Application of Relative value measuring (REL)
1. Apply in Voltage measuring: If LCD has original data displayed, once you active the REL function, the LCD screens will
display symbol “
”, meanwhile, the original data will be counteract and showing as “000” (Resolution depends on your
measuring range), and then go on to voltage test as normal.
2. Apply in Resistance measuring: Switch the testing range to “Resistance measuring” and then insert the test pen with two
metal probe reliable connected (short-circuit), observe the reading, if initial reading existed, press the “REL” key and
then the LCD screen will display symbol “
”, meanwhile, the original data will be counteract and showing as “000”
(Resolution depends on your measuring range), and then go on to Resistance test as normal.
3. Apply in Capacitance measuring: Switch the testing range to “Capacitance measuring” and then insert the test pen with
two metal probe in open-circuit state, observe the reading, if initial reading existed, press the “REL” key and then the
LCD screen will display symbol “
”, meanwhile, the original data will be counteract and showing as “000” (Resolution
depends on your measuring range), and then go on to Capacitance test as normal.
