Operation of Hold Mode
Warning
To avoid possibility of electric shock, do not use Hold mode to determine if circuits are without power. The Hold mode will not capture
unstable or noisy readings.
The Hold mode is applicable to all measurement functions.
••
Press
HOLD
to enter Hold mode; the Meter beeps.
••
Press
HOLD
again or
RANGE
or Hz % or turn the rotary switch to exit Hold mode; the Meter beeps.
••
In Hold mode, isdisplayed.
The Use of Relative Value Mode
The REL mode applies to all measurement functions except frequency/duty cycle measurement. It subtracts a stored value from the
present measurement value and displays the result.
For instance, if the stored value is 20.0V and the present measurement value is 22.0V, the reading would be 2.0V. If a new
measurement value is equal to the stored value then display 0.0V.
To enter or exit REL mode:
••
Use rotary switch to select the measurement function before selecting
REL
∆∆
. If measurement function changes manually
after
REL
∆∆
is selected, the Meter exits the REL mode.
••
Press
REL
∆∆
to enter REL mode, auto ranging turns off except under capacitance testing mode, and the present measurement
range is locked and display “0” as the stored value.
••
Press
REL
∆∆
again or turn the rotary switch to reset the stored value and exit REL mode.
Pressing
HOLD
in REL mode makes the Meter stop updating. Pressing
HOLD
again to resume updating.
