10 • 65-2336RKSS CO Transmitter
For example, with a test sample of 50 ppm CO and a fullscale setting of
300 ppm, the correct output is 167 mV.
167 (mV) = (50/300) X 400 +100
7. Screw the regulator into the calibration cylinder.
8. Use the sample tubing to connect the regulator to the calibration cup.
Performing the response test
1. Turn the regulator’s on/off knob counterclockwise to open the regulator. Gas will
begin to flow.
2. Allow the gas to flow for two minutes, then verify that the reading is within ± 20% of
the response reading you determined earlier.
NOTE: If the readings are not within ± 20% of the correct response reading, calibrate the
affected transmitter(s) as described in “Calibration” on page 14.
3. Turn the regulator’s on/off knob clockwise to close the regulator.
4. Unscrew the regulator from the calibration cylinder.
5. Unscrew the calibration cup from the CO detector.
6. Remove the voltmeter leads from the amplifier test points.
7. Reinstall the junction box cover.
8. When the controller display reading falls below the alarm setpoints, return the
controller to normal operation.
9. Store the components of the calibration kit in a safe place.
Quarterly
Calibrate the CO transmitter as described in “Calibration” on page 14 of this manual. See
the calibration frequency discussion in “Calibration Frequency” on page 14 to determine
if a quarterly calibration schedule fits your needs.
Troubleshooting
The troubleshooting guide describes symptoms, probable causes, and recommended
action for problems you may encounter with the CO transmitter.
NOTE: This troubleshooting guide describes transmitter problems only. See the
controller instruction manual for problems you may encounter with the
controller.
