Additional Functions
Several functions can be controlled via the Key Pad that will produce different actions depending
on the instrument operating mode:
TARE and Reset TARE functions
To configure the meter for Tare mode, press the
UP
key while in
RUN
mode and the meter will
store the currently displayed value as the tare value (unless it is over scaled) and the
TARE
Led
will light. From this point the value displayed on the meter is the net value, i.e., the measured
value minus the stored tare value. If a tare value has been stored, pressing the
UP
key again will
add the currently displayed value to the previously stored tare value resulting in a new stored
tare value. To reset the tare value to zero, press the
UP
key for 3 seconds while in
RUN
mode.
The
TARE
Led will turn off and the displayed value will be the gross value (without the tare).
MAX/MIN function
With the meter in
RUN
mode: Activated after pressing the
SHIFT
key for less than 3 seconds.
From
RUN
mode, a press shows the maximum value read by the instrument since the last time
it has been switched on, unless a
RESET MAX/MIN
is done, the display will alternate between
“Hi”
and the maximum stored value. With a second press the display will alternate between
“Lo”
and the minimum stored value. A third press brings the instrument back to
RUN
mode.
Reset MAX/MIN
While the meter shows the peak value
(MAX)
, pressing the
SHIFT
key for 3 seconds will
produce a reset of the value. Pressing
SHIFT
key for 3 seconds while the meter shows the valley
value
(MIN)
will produce a reset of the value.
