4. Select a manual measurement range that is consistent
with the expected reading, or enable auto range (see
paragraph 2.12 for detailed range information).
5. Connect the Model 6517A to the voltage to be mea-
sured. Figure 2-20 shows typical connections for un-
guarded measurements, and Figure 2-21 shows typical
connections for guarded measurements.
WARNING
Hazardous voltage may be present on
the inner shield of the triax cable when
GUARD is on. A safety shield connect-
ed to safety earth ground (as shown in
Figure 2-21) should be used for voltage
measurements at or above 30V.
6. Press Z-CHK to disable zero check and take a reading
from the display.
NOTE
To disable zero correct, enable zero check
and press REL.
