Lab Advisor Thermostat Test

This Information Applies To: Lab Advisor software - Agilent G 7116A/B Multicolumn Thermostat (MCT) modules

Issue:

The Lab Advisor Thermostat test is a rapid test that evaluates the cooling and heating performance of the two Peltier elements in your MCT module.

The test is run using Lab Advisor's Service and Diagnostic Test section (see Figure 1). Example is for an Agilent 1290 MCT module (G7116B). 

Figure 1. Lab Advisor - Thermostat test.

The test proceeds as follows automatically:

1. The Lab Advisor Thermostat test starts by setting the temperature of the Peltier elements to the same as the ambient temperature.
2. The temperature is reduced to 4 °C and the cooling performance is evaluated.
3. The temperature is reset to the starting temperature and the heating performance is evaluated.
4. The result of the test is displayed.

Steps to follow:

1. To start the test, click Run on the bottom right of the screen. The test is automatic and it does not need the help of an operator while running.
2. While the test is running, the screen shows the test progress. It normally completes in approximately 5 minutes.
3. Click Abort to interrupt the test before completion, if needed.
4. At the end of the test, Lab Advisor shows a passed or failed result.
5. It is possible to obtain information about temperature limits used and cooling/heating signals obtained, by switching tabs of the results page (General, Limits, Signals).
6. A PDF file containing result and details of the test can be generated clicking Print Result on the bottom right of the results screen (see Figure 2).
