3.1.1.3. Connecting the Control Inputs
If you wish to use the analyzer to remotely activate the zero and span calibration modes,
several digital control inputs are provided through a 10-pin connector labeled CONTROL
IN on the analyzer’s rear panel.
There are two methods for energizing the control inputs. The in5V available from
the pin labeled “+” is the most convenient method. However, if full isolation is required,
an external 5 VDC power supply should be used.

INPUT # STATUS DEFINITION ON CONDITION
A
REMOTE ZERO CAL
The analyzer is placed in Zero Calibration mode. The mode
field of the display will read
ZERO CAL R.
B
REMOTE
LO SPAN CAL
The analyzer is placed in low span calibration mode as part
of performing a low span (midpoint) calibration. The mode
field of the display will read LO CAL R.
C REMOTE
SPAN CAL
The analyzer is placed in Span Calibration mode. The mode
field of the display will read
SPAN CAL R

Digital Ground
The ground level from the analyzer’s internal DC power
supplies (same as chassis ground)
U External Power input Input pin for +5 VDC required to activate pins A – F.
+
5 VDC output
Internally generated 5V DC power. To activate inputs A – F,
place a jumper between this pin and the “U” pin. The
maximum amperage through this port is 300 mA (combined
with the analog output supply, if used).
