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.
