During storage:
• the display shows the cabinet temperature
• if chilling had a positive outcome, the LEDs
and
will be on; if
chilling had a negative outcome, the LEDs
and
will be on and the
LED
will flash.
• the parameter rA sets the operational set point
• press
several times to:
- display the message “nEg”
- exit the procedure, or leave for 15 seconds
To interrupt the
cycle:
• press
for 2 seconds
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
will flash
Setting The Configuration Parameters
The parameters are arranged on two levels.
To access the first
level:
• ensure the device is in “stand-by” mode and no procedures are running
• press
and
for 4 s: the display will show “PA”
To access the
second level:
• access the first level
• press
or
to select “PA”
• press
• press
or
within 15 s to set “-19”
• press
or leave for 15 s
• press
and
for 4 s: the display will show “CA1”
