REL

The reading displayed on the screen in REL operation is the difference between

measured and preset values.

Reading = measured value – preset value

Users can pre-specify a REL value by any of the following way:

1) In basic measurement interface, press REL and the multimeter automatically

uses the current measurement result as the preset value.

2) In basic measurement interface, press  Math  REL to enter the preset

value setting interface.

3) In basic measurement interface, press  REL to enter the preset value

setting interface.

In the preset value setting interface, you can directly use the direction keys to

specify a preset value. The unit is decided by the current measurement function.

Current: set the preset value to the current reading.

Clear: restore the preset value to 0.

On/Off: enable or disable REL operation. When it is on, pressing

will go to the

measurement main interface, as shown in the figure below.

 The status bar displays “REL”.

 The REL operation result is displayed at the center of the screen.

 Repressing REL under the main interface will close the REL operation. The

identifier “REL” disappears.
