3. Press SHIFT + REL to negate the resistance of the test
lead cables.
Note
(Do not set the calibrator output to standby after REL is
pressed else the test lead resistance will not be
compensated.)
4. Apply a resistance of 1Ω (standard resistor reference) to
the GDM-8245. 1Ω±4 digits.
5. Repeat steps 1 and 2 for the remaining ranges and
resistances.
Resistance verification is complete.

Verification
procedure
1. Set the multimeter to diode mode.
2. Connect the fixture as shown. A voltage
between .5V~.7V should be shown.
3. Reverse the polarity of the connection. OL (overload)
should be displayed on the DMM.
