SWITCH DEFINITIONS
Mode Selection Switch (S1)
S1 is used to cycle through the various set points, Hysteresis, and calibration values and decimal
point locations. The sequence is as follows. The designators, in parenthesis, identify text that
will be displayed, momentarily, followed by the value.
Set Point High 1 (SPH1)
Set Point Low 1 (SPL1)
Set Point High 2 (SPH2)
Set Point Low 2 (SPL2)
Hysteresis High (HH)
Hysteresis Low (HL)
Auto Cal (CAL)
Decimal Point (dP)
Exit
While in the Mode Selection sequence, the indicator is no longer monitoring the input signal. To
exit, depress S1, once, after the Decimal Point selection is completed.
Increment Switch (S2)
This switch serves two functions, depending on the present status of S1. If the instrument is in
the Mode Selection sequence, this switch increments the flashing digit.
If the instrument is in its normal operating mode, S2 becomes the TARE switch. If the TARE
LED, located on the front panel, is not illuminated, depressing S2 once will automatically zero
the readout and illuminate the TARE LED. Depressing S2 again will UNTARE the readout and
extinguish the TARE LED. TARING is accomplished by storing the reading prior to TARING
and subtracting this value from all subsequent readings. It does not alter the calibration of the
instrument. A remote tare function is available. See Section 6.0.
