Repeat the procedure until the multimeter reading falls within the values correspond-
ing to the output accuracy.
Tapping STOP under Output to stops the output. The display changes to START.
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
11 Perform a procedure similar to steps 7 to 9 to calibrate the 20 mA range.
12 To calibrate another channel, wire the channel you want to calibrate, and perform
steps 7 to 11.
13 When all the channels have been calibrated, tap Save.
The calibration values are saved.
14 To calibrate a different module, tap Back, and carry out the steps from unit selection
