02 mA 4995 to 5005 mV

Perform a procedure similar to steps 6 to 8 to calibrate the 20 mA range.
10
To calibrate another channel, wire the channel you want to calibrate, and perform
steps 6 to 9.
11
When all the channels have been calibrated, tap Save.
The calibration values are saved.
To reset the calibration values to their factory defaults, tap Reset.
You do not have to tap Save.
12
To calibrate a different module, tap Back, and carry out the steps from unit selection
(step 4) or module selection (step 5).
