When the correct value is displayed, attach the regulator to the span gas cylinder and fl ow the
span gas over the sensor. Once gas is detected, display will show a countdown from 180 seconds (3
minutes).
NOTE : If an inappropriate concentration of span gas is applied during calibration, calibration may
succeed but it does not mean the equipment has been calibrated properly. CETCI is not responsible
for improperly calibrated transmitters. Follow manual instructions carefully.
When the process has fi nished and the Span calibration was accepted, remove the cylinder of span
gas. Refer to Section
7.3.4 Span - Requires Override
if the Span calibration was not successful.
Repeat the calibration steps above for each enabled gas channel.
NOTE: After 5 minutes of inactivity, the display will return to the normal operation.
NOTE: If required, the Zero Calibration and the Span Calibration procedures can be done
independently of each other. Refer to Section
7.3.2 Zero Calibration Shift
for more information.
7.3 Trouble Shooting Calibration
This section is intended to aid in correcting issues that may arise during the calibration procedure.
