HOLD Button
The hold button allows the user to freeze the display when it is pressed. When pressed again the display returns to
it’s normal operating mode. When in hold mode the display will flash and the hold annunciator will be lit, to ensure
that this feature is not accidentally turned on without the user noticing.
The hold feature cannot be used when the 9320 is in either peak or valley hold mode.
GROSS/NET Button
The gross/net button, when pressed, toggles between the gross and net display values. This enables the user to
zero the display (by putting the 9320 into net mode) and displaying the change in display value from that point.
This is useful for certain weighing applications where a tare weight exists, which can be removed by putting the
9320 into net mode.
SHUNT CAL Button
The shunt calibration button, when pressed, puts an internal 100kΩ resistor across the –ve excitation and –ve signal
of the sensor, generating a simulated output from the sensor, therefore giving a simulated display value. This can
be pressed immediately after the sensor has been calibrated with the 9320 and noted down for later reference. The
value noted can be used to get an idea of the calibration accuracy at a later date, or for checking the integrity of
the sensor and sensor cabling.
The shunt calibration resistor can be changed to suit specific requirements. It is suggested that a 15ppm ±0.1%
tolerance resistor is used.
PEAK Button
When pressed this button puts the 9320 into peak mode. This will display the highest display reading and hold it on
the display until it is reset or a higher value is reached. To reset the peak display, press the peak and valley buttons
simultaneously. In peak mode it is possible to capture peaks at a rate of up to 25Hz. To turn off the peak mode,
press the peak button.
VALLEY Button
When pressed this button puts the 9320 into valley mode. This will display the lowest display reading and hold it on
the display until it is reset or a lower value is reached. To reset the valley display, press the peak and valley
buttons simultaneously. In valley mode it is possible to capture valleys at a rate of up to 25Hz. To turn off the
valley mode, press the valley button.
