The calibrator's switch test procedure
1. Once the switch test is started, the calibrator starts working towards
T
1
as quickly as possible. The calibrator's temperature changes
(heating or cooling) and switch status are shown in the display.
2. When T
1
is achieved and the temperature is stable, the text and the
graphic in the middle of the screen will change accordingly.
3. The calibrator now starts working towards T
2
at the specified slope
rate.
4. In a normal situation, the thermostat changes state before T
2
is
achieved. If T
2
is achieved and the temperature is stable, a red
cross will be displayed instead of a green check .
5. When hysteresis is not selected (single temperature change) (the
graphic indicates the choice), the finished switch test result is
displayed.
When hysteresis is selected (two switch changes), the calibrator
starts working towards T
1
at the specified slope rate.
6. Normally, the thermostat changes state before T
1
is achieved. If T
1
is reached and the temperature is stable, a red cross will be
displayed instead of a green check .
7. The finished switch test results are displayed.
4.8.2 Showing switch test results
Two types of switch test results are available:
Results during a switch test.
Results of a finished switch test.
