6.2.  Troubleshooting Other Symptoms and Solutions 

The following section describes the most common symptoms that are likely to occur with 
the AeroNOx 2.0  and suggests the possible solutions. 

SYMPTOMS AND SOLUTIONS 

1. 

Instrument has been sitting for some time.  It has not been connected to a charger and the 
power switch does not turn the instrument on.  The sample pump does not run. 

Possible solutions: 

1. 

The battery is disconnected, or has become discharged.  
Connect charger, cycle power, and see if proper operation 
now occurs.  Recharge battery for at least 7 hours. 

2. 

The unit has been subjected to a severe ESD occurrence.  
Disconnect the AC power supply and remove and disconnect 
battery for a few seconds.  Reconnect battery and check 
operation. 

3. 

Replace battery if it fails to charge. 

2. 

Instrument has been sitting for some time.  It has not been connected to a charger.  When 
charger was connected and the unit turned on, very high NO values are indicated on the LCD 
and the alarms are sounding. 

Possible solutions: 

1. 

The battery has become deeply discharged and the 
instrument has been unable to maintain the bias voltage on 
the NO sensor.  Connect charger and allow battery to charge 
and the instrument to bias the NO sensor for at least 48 hours 
before attempting to calibrate the instrument and take 
measurements. 

2. 

If battery fails to take a charge, replace the battery. 

3. 

Oxygen analyzer will not calibrate to room air of 21% O

2

. 

Possible solution: 

1. 

Check the output of the O

2

 sensor for approximately 10 mV 

output in room air.  If < 9 mV, replace sensor. 

2. 

Check cable and connectors connecting the sensor to the 
circuit board. 

4. 

Oxygen analyzer will not calibrate to 100% O

2

. 

Possible solutions: 

1. 

Check the output of the O

2

 sensor for approximately 10 mV 

output in room air.  If < 9 mV, replace sensor.  13 mV is 
expected at 100% O

2

. 

2. 

If sensor checks OK above, check plumbing, tubing, and 
connections for leaks in the system.  Ambient air is probably 
being drawn into the system.  Repair leaks. 

3. 

Check cable and connectors connecting the sensor to the 
circuit board.
