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, 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.
