Autozero Delay
The Scio module is self-zeroing. It automatically initiates zeroing
of its gas sensors against room air about every 2 hours. During
zeroing, the monitor does not update the displayed Scio parame-
ter values on the screen. If zeroing cannot be completed within 25
seconds, the monitor blanks the Scio parameter values and dis-
plays an error message (see the chapter Alarms and Messages).
One minute before the start of zeroing, the monitor sounds an
attention tone (2 beeps) and displays the message Multigas zero
in 1 minute. You can delay zeroing once for a 5-minute period as
follows:
STEPS: Requesting an Autozero Delay
1. In OR mode, click on the O2/N2O/Agent parameter box.
2. Click on
WA RN I N G : Delaying zeroing may compromise the
accuracy of gas values.
NOTE: The menu selection Autozero Delay is only displayed and
available for one minute, just before zeroing starts.
