The first time to zero is 15 minutes. After that the time to zero is 30 minutes.
The analyzer will beep 3 times one minute before a fresh air zeroing is required
and then after a further minute beep continuously.
The bottom line of the display shows time, date and battery level.
When a zero is required the top left hand corner of the display will show “ZERO
REQUIRED”. Press the
key to initiate zeroing. When zeroing always
ensure that the analyzer is sampling fresh air
The analyzer is now ready for use.
NOTE: The backlight comes on automatically whenever a button is pressed
and then switches off after about 30 seconds.
TIP: It has been found that in most workshops there is a background level
of HC due to oil permeation of the floor. For true fresh air you need to
be sampling outside the workshop or at least 2 meters above the floor.
Notes:
1) Lambda can be replaced by AFR as described below.
2) If AUTOLOG is active then the log time will be displayed at the top right
hand side of the screen
3) If the charger is connected then the display will show the Battery icon filling
up.
