3. Enter the exact value of the attached resistor and press 

 to save the 

offset.

4. Press 

 to return to the Permeation Oven menu.

5. Remove the resistor and re-attach the permeation oven to POJ3.

Setting Temperature with Water

Bath

Use the following procedure for setting the measure temperature with water 
bath.

1. Remove the thermistor from the permeation tube oven, but leave the 

thermistor connected to the measurement interface board. Insert the 
thermistor into the water bath next to an NIST traceable thermometer 
(if necessary, use an extension cable to reach).

2. Turn on the power to the water bath. Using an NIST traceable 

thermometer with a resolution of 

±

0.01 

°

C, adjust the water bath 

to 45 

°

C.
