w The tested power value Apparent power value Power factor value
STO
The current measurement reading The value of the corresponding index number Index number increase one.
Index number: no.01~no.10
RCL The recalled value The total number of stored value. Index number: no.01~no.10
MAX MIN Chapter 2 Getting Acquainted – Using MAX MIN
REL
The present measurement value minus the
stored value The stored value The present measurement value.
Selecting the Range
Press RANGE to select either a fixed range or the autorange feature.
Autoranging (AUTO lighted in the display) always comes on initially when you select a new function. In autorange, the Meter selects the lowest input range possible, ensuring
that the reading appears with the highest available resolution.
If AUTO is already on, press RANGE to enter MANUAL ranging in the present range. You can then select the next manual range each time you press RANGE . Return to
autoranging by press EXIT .
Note that there is no MANUAL ranging on REL feature.
