ENTER and use the ARROW key to scroll to Calibrate Span. Press ENTER and
use the ARROW keys in increase or decrease the span gas value.
When the correct value is displayed, attach the regulator to the span gas
cylinder and flow 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 finished 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.
