In  case  of instrument  fault detection,  the device must be  shipped to the manufacturer for 

maintenance. In Table 3.3. Faults that can be fixed by yourself. 

 
Table 3.3 - Possible malfunctions and methods of their elimination 
 

Name of malfunction, 

external manifestation and 

additional signs

 

Probable cause

 

Method of elimination

 

The device does not turn on

 

No power

 

Check the presence and status of 
self-contained power

 

No measurements

 

Break in the probe circuit

 

Check and eliminate the break

 

The instrument displays false 
readings

 

The device is not calibrated or is 
influenced by the influencing 
factors

 

Repeat calibration of the device 
and eliminate the influence of 
external factors
