"LOW MEM"
“LOW MEM” is displayed when the available
memory is not sufficient for six or more hours
of log data.
Notifies the operator to download the log
data to a PC and free up memory space;
if no download is done and memory is
full, then unit will stop logging data and
display “MEM” in upper right corner of
display
Power OFF
The OFF mode is automatically entered when
TDISPLAY ≥TOFF
Enables unit to indicate temperature until
cryogenic chamber temperature warms
up to safer handling temperature (e.g. -
20°C)
Power ON
Power ON can be achieved by a short press
of the power button
on the CryoPod
Carrier.
Unit will stay ON if TDISPLAY ≥
TSTANDBY, otherwise the unit will
automatically switch into “Standby Mode”
after 1 minute
ON Mode
After being powered ON, unit remains in ON
Mode if TDISPLAY ≤ TSTANDBY (Default
TSTANDBY = -100 °C)
ON Mode enables all built-in functionality
(excluding those not enabled by the
operator) such as displays of date/time,
TDISPLAY, alarm on, audible alarm on,
log on, unit ID Code, and battery level
SET Mode

be entered by long pressing the date/time
button
when unit is powered ON
Settable functions include alarms,
date/time, TSTANDBY, and ID Code
Standby Mode
The Standby Mode is automatically entered
when TDISPLAY ≥TSTANDBY.
Enables unit to switch to power saving
Standby Mode while allowing operator to
see TDISPLAY until unit warms to safer
TOFF temperature
TCRITICAL
Temperature setting for Alarm 2.
The TCRITICALis used to alert the
operator that LN
₂
charge is now
insufficient to maintain samples
TDISPLAY
Temperature displayed in large font to the left
side of the LCD screen while unit is in ON
Mode.
TDISPLAY indicates the temperature of
the basket.
TOFF
The unit will automatically power OFF at this
temperature or warmer.
Enables power TOFF conditions such as
no temperature display after TDISPLAY
warms to relatively safer temperature
level of -20°C
TSTANDBY
Temperature setting for automatic switch to
Standby Mode.
When the temperature inside the basket
reaches a temperature warmer than the
TSTANDBY temperature, the system will
switch into Standby Mode.
TWARNING
Temperature setting for Alarm 1.
When the temperature reaches or
exceeds TWARNING to alert the operator
that LN
₂
charge is nearly spent.
