7866 Remote Indicator Input Calibration

Disconnect the PV Input terminals from the Analyzer output and connect them to a voltage milliampere source. For
zero and span enter values which are consistent with the PV Input selection (1-5 volts or 0-5 volts).
NOTE: Input 2 is not used during Calibration of Input 1.

If, after the Zero or Span "live" value has stabilized, no change is made, you should still perform the same key-press
sequences. For example, if in Step 5 you make no change to the displayed value, continue to Step 7 by pressing the
FUNCTION key twice.

Table 5-4 PV Input Calibration

Connect the input source to the PV Input terminals. Set the source value to the
zero value.
until you see:
Upper Display: CALIBR
Lower Display: PVINPUT
You will see:
Upper Display: DISABL (default selection)
Lower Display: PVINPUT
Select CALIB to begin manual calibration procedure for Range 1.
You will see INP ZERO in the Lower Display.
The value shown in the Upper Display is a "live" reading. Wait until the value
becomes stable for the zero reading.
Captures the displayed value. The display will blink once indicating that you can
use the or keys to change to the desired zero value. (This ties the internal
counts processed for the input conversion to the desired value for Zero.)
Saves Input ZERO data.
You will see INP SPAN in the Lower Display.
Set the source to the span value. The value shown in the Upper Display is a "live"
reading. Wait until the value becomes stable for the span value.
Captures the displayed value. The display will blink once indicating that you can
use the or keys to change to the desired span value. (This ties the internal
counts processed for the input conversion to the desired value for Span.)
Saves Input SPAN data and processes the Range 1 calibration calculation.
