Manual for a description of the operational modes.
• BH Measuring Time: The BH Measuring Time parameter only applies to
instruments being used in Bar Hole Mode. The BH Measuring Time is the
amount of time the unit samples the bar hole. It can be set to 30 (factory setting),
45, or 60 seconds. Use the up and down arrow buttons to make your selection.
• Peak Bar Display: If Peak Bar Display is selected, the peak bar appears along
the left side of the screen during Normal Operation and on the Peak Screen in
Display Mode. It shows the peak readings for each channel in bar graph format.
If Peak Bar Display is not selected (factory setting), the peak bar will not appear
during Normal Operation or in the Peak Screen in Display Mode.
• Confirmation Beep: If Confirmation Beep is selected, the instrument confirms it
is still operating by beeping every 5 minutes. If Confirmation Beep is not
selected (factory setting), the instrument will not beep.
• Leak Check Buzzer: If selected (factory setting), the buzzer will operate in Leak
Check Mode. This setting only applies to Gas Tracers.
• Leak Check Auto ppm: If Leak Check Auto ppm is selected (factory setting), if
the ppm sensor encounters an overscale gas condition while in Leak Check
Mode, the instrument will automatically begin measuring combustible gas with
the catalytic LEL sensor. If Leak Check Auto ppm is not selected, the ppm
sensor will automatically shut off and enter a warm up period if it encounters an
overscale gas condition.
