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.
