Control Company 4227 TRACEABLE THERMOMETER - Manual

MINIMUM AND MAXIMUM MEMORY
There are four points that are automatically
recorded into memory:
Minimum (MIN) Ambient Temperature Achieved
Maximum (MAX) Ambient Temperature Achieved
Minimum (MIN) Probe Temperature Achieved
Maximum (MAX) Probe Temperature Achieved
All four memories are independent of each other.
Minimum and maximum temperature memories
are NOT programmable. The minimum temperature
recorded into memory is the minimum temperature
achieved since the last time the memory was
cleared. The maximum temperature recorded into
memory is the maximum temperature achieved
since the last time the memory was cleared. The
minimum and maximum temperature memories are
maintained over the period since the memory was
cleared.
Minimum and maximum memories are recorded for
both ambient and probe temperatures regardless
of the display mode.
CLEARING THE PROBE (OUT) TEMPERATURE
MEMORY
1. Select the Probe Temperature Display Mode by
pressing the IN/OUT button located on the back
of the unit until “OUT” appears on the display.
2. Press the MODE button until “MIN” and “MAX”
appears on the display.
3. Press the MIN-RESET button to clear the
minimum temperature memory. The display
will show “ 88 .8” under MIN and will then display
the new minimum temperature memory.
4. Press the MAX-RESET button to clear the
maximum temperature memory. The display
will show “ 88 .8” under MAX and will then display
the new maximum temperature memory.
CLEARING THE AMBIENT (IN) TEMPERATURE
MEMORY
1. Select the Ambient Temperature Display Mode
by pressing the IN/OUT button located on the
back of the unit until “IN” appears on the display.
2. Press the MODE button until “MIN” and “MAX”
appears on the display.
3. Press the MIN-RESET button to clear the
minimum temperature memory. The display
will show “ 88 .8” under MIN and will then display
the new minimum temperature memory.
4. Press the MAX-RESET button to clear the
maximum temperature memory. The display
will show “ 88 .8” under MAX and will then display
the new maximum temperature memory.
ALARMS
Both ambient (IN) and probe (OUT) temperature
alarm limits may be set in 1° increments.
With the alarm enabled ( ֠ ), 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). Example: If the unit is displaying the
ambient temperature (IN) and the probe
temperature (OUT) is outside the probe temperature
alarm limits, no alarm will sound.
SETTING PROBE (OUT) TEMPERATURE
ALARM LIMITS
1. Select the Probe Temperature Display Mode by
pressing the IN/OUT button located on the back
of the unit until “OUT” appears on the display.
2. Press MODE button until “LO” and “HI” appears.
3. To set the low temperature alarm limit (LO),
press the LO ALM SET button to advance the
display until the desired low temperature is
displayed. Press and hold the LO ALM SET
button to rapidly advance the display.
4. To set the high temperature alarm limit (HI),
press the HI ALM SET button to advance the
display until the desired high temperature is
displayed. Press and hold the HI ALM SET
button to rapidly advance the display.
SETTING AMBIENT (IN) TEMPERATURE
ALARM LIMITS
1. Select the Ambient Temperature Display Mode
by pressing the IN/OUT button located on the
back of the unit until “IN” appears on the display.
2. Press MODE button until “LO” and “HI” appears.
3. To set the low temperature alarm limit (LO),
press the LO ALM SET button to advance the
display until the desired low temperature is
displayed. Press and hold the LO ALM SET
button to rapidly advance the display.
4. To set the high temperature alarm limit (HI),
press the HI ALM SET button to advance the
display until the desired high temperature is
displayed. Press and hold the HI ALM SET
button to rapidly advance the display.
ENABLE/DISABLE ALARMS
To enable the alarm to sound when the temperature
being displayed is outside the alarm limits, press
the
֠ button located on the back of the unit until
“ ֠ ” appears on the display. Each successive
press of the ֠ button will enable ( ֠ ) or disable
the alarm.
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 4727-- Supplied with a standard probe
sensor with cable. Both sensor and cable may be
immersed in liquid. Probe sensor may be mounted
using the supplied sensor holder and mounting
screw.
Model 4227 & 4627-- Supplied with a bottle
sensor and cable. Bottle sensor is fi lled with a
patented nontoxic 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 fi lled 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).
Probe Temperature Display Mode (OUT):
Indicated by “OUT” appearing on the display,
displays the current probe temperature and either
the probe temperature memory (MIN/MAX) or the
probe temperature alarm limits (LO/HI).
To change between ambient (IN) and probe (OUT)
temperature display modes, press the IN/OUT
button located on the back of the unit.
To change between displaying the memory
(MIN/MAX) and the alarm limits (HI/LO), press the
MODE button.
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.
ALARM SOUNDING
With the alarm enabled (
֠ ), 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, “LO” will fl ash on the display. If the
alarm is sounding based on the high alarm limit,
“HI” will fl ash on the display.
The unit will continue to alarm and fl ash 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 fl ash.
To silence an alarm manually, press any button.
When manually silenced, the corresponding “LO”
or “HI” will continue to fl ash on the display until the
temperature is within the alarm limits.
When enabled ( ֠ ), the alarm will only sound if the
temperature being displayed is outside the alarm
limits that have been set for that display mode (IN
or OUT). Example: If the unit is displaying ambient
temperature (IN) and the probe temperature (OUT)
is outside the probe temperature alarm limits, no
alarm will sound.
RESET BUTTON
The RESET button located on the back of the unit
may be used to simultaneously reset the memory
and alarm limits for both the ambient (IN) and
probe (OUT) sensor.
To reset the unit, use a pointed object to press the
RESET button.
When the reset button in pressed, the following will
occur:
• The display will show all segments for
approximately 5 seconds.
• The ambient (IN) and probe (OUT)
minimum/maximum memory will be cleared.
• The ambient (IN) and probe (OUT) alarm
limits will be returned to the factory default
value of 10°C (LO) and 30°C (HI).
• The unit will display the ambient (IN)
temperature in °C.
