Depending on the function
selected, make

APPLICATIONS
2-134.
Specific applications using the
multimeter
are
presented in
Table
2-6.
The
applications may
be used as
examples to aid in familiarization with the
multimeter. If
the applications are duplicated,
modes or values already
programmed could interfere with the
expected
instrument response.
Therefore,
a power-up
or reset
instrument configuration is a precondition.

REQUIREMENT
:
Monitor
the
stability
of a power supply in terms
of its deviation in
volts
from a present
output of +5. 03V.
METHOD:
Store
the present output as an offset.
Press:
STORE -OFFSET
Offset is now enabled. The
multimeter will read only the deviation from +5.03V.
REQUIREMENT:
Monitor the stability
of a power supply as a
decimal ratio
to its
present reading of
-20.08V. DC zeroing
appears to be necessary.
METHOD:
Perform
V DC Zeroing for interna! drift. Apply low thermal short between INPUT HI
and LO (at the terminals). Press:
ZERO
VDC/Q
The value stored
will
be
displayed as long as
ZERO VDC/fi is held
depressed.
Release
of the switch will activate the
Zero mode. Revise terminal interconnections
for dc
volts measurements.
Connect the dc voltage.
Apply
power supply reading of -20.08V as a
scaling factor. Press:
STORE
SCALING
Display will now yield the ratio of
subsequent
readings to the
scaling factor,
e.g.,
an
input of 22.08V yields a ratio of:
22.088
