3.3.3 Null(Relative)
Definition
When the null function is enabled, the displayed measurement reading will show
something difference between the measured input signal reading and the stored null
(also called relative) value. The null (relative) value is stored in a volatile memory and
the value will be cleared when the multimeter is power-off. Moreover, you can specify
or alter a null value. The null function is available for all types of measurement except
continuity and diode. When you select the null function for a measurement, it is visible
only for this measurement.
How to operate null (relative) measurement
You can operate the null function from either the front panel operation or the remote
interface operation.
The Front Panel Operation
Way One:
Store the null test lead resistance: First of all, short the two test leads together and
then press NULL button. The new reading taken will replace the old value, if any, in
the null register. Then, connect the two test leads to the input source. The value with
null offset will show on the display.
Way Two:
Pressing NULL to actuate it. Or you want to define the value by doing the procedure
SHIFT + NULL > NULL > ENTER > RUN VALUE as shown in
Figure 3-24
. And use
◁
and
▷
to move through the digits and
△
and
▽
to increase or decrease the numbers
to a desired value. Then press ENTER to actuat it.
※
Note: Press NULL again to disable this feature. The “MATH” anunnciator on the
display indicates the state of a mathematical feature.
