Step 12: Press the calibrator CHK MOM switch. All the indicators on
the discrete output card should remain unlit. If any of the
indicators on the discrete output card are lit, the discrete
output card requires repair.
Note
For cards with momentary output, hold down the
CHK MOM switch long enough to ensure card has
time to respond. If the card has switches S1
through S8, closure times are user-adjustable. For
these cards the indicators on the card and the
MUX DO/DI indicators on the calibrator stay on for
0.1 to 25.5 seconds, as determined by the
individual channel switch settings. The closure
time is equal to the sum of the activated switch
times. Individual switch times are silkscreened on
the card next to the switch positions.
Step 13: Set the calibrator ON/OFF switch to OFF.
Step 14: Disconnect the umbilical cable and remove the discrete
output card.
