4-3Input and Output Card
Original — December 1991 UM4.6:CS6003
Step 3: Connect the umbilical cable labeled MUX DI/BREAKOUT
between the connector on the front of the single-ended
analog input card and the calibrator receptacle labeled
BREAK-OUT CONNECTOR.
Step 4: Turn the calibrator ON.
Step 5: Press the calibrator MUX switch to test the card. The
calibrator numerical display shows one of the following:
No Code — The card requires repair; terminate procedure
and obtain a replacement card
0001 — The card is a 1 to 5 volt input type; continue
procedure
0033 — The card is a 0 to 10 volt input type; continue
procedure
Any Other Code —The card is not a single-ended analog
input card or requires repair; terminate procedure and
obtain a replacement card
Step 6: Set the calibrator CHANNEL SELECT switch to channel 1.
Step 7: Connect the voltage source between calibrator breakout
terminals 1 (Channel 1 Input) and 2 (Input Common).
Step 8: Press the calibrator AI1 group mode switch.
Step 9: If the single-ended analog input card is a 1 to 5 volt input
type, set the voltage source to 0.020 volts. If the single-ended
analog input card is a 0 to 10 volt type, set the voltage source
to 0.050 volts. Adjust the ZERO potentiometer until the
calibrator numerical display reads 0016.
Step 10: If the single-ended analog input card is a 1 to 5 volt input
type, set the voltage source to 5.000 volts. If the single-ended
analog input card is a 0 to 10 volt input type, set the voltage
source to 10.000 volts. For a 1 to 5 volt card, adjust the SPAN
until the calibrator numerical display reads 4000. For a 0 to 10
volt card, adjust the SPAN potentiometer until the calibrator
numerical display reads 3200.
Step 11: Repeat steps 9 and 10 until no adjustment is required for
either step.
Step 12: To verify the settings, repeat steps 6 through 11 for other
channels. Table 4-1 lists the correct breakout terminals for the
other channels for step 7. If any tested channel does not
produce a correct value and cannot be calibrated, the
single-ended analog input card requires repair.
