TROUBLESHOOTING

8 - 10

Problem

Possible Reasons & Solutions

Read a small
background
value

Reasons:

There is actually a small
background gas level Sensor
zero drift

Solutions:

Do fresh air calibration (see

Section 4.4.1)

Reading
jumping
around
randomly

Reasons:

Incorrect calibration gas
value.
Low sensitivity to cal gas

Solutions:

Calibrate the monitor.

Use different cal gas.

Can not turn
off monitor or
corrupted
characters in
LCD display

Reasons:

Microprocessor hang-up

Solutions:

Disconnect and re-connect
battery to reset computer.
Call authorized service
center.

Calibration
error message

Reasons:

No standard gas input, weak
PID lamp, unit zeroed with
gas present

Solutions:

Make sure standard gas flows

into monitor. Zero sensor &
recalibrate, replace lamp.
