3.6
Test for checking that the needle probe is inserted correctly
Before running a temperature controlled chilling cycle a test is run to check that the
needle probe has been inserted correctly.
The test is divided into two steps:
if the first step is OK, the second step is ignored
if the first step results negative, the second step is performed.
The first step results positive when at least for 3 out of 5 times the difference in
“the temperature detected by the needle probe - chiller temperature” results greater
than the parameter rc (this comparison is run every 10 seconds); if the parameter rc
is set at 0, neither the first nor second step of the test are run.
The second step results positive if the difference in “the temperature detected by the
needle probe – chiller temperature” is, at least 6 times out of 8, 1 °C / 1 °F greater
(in respect to the previous comparison)
(this comparison is run every “rd/8 seconds”).
If the test results positive- OK:
the cycle will start running.
If the test results negative:
the cycle will be delayed.

If the power supply is unexpectedly interrupted during testing, when power is
