Microx TX3 

Operation 

 

The temperature for temperature compensated measurement is displayed either “on-line”, if 
the temperature sensor is connected, or “off-line”, if the temperature sensor is not connected. 
 
In the upper right corner warning lights are displayed showing possible errors of the raw data 
(amplitude, phase, ambient light). 
 

 amplitude:  

green: The amplitude is correct. 

 

 

yellow: The amplitude is critically low; replacement of the sensor is  

recommended. 

red: 

The amplitude is too low; the sensor tip may be damaged or 
the sensor cable may not be connected. 

  phase:  

green:  The phase angle is within the normal range. 
red: 

The phase angle is out of limits. 

  ambient light:  green: The ratio of sensor signal to ambient light is acceptable. 

red: 

The level of background light (e. g. direct sunlight, lamps) is too 
high. Reduction of ambient light is recommended.
