Operation of Hold Mode
RANGE button
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.
In order to avoid the hazard arising from

button for around 15 minutes.
The meter can be activated by turning the rotary
switch or pressing any button.
To disable the sleep mode function, press BLUE
botton while turning on the meter.

WARNING
WARNING
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:
• Press
REL
to enter REL mode, and the present
measurement range is locked and display “0” as
the stored value.
• Press
REL
again to reset the stored value
and exit REL mode.
The BLUE botton
It uses for selecting the required measurement func-
tion when there is more than one function at one
position of the rotary switch.
