• SWITCH DEFINITIONS •
Prog/Oper Switch (S1)
– S1 places the indicator in PROGRAM or OPERATE mode. When in
PROGRAM mode, pressing S1 advances the readout to the next program step. While at each step, a
display prompt (identifying the parameter) is shown in parentheses for approximately one second. This
prompt is then immediately followed by the actual value for that parameter. Starting from OPERATE,
the sequence of steps is as follows:
PROGRAM STEP
DISPLAY PROMPT
Set Point 1 High
(SPH1)
Set Point 1 Low
(SPL1)
Set Point 2 High
(SPH2)
Set Point 2 Low
(SPL2)
Hysteresis High
(HH)
Hysteresis Low
(HL)
Calibration Value
(CAL)
Decimal Point
(dP)
Exit to OPERATE Mode
Pressing S1 once more after DECIMAL POINT step returns the instrument to OPERATE mode,
displaying the current value of the input.
Up/Zero Switch (S2)
– S2 serves two functions, depending on the status of S1 (PROGRAM or
OPERATE). While in PROGRAM mode, S2 increments the flashing digit or shifts the DECIMAL
POINT left. While in OPERATE mode, S2 becomes the ZERO SWITCH: pressing S2 when the ZERO
LAMP is
not
lit will light the lamp and subtract that display value from all subsequent readings. Pressing
S2 when the ZERO LAMP is lit will extinguish the lamp and cancel the subtraction.
Down/Cal Switch (S3)
– S3 serves two functions, depending on the status of S1 (PROGRAM or
OPERATE). While in PROGRAM mode, S3 decrements the flashing digit or shifts the DECIMAL
POINT right. While in OPERATE mode, S3 becomes the CAL SWITCH: pressing S3 when the CAL
LAMP is
unlit
will light the CAL LAMP and scale the display to read the CALIBRATION VALUE.
Pressing S3 when the CAL LAMP is lit will extinguish the CAL LAMP and return the indicator to
displaying the base unit input voltage directly in volts. (NOTE: disregarding display decimal point
position, the base unit nominally displays 10000 when its input is 1 VDC.)
Step/Hi/Low Switch (S4)
– S4 serves two functions, depending on the status of S1 (PROGRAM or
OPERATE). While in PROGRAM Mode, S4 selects the display digit. The selected digit will flash and
will respond to increasing by S2 or decreasing by S3. While in OPERATE mode, pressing S4 displays
the prompt “HI” for one second followed by the High reading for one second. It will automatically
continue with the prompt “LO” for one second and the Low reading for one second, before finally
returning to the standard display.
Lockout Switch (S5)
– Placing the rear panel toggle switch S5 in the up position
disables
switches S1
through S4.
