Model 6517B Electrometer Reference Manual
Section 16: Verification procedure
6517B-901-01 Rev. C / August 2015
16-3
Considerations
Always used fixed ranges for verifying voltage, current, and charge, because autoranging hysteresis
may cause the instrument to be on the incorrect range.
To restore the instrument to factory defaults:
1. Press
the
MENU
key; the following menu is displayed:
MAIN MENU
SAVESETUP COMMUNICATION CAL
2. Select
SAVESETUP
using the left or right arrow keys, and then press
ENTER
. The following
menu is displayed:

3.
Select
RESET

Verification procedures
All test configurations must be properly grounded. If the triaxial to BNC adapter ties the BNC ground
to the triaxial inner shield, the
DC Volts Guard
must be off for the operation to be correct. If the
triaxial to BNC adapter ties the BNC ground to the outer shield of the triaxial connector, a separate
path to ground must be supplied to obtain the correct measurement. This can be accomplished two
different ways:
Take the ground lead (located on the back of the Model 6517B, connected to the ground screw
next to the Keithley logo) and plug it into the common terminal of the Model 6517B (located
between
Preamp Out
and
2V Out
). This is preferred as it minimizes the loop area for noise
pickup.
OR
Connect a separate wire from the Model 6517B electrometer common to the low terminal of the
DC voltage calibrator.
