DIGITAL/TRACEABLE
THERMOMETER INSTRUCTIONS
SPECIFICATIONS
Range: -58.0 to 158.0 °F / -50.0 to 70.0 °C
Resolution: 0.1°
Update Rate: 10 seconds
Battery: AAA (1.5V)
Probe Supplied:
Model 4227 - Supplied with a bottle sensor and cable. Bottle sensor is filled
with a patented non toxic glycol solution that is GRAS (Generally Recognized
As Safe) by the FDA (Food and Drug Administration) eliminating concerns
about incidental contact with food or drinking water. The solution filled bottle
simulates the temperature of other stored liquids. Velcro® and a magnetic
strip are provided to mount the bottle to the inside of a refrigerator/freezer and
to mount the display on the outside. The micro-thin probe cable permits
refrigerator/freezer doors to close on it.
TEMPERATURE DISPLAY MODES
Ambient Temperature Display Mode (IN):
Indicated by “IN” appearing on the display, displays the current ambient
temperature and either the ambient temperature memory (MIN/MAX) or the
ambient temperature alarm limits (LO/HI). For the purpose of temperature
monitoring there is no requirement to display the ‘IN’ Mode
Probe Temperature Display Mode (OUT):
Indicated by “OUT” appearing on the display, the current probe temperature
and either the probe temperature memory (MIN/MAX) or the probe
temperature alarm limits (LO/HI). The ‘OUT’ Mode is the screen that is
used to record temperature monitoring. Please ensure that this screen
is displayed at all times.
To change between ambient (IN) and probe (OUT) temperature display
modes, press the IN/OUT button located on the back of the unit. Please
ensure that the ‘OUT’ screen is displayed at all times ,
DISPLAYING °F OR °C
To display the temperature readings in Fahrenheit or Celsius, press the °C/°F
button located on the back of the unit. Temperature montoring should
always be recorded in Celsius -°C.

ALARM SOUNDING
With the alarm enabled (a bell logo on current screen situated on the top left),
the unit will sound an alarm when the temperature being displayed is outside
the alarm limits that have been set for that display mode (equal to or lower
than the low alarm set point, or equal to or greater than the high alarm set
point).
If the alarm is sounding based on the low alarm limit e.g. 20C, “LO” will flash
on the display.
If the alarm is sounding based on the high alarm limit e.g. 80C, “HI” will flash
on the display.
The unit will continue to alarm and flash the corresponding “LO” or “HI” until
the temperature being displayed is within the alarm limits. Once the
temperature being displayed is within the alarm limits, the alarm will stop
sounding and the corresponding “LO” or “HI” will no longer flash.
To silence an alarm manually, press either the minimum or maximum button
once. When manually silenced, the corresponding “LO” or “HI” will continue to
flash on the display until the temperature is within the alarm limits. For
temperatures out with set limits see guidance on page 1, section 6.
To check the alarm settings press the MODE button once. The alarm settings
must be set at 20C LOW and 80C HI. Please ensure the MODE button is
pressed once again to return to normal display settings.
RESET BUTTON
The RESET button located on the back of the unit must not be pressed. If
there are any problems with the thermometer please contact Vaccine
Services staff who will advise.
ON/OFF BUTTON
The ON/OFF button located on the back of the unit may be used to turn the
unit off when the thermometer is not being used. The minimum/ maximum
memory and alarm limits are not cleared when the unit is turned off. To turn
the unit off,
press the ON/OFF button. Each successive press of the ON/OFF button will
turn the unit on or off.
No alarms will sound and no minimum/maximum memory will be
recorded when the unit is off.
MAGNET ATTACHEMENT
Vaccine Services advise that the magnet be attached to the back of the unit
and placed on top or on the side of the fridge. There is no need for the
thermometer to be moved whilst recording the temperature as all
temperatures are displayed on the front. This also avoids inadvertently
pressing any of the blue settings on the back.

QUICK GUIDE THERMOMETER SET UP
1. Plug the probe (green bottle attachment) into the side of the unit.
2. Install the battery into the back of the unit.
3. Place the probe sensor (green glycol bottle) in the middle of the
refrigerator
4. Place the display unit outside the refrigerator using the magnet
supplied
5. Allow sufficient time (approximately 1 hour) before switching the
thermometer unit on using the on/off button at the back of the unit.
This allows the green glycol probe to equilibrate.
6. To set the alarm limits- Press ‘Mode’ until LO/HI appears on bottom
section of screen.
7. Press ‘MIN’ continuously and the minimum alarm setting will change.
Continue until it reaches 2.0°C.
8. Press ‘MAX’ continuously and the maximum alarm setting will change.
Continue until it reaches 8.0°C.
9. Press ‘Mode’ and this display will change to LO/HI.
10. The current temperature is now displayed along with MIN/MAX in each
box. The alarm bell logo will now be displayed on the screen. If the
alarm bell logo is not displayed turn the unit over and press the alarm
button.
11. The display unit is now ready for use. NB Always ensure that the ‘OUT’
mode is displayed on the screen.
The alarm limits have been set and the alarm has been enabled. The display
has been set to show the current temperature inside the refrigerator along
with the minimum and maximum temperature that has been 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 sound. If no one is available to hear the alarm
sounding (overnight), and the temperature returns to an in range condition,
the memory will provide a record of the single lowest and highest temperature
achieved. When the temperatures are recorded into the manual log, the
memory will allow the user to see that the temperature inside the refrigerator
had gone outside of the acceptable range.
Clearing Alarm Recording
After each recording the unit must be reset.
•Ensure unit is displaying LO/HI
•Press ‘MIN’ once to reset minimum temperature
•Press ‘MAX’ once to reset maximum temperature
Monitoring Procedure Example
Keep a notebook or spreadsheet as a manual log.
1. At the same time every day, record the following into the manual log:
• Current Date and Time
• Current Temperature Reading

• Minimum Temperature Reading (MIN)
• Maximum Temperature Reading (MAX)
2. Once the above items have been manually recorded, clear both the
minimum and maximum temperature memory.
By clearing the memory each day, the minimum and maximum temperature
memory will provide a record of the minimum and maximum temperature that
has been achieved inside the refrigerator over the past 24 hour monitoring
period. The memory will also allow the user to see if the temperature inside
the refrigerator went outside of the acceptable range when there was no one
available to hear the alarm (overnight).
ALL OPERATIONAL DIFFICULTIES
If this unit does not function properly for any reason, replace the battery with a
new high-quality battery (see the “Battery Replacement” section). Low battery
power can occasionally cause any number of “apparent” operational
difficulties. Replacing the battery with a new fresh battery 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 battery must be replaced. Open the
battery compartment by depressing the tab located at the top of the battery
cover and
lifting it out. The battery cover is hinged at the bottom so that the battery
compartment may be opened without completely removing the battery cover.
Remove the exhausted battery and replace with a AAA alkaline battery. Make
certain to insert the new battery with the proper polarity as indicated in the
illustration in the battery compartment.
Close the battery cover. Replacing the battery has the same affect as
pressing the RESET button. (See the “RESET BUTTON” section.)
