is highlighted, double click to choose.
Zero
• During start-up the operator has the option to perform an autozero, or
leave the countdown if an autozero is not required/possible.

needed less than 15 minutes prior to running a manual calibration.

• This function allows the 8 hour TWA to be reviewed.
Pre-Entry Check (PEC)

gaining access to it (e.g. going under ground through a manhole
cover) thereby avoiding unnecessary exposure.

• This function allows the highest level of each gas detected to be
reviewed during the last 8 hours, 12 hours or since turned on.
