e)
20 mV voltage range calibration
•
Connect cable adapter Option 80 to the AUXILIARY connector.
•
Make short of test wires of Option 80 adapter.
•
Press SELECT display button to select the first calibration point of 20 mV range, 0 mV.
•
After the value stabilizes, press WRITE display button to write new calibration value.
•
Connect external standard multimeter set to the mVDC function to the Hi – Lo output
terminals. Use test wires from basic delivery. Connect HU test wire of cable adapter to the Hi
terminal on the calibrator and LU test wire of cable adapter to the Lo terminal on the
calibrator. Both build-in meter and external multimeter are in parallel. If necessary, adjust zero
of standard multimeter before calibration.
•
Press SELECT display button to select 19 mV calibration point. Red LED is lit above
OUTPUT button.
•
Set such output voltage on the calibrator, that standard multimeter indicates 19.000 mV
•
After the value stabilizes, press WRITE display button to write new calibration value.
Terminals of the calibrator will switch OFF automatically.
•
Disconnect input wires of Option 80.
f)
200 mV voltage range calibration
•
Make short of test wires of Option 80 adapter.
•
Press SELECT display button to select the first calibration point of 200 mV range, 0 mV.
•
After the value stabilizes, press WRITE display button to write new calibration value.
•
Connect external standard multimeter set to the mVDC function to the Hi – Lo output
terminals. Use test wires from basic delivery. Connect HU test wire of cable adapter to the Hi
terminal on the calibrator and LU test wire of cable adapter to the Lo terminal on the
calibrator. Both build-in meter and external multimeter are in parallel. If necessary, adjust zero
of standard multimeter before calibration.
•
Press SELECT display button to select 190 mV calibration point. Red LED is lit above
OUTPUT button.
•
Set such output voltage on the calibrator, that standard multimeter indicates 190.00 mV
•
After the value stabilizes, press WRITE display button to write new calibration value.
Terminals of the calibrator will switch OFF automatically.
•
Disconnect input wires of Option 80.
g)
2000 mV voltage range calibration
•
Make short of test wires of Option 80 adapter.
•
