TROUBLESHOOTING 

8 - 12 

Problem 

Possible Reasons & Solutions               

Read a small 
background 
value when 
there is no 
detectable 
gas.

 

Reasons:

 

Sensor zero drifted.  
The unit was out of battery 
power connection or the 
sensor just plugged in. 

 

Solutions:

  Do fresh air calibration (see 

Section 4.4.1) 
Wait for reading to stabilized. 
 

Reading 
jumping 
around 
randomly 

Reasons:

 

Incorrect gas calibration. 
Low sensitivity to cal gas. 

 

Solutions:

  Calibrate the sensor. 

                      Use different cal gas. 

 

Cannot 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.  

Solutions:

  Make sure standard gas flows 

into monitor.
