Test To Check Correct Pin Probe Insertion
•
Set-temperature cycles are preceded by a test step in order to check correct
pin probe insertion.
•
If power is interrupted during the test, when power is restored, the test will
start again from the beginning.
The test has two stages:
•
if the outcome of the first stage is positive, the second will not be run
•
if the outcome of the first stage is negative, the second will be run.
•
The outcome of the first stage is positive if "the temperature measured by the pin probe - the
temperature of the cabinet" is greater than the value set by parameter rc at least 3 times out of 5 (the
comparison is made every 10 s); if parameter rc is set to 0, neither the first nor second stages will be
run.
•
The outcome of the second stage is positive if the difference "temperature measured by the pin probe
- temperature of the cabinet" is greater by at least 1ºC/1ºF (with respect to the previous comparison)
at least 6 times out of 8 (the comparison is made every "rd/8 s")
If the outcome of the test is positive:
•
the cycle will be activated
•
the cycle will be started in timed mode
•
the LED
