stabilization period.  The last temperature logged before you removed the logger from the 

unit should be between 2°C and 5°C as with the thermocouple measurement. 

 

Pull out on the front panel toggle switch and change the temperature setting to 

–22°C

.  

After allowing 24 hours for the unit to stabilize, check that your thermometer reads at 

least 

–22°C 

± the accuracy tolerance of your thermometer.  The display on the side of the 

unit should agree within 

2°C

 at this temperature. 

 

Check Indicator Lamps 

 

To test the temperature indicator lamps on the side display, after the unit has been 

stabilized at the 

4°C

 setting, observe that the temperature indicator lamp is GREEN, open 

the lid and remove the dummy load baskets nearest the display end of the unit.  In the 

middle of the tub wall at that end you will see the black temperature sensors protruding 

slightly.  Place your hand over these until the display shows 

6°C

 or higher.  The 

temperature indicator lamp should turn from GREEN to RED within 20 seconds of the 

temperature change. 

 

The battery indicator lamps may be tested by disconnecting the unit from external power 

and allowing the battery to run down.  You may observe the battery voltage on the 

display.  As the battery runs down, the display should change color at the voltages 

indicated in the tables on page 15.  

CAUTION, this test will run the battery down and 

allow the unit to stop.  Never conduct this test with real payload in place or it may 

be ruined.

 

 

To test the temperature setting indicators on the power panel, observe that the lamp is 

correctly lit for your current setting.  Pull out on the temperature setting toggle switch and 

change the setting.  You should see the first lamp go out and the second come on.   

Immediately return the switch to your original setting to avoid affecting the inside 

temperature.
