14 . If you are using a 5-gas (standard 4-gas + ESS-03) calibration cylinder:
a. Since calibration gas was flowing to the ESS-03 sensor while the standard 4
channels were being calibrated, the ESS-03 sensor reading should be stable and
ready for adjustment.
b. Press and release the POWER/ENTER button to set the span adjustment for the
ESS-03 channel to the programmed value. Continue with Step 15.
15 . If the ESS-03 channel passed calibration, the following screen sequence occurs.
If the ESS-03 channel cannot be adjusted to the proper value, a screen displays that
indicates a calibration failure and indicates that the ESS-03 sensor failed to calibrate.
The buzzer and alarm LEDs activate in a double pulsing pattern. Press and release
the RESET button to reset the alarm and continue to the Auto Cal Menu. Attempt to
calibrate the ESS-03 channel again. If the failure continues, investigate the cause.
