Control Company 6408 PLATINUM HIGH-ACCURACY REFRIGERATOR THERMOMETER - Manual (Page 2)

4. With the desired alarm set points appearing on the dis-
play, press the SELECT button until no digits are flashing
on the display. The alarm settings will be saved.
Note: While in the alarm setting mode, if no button is
pressed for fifteen (15) seconds, the unit automatically
exits from the setting mode. All digits will stop flashing to
indicate setting mode has been exited.
VIEWING THE TEMPERATURE ALARM LIMITS
Slide the DISPLAY switch to the ALARM position. The display
will show the current temperature and low/high alarm set
points.
ENABLE/DISABLE ALARMS
To enable the alarm, slide the ALARM switch to the ON
position. When the alarm is enabled, both high and low alarm
set points will be monitored. If the sensor achieves an alarm
condition, the alarm will activate. It is not possible to enable
the alarm for one set point and disable the alarm for the other
set point.
To disable the alarm so that no alarm sounds when a
temperature measured is outside the alarm limits, slide the
ALARM switch to the OFF position.
ALARM SOUNDING
With the alarm enabled, the unit will sound an alarm, the cor-
responding alarm LCD segment will flash, and the red LEDs
will flash when a temperature being measured is outside
the alarm limits that have been set (equal to or lower than
the low alarm set point, or equal to or greater than the high
alarm set point). Until it has been acknowledged/silenced
(see the “Acknowledge/Silence An Alarm” section), the alarm
will sound, the LCD will flash, and the red LEDs will flash
continuously for the first sixty (60) seconds. After 60 seconds,
the alarm will sound and LEDs will flash for ten (10) seconds
each minute. The LCD will flash continuously.
If the alarm is sounding based on the low alarm limit, “LO
ALM” will flash on the display. If the alarm is sounding based
on the high alarm limit, “HI ALM” will flash on the display.
The unit will continue to alarm, flash red LEDs, and flash
the LCD until the alarm has been acknowledged/silenced by
either pressing the SILENCE ALM button or by sliding the
ALARM switch to the OFF position (see the “Acknowledge/
Silence An Alarm” section). The unit will continue to alarm
even if the temperature being measured returns to an in-
range/non-alarm condition.
ACKNOWLEDGE/SILENCE AN ALARM
While alarming, the alarm may be acknowledged/silenced in
one of the following ways:
1. Slide the ALARM switch to the OFF position.
Setting the ALARM switch to the OFF position will silence
the alarm, but when it is switched back to the ON position,
if the temperature being measured is still in an alarm
condition, the alarm will sound.
2. Press the SILENCE ALM button. The alarm will not sound
again until the temperature being measured has returned
to an in-range condition and then goes to an alarm
condition.
VIEWING ALARM EVENT VALUE DATE & TIME
When the thermometer achieves an alarm condition, the date
and time for the most recent alarm condition is stored into
memory. To view the most recent alarm event:
1. Slide the ‘DISPLAY’ switch to the ‘ALARM’ position.
The display will show the current temperature and the
low/high alarm set values.
2. Press the ‘EVENT DATE/TIME’ button. The most recent
alarm set value that was achieved along with the time-of-
day/date the alarm occurred will appear on the display.
Note: The value that appears at the top of the display
while displaying the event date/time, is the alarm set
value that caused the alarm condition, not the actual
temperature achieved while in the alarm condition. If an
alarm has not yet been triggered, pressing the ‘EVENT
DATE/TIME’ button, will display LL.LL. This indicates that
either the unit has not achieved an alarm condition, or that
the alarm set values have been changed since the unit
last achieved an alarm condition.
3. To exit from the alarm event display mode, press and
release the ‘EVENT DATE/TIME’ button, or simply do not
press any button for fifteen (15) seconds.
EXAMPLE - USING THE ALARM AND MEMORY TO
MONITOR A REFRIGERATOR/FREEZER
The following is a simple example of how to use the alarm
and memory to monitor the temperature inside a refrigerator
or freezer. This example is provided only as a helpful guide
and is not intended to replace existing facility requirements
or procedures.
In this example, the refrigerator temperature must be moni-
tored and logged for each 24 hour period and certain actions
must be taken if temperature falls below 0°C or rises above
5°C at any time during the 24 hour period.
Unit Setup Example
1. Plug the probe into the unit.
2. Install the batteries.
3. Place the probe sensor inside the refrigerator.
4. Place the display outside the refrigerator.
At this point, if using a bottle probe, allow sufficient time
for the bottle probe to reach equilibrium with the current
temperature inside the refrigerator.
5. Set the probe temperature low alarm limit to 0°C. (See
the “Setting The Temperature Alarm Limits” section.)
6. Set the probe temperature high alarm limit to 5°C. (See
the “Setting The Temperature Alarm Limits” section.)
7. Enable the alarms.
(See the “Enable/Disable Alarms” section.)
8. Clear the minimum and maximum memory.
(See the “Clearing the Minimum/Maximum Memory”
section.)
9. Slide the DISPLAY switch to the MIN/MAX position. (See
the “To View Min/Max Memory” section.)
The alarm limits have been set and the alarm has been
enabled. The display has been set to show the current
temperature AND the minimum and maximum temperatures
achieved inside the refrigerator.
If the temperature inside the refrigerator goes outside the
alarm limits (equal to or lower than the low alarm set point, or
equal to or greater than the high alarm set point), the alarm
will activate. The memory will provide a record of the single
lowest and highest temperature achieved.
DISPLAY MESSAGES
If no buttons are pressed and LL.LL appears on the display,
this indicates that the temperature being measured is outside
of the temperature range of the unit, or that the probe is
disconnected or damaged.
BENCH STAND
The unit is supplied with a bench stand located on the back.
To use the bench stand, locate the small opening at the
bottom back of the unit. Place your fingernail into the opening
and flip the stand out. To close the stand, simply snap it shut.
ALL OPERATIONAL DIFFICULTIES
If this unit does not function properly for any reason, replace
the batteries with new high-quality batteries (see the “Battery
Replacement” section). Low battery power can occasionally
cause any number of “apparent” operational difficulties.
Replacing the batteries with new fresh batteries will solve
most difficulties.
BATTERY REPLACEMENT
Erratic readings, a faint display, no display, or a battery
symbol appearing on the display are all indications that
the batteries must be replaced. Remove the battery cover,
located on the back of the unit, by sliding it down. Remove
the exhausted batteries and replace them with two (2) new
AAA alkaline batteries. Insert the new batteries with the
proper polarity as indicated by the illustration in the battery
compartment. Replace the battery cover.
Replacing the batteries will clear the minimum/maximum
memories, the high/low alarm settings, and the time-of- day/
date.
