sensor

When receiving a new microsensor remove the shock-absorbing 
grey plastic net . 

Please do not remove the seal and protective 

tube before the following steps are successfully completed.

Connect the Unisense temperature microsensor to the input 
terminal of the T301 or the Microsensor Multimeter or Monometer .

Without calibration, the Unisense temperature sensor in 
combination with the Unisense T301 thermometer has a precision 
of ±1

o

C . To verify the function and/or to achieve an even better 

precision (down to ±0 .1 

o

C), perform the following calibration 

procedure: Prepare two solutions with well defined temperature, 
one slightly above and one slightly below the temperature range 
in which the measurements are expected to be performed . 
To ensure that the calibration temperatures are well-defined, 
use for instance boiling water versus ice-water, or monitor the 
temperature of the solutions with an independent thermometer 
with a better precision than 1

o

C . 

Microsensor Multimeter/Monometer: Perform the calibrations in 
the software . Please consult the relevant software manual . 

T301: If the display of the T301 deviates from the independent 
thermometer, you can correct subsequent measurements by 
adding the difference to the display value .
 

WARNING

Do not remove 

seal and protective 

plastic tube before 

the following steps  

are successfully 

completed.

The Unisense T301 thermocouple 

meter which is used for the TP-MR and 

TP200 temperature microsensors.
