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.
Use

◁

and

▷

buttons to move through the digits and use

△

and

▽

buttons to increase or

decrease the numbers to a desired value. Press ENTER to set the value. The locations of the
buttons are shown with red rectangle frames in

Figure 4-17

.

※

Note: Press NULL again to disable this feature. The “MATH” anunnciator on the display

indicates the state of a mathematical feature.
