Making Relative Measurements
When making relative measurements, reading is the
difference between a stored reference value and the input
signal.
Press
to enter the relative mode. The
measurement value when pressing
is stored
as the reference value. In this mode, REL
(current
reading) = input value - reference value.
Press it again to exit the mode. In relative
measurement, the manual range mode will be
activated automatically. (The relative measurement
should be carried out under a certain range, that is,
this function is only available under the manual range
mode.) Analog bar graph is not displayed.
Note
:
This function is not available when measuring diodes,
transistor, and frequency.

Buzzer Feature
Press the function key, the buzzer will sound “Be…” in
short.
One minute before Auto Power-off the buzzer will
sound “beep” five times to warn. Before it is shut off,
the buzzer will sound a long ” beep” then shut off.
The buzzer will sound “beep…” continuously to warn
when the measured DC voltage is higher than 1000 V,
AC voltage is higher than 750 V, or the measured
DC/AC mV mode is higher than 600.0 mV.
