Checking the Relative Value/Performing Zero Adjustment
4.7 Checking the Relative Value/
Performing Zero Adjustment
The relative value comparing to the standard value can be checked
(relative function).
It can also be used as the zero adjustment function.
Zero adjustment eliminates the inuences of the wiring resistance
(resistance measurement) and the wiring capacity (capacitor
measurement).
When the following measurement function is selected, this function
is disabled.
Peak measurement, Continuity, Diode, dBm/dBV, 4-20 mA
The measurement range cannot be changed when [REL] is lit. To
change the range, press REL for at least 1 second to reset the
REL function.
