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 internal +5V 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.

REMOTE ZERO CAL
The analyzer is placed in Zero Calibration mode. The mode
field of the display will read ZERO CAL R.

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.

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).
