3.3.4 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, user can specify or alter a null value. The null
feature is available for all functions, except continuity, diode. When user selects 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.
