Model 200E Instruction Manual
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.

The analyzer is placed in Zero Calibration mode. The mode field
of the display will read ZERO CAL R .
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 .
The analyzer is placed in Span Calibration mode. The mode field
of the display will read SPAN CAL R .
The ground level from the analyzer's internal DC power supplies
(same as chassis ground).
Input pin for +5 VDC required to activate pins A - F.
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).
