6. Diode Test Check
a. Set the DM 5010 controls to the preliminary settings.
b. Connect a 604 Ω resistor between the DM 5010 HIGH
and LOW input connectors.
c. Press the DIODE TEST button (on).
d. CHECK— that the display reads between 0.5484 V
and 0.6054 V.
NOTE
The rear interface ohms offset and accuracy checks
need not be made unless the instrument is used for
measurements via the rear-interface connections.
7. Rear Interface Ohms Offset Check
For this check, short the power module connections to
the DM 5010 rear-interface pins 28B (Hi) and 28A (Lo) on
the ADC board (A17). Access to these pins is most easily
made using a TM 5000-Series, Option 02 power module.
a. Set the DM 5010 controls to the preliminary control
settings with the following exceptions:
e. Remove the resistor.
