The RANGE button allows the user to toggle between two independent scales. An
annunciator highlights the range that has been selected.
The HOLD button allows you to hold/freeze the current display value when the button is
pressed. Pressing the HOLD button again releases the display. The HOLD annunciator is
illuminated when in the HOLD mode, and the display will flash to alarm further that the
user is not viewing instantaneous display values
The GROSS/TARED button, when pressed, allows the user to toggle between displaying
the Gross or Tared display values. This can be useful in many applications where it is
necessary to display the change in display value from a certain part of the measurement
range. When in TARED mode the TARED annunciator is lit. When in GROSS mode, the
TARED annunciator is not lit.
The SHUNT CAL button allows the user to press this at any point in time. The standard
unit shunts a 100kΩ resistor across the negative excitation and negative signal
connections. If this is performed at the end of the calibration procedure, then a figure can
be noted, so the user can check calibration accuracy or connection integrity. The button
has to be held down to operate. When held down the SHUNT CAL annunciator is lit and
the display will flash, to alarm further that the user is not viewing instantaneous display
values.
When the PEAK button is pressed the display will show the last Peak reading. To reset the
Peak readings press the PEAK and VALLEY buttons simultaneously. When in PEAK mode
the PEAK annunciator will be lit and the display will flash, to alarm further that the user is
not viewing instantaneous display values. To turn off Peak mode press the PEAK button.
When the VALLEY button is pressed the display will show the last Valley reading. To reset
the Valley readings press the VALLEY and PEAK buttons simultaneously. When in VALLEY
mode the VALLEY annunciator will be lit and the display will flash, to alarm further that the
user is not viewing instantaneous display values. To turn off the Valley mode press the
VALLEY button.
