name or index number of desired channels is not known, enter ? to display a window containing
channel type channels. Use arrow keys to scan through the list. Press Return to select highlighted
channel.
(a) Channel Name Channel Reading
(b) Enter the first calibration point: ____________
(9) Connect signal source (see setup figure of Table 3-3 through Table 3-6) as close to user signal
source as practical. Table 3-3 through Table 3-6 list signal and conditioning control unit (SCCU)
connector pins to which channel is connected.
(10)Set signal source to low cal point (see Table 3-3 through Table 3-6).

NOTE
If a single point (offset) calibration is desired, press Return without entering second
calibration point.
(13)Set signal source to high cal point (see Table 3-3 through Table 3-6).
(15)Press Retrn to save the calibration. Display will read as follows:
(a) Satisfactory? (Y/N):____
(16)Make the appropriate response to return to step 9. Repeat steps 9-17 for similar channel types or
press Retrn to return to calibrate a Channel menu or step 8 to select a different channel type.
(17)Repeat steps 8-17 until all channels are calibrated.
(18)When calibration is complete, place CAL-RUN switch in RUN position.
(19)Reinstall CIRCUIT BOARD ACCESS cover.
