Calibrate the transmitter. • If the fail condition continues, replace the CO sensor. • If the fail condition continues, contact RKI for further instruction. Slow or No Response/Difficult or Unable to Calibrate 8 • 65-2434RK CO Transmitter 1.800.561.8187 information@itm.com www. .com... -
Page 13: Replacing Components Of The Co Transmitter
Verify that the calibration cylinder contains an adequate supply of a fresh test sample. If the calibration/response difficulties continue, replace the CO sensor as described later in this section. If the calibration/response difficulties continue, contact RKI Instruments, Inc. for further instruction. Replacing Components of the CO Transmitter This section includes procedures to replace the CO sensor, amplifier PCB, and charcoal filter. - Page 14 Remove the enclosure’s cover by unscrewing the four cover screws, one at each corner. Unplug the CO sensor from the amplifier PCB. Remove the rubber boot that secures the charcoal filter to the CO sensor. 10 • 65-2434RK CO Transmitter 1.800.561.8187 information@itm.com www.
