Step 13: Disconnect the jumpers from +CO2 and –CO2 breakout
terminals and connect the jumpers to the +CO1 and –CO1
breakout terminals. The voltmeter should read 5.00
± 0.01
volts dc. If not, adjust the process I/O card Current Output 1
SPAN (R17) potentiometer for the proper reading.
Step 14: Press the CAL LOW mode switch and observe the voltmeter.
The voltmeter should read 1.00
± 0.02 volts dc. If not, the
process I/O card requires repair.
Step 15: Disconnect the jumpers from the +CO1 and –CO1 breakout
terminals and connect the jumpers to the +CO2 and –CO2
breakout terminals. The voltmeter should read 1.00
± 0.02
volts dc. If not, process I/O card requires repair.
Step 16: Press the SCAN switch and observe the CAL STATUS
indicators. The OK indicator should light. If the SCAN ERROR
indicator lights repeat Steps 8 thru 16 to produce the proper
indication.
Step 17: Disconnect the voltmeter and jumpers.
Step 18: Set the calibrator ON/OFF switch to OFF.
Step 19: Remove the process I/O card.
5.2 Type CL6011 Interactive Controller Card
The calibration procedure for the interactive controller consists of two
separate procedures. The interactive controller is not calibrated as a
single unit. The MPU card and discrete I/O card (if present) are tested
together. This is a functional test, there are no user adjustments on
these cards. Only one process I/O card may be calibrated at a time. The
calibration procedure for the process I/O card allows the user to adjust
the 0 percent (ZERO) and 100 percent (SPAN) voltage levels of the
analog-to-digital conversion circuit. It also allows the measurement of the
0 percent and 100 percent values of the analog current outputs and the
adjustment of the 100 percent values of the analog current outputs.
5.2.1 MPU Card
Use the following procedure to calibrate the MPU card.
