4.3.4 Null
Definition
When null function is enabled, the displayed measurement reading is
the 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 feature is available for all functions, except continuity, diode.
When you select the null feature for a measurement, it is visible only
for this measurement.
How to use null (relative) measurement
You can activate null feature from either the front panel operation or
the remote interface operation.
The Front Panel Operation
The null measurements can be used with any function except
continuity and diode.
To store the null test lead resistance, 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. In addition, the null offset value can be
adjusted manually by pressing CONFIG then NULL. Use
