PROBES
4048 Model Probe: A detachable probe sensor and ten feet of cable are supplied with
the unit. A wire probe holder is provided for permanently mounting
the probe. To mount the probe, place a nail or screw through the
hole of the wireholder and secure the holder to a surface.
4127 Model Probe: Probe is sealed in a miniature bottle (1 x 2½ inches) filled with a
patented nontoxic glycol. Solution is GRAS (generally recognized
as safe) by the FDA (Food and Drug Administration). It eliminates
concerns about incidental contact with food or drinking water. The
solution filled bottle simulates the temperature of other stored
liquids. Velcro ® and magnetic strip are supplied to mount the bottle
to the inside of a refrigerator/ freezer and to mount the display unit
to the outside. Micro-cable permits refrigerator doors to close on it.
NOTE: Plug probe sensor into the jack on the side of the unit. Press RESET button once
whenever probe sensor is removed or inserted. Updated ambient or probe temperatures will
be displayed.
With probe sensor attached the unit simultaneously displays current probe temperature and
probe minimum/maximum temperatures.
With the probe sensor removed the unit simultaneously displays current ambient tempera-
ture and ambient minimum/maximum temperatures.
RESETTING THE UNIT
Use a pointed object to push the RESET button on the back of the unit. It is necessary to
reset the unit whenever a change is made to o C/ o F temperature , FAST/NORMAL sampling
rate, or the probe sensor is plugged in or removed.
NOTE: HI/LO temperature alarm settings and MIN/MAX memories will be cleared after
resetting the unit.
OPERATION MODES
The unit has two operating modes: NORMAL DISPLAY MODE and ALARM DISPLAY
MODE. To change from one mode to another press the MODE button once.
NORMAL DISPLAY MODE Indicated by the display of current temperature and the
MIN (minimum) and MAX (maximum) temperatures. These
temperatures relate to external (probe) temperature if the
probe is plugged in and to internal (ambient) temperature if
the sensor probe is removed.
ALARM DISPLAY MODE Indicated by the display of current temperature and the HI
and LO alarm settings. These temperatures relate to external
(probe) temperature if the probe is plugged in and to internal
(ambient) temperature if the sensor probe is removed.
RESETTING MIN/MAX MEMORIES
There are two ways to reset the memories:
1. To reset both minimum and maximum memories - press MEMORY CLEAR button.
2. To reset individual minimum and maximum memories - press either the MIN or MAX
button (on back of unit) once to reset the respective memory. The other memory will
remain unaffected.
NOTE: You must be in Normal Display Mode to reset the memories.
DISPLAYING °F OR °C
To display the temperature readings in Fahrenheit (°F) or Celsius (°C) slide the switch on
the back of the unit to °F or °C.
NOTE: The unit must be reset after changing the temperature unit.
SELECTING THE SAMPLING RATE
To select normal sampling rate (60 seconds) or fast sampling rate (10 seconds) slide the
switch on back of unit to NORMAL or FAST.
NOTE: The unit must be reset after changing the sampling rate. Using the NORMAL
sampling rate will extend battery life.
SETTING THE HIGH/LOW ALARM
1. Press the MODE button until unit is in the ALARM DISPLAY MODE indicated by the
display of current temperature and HI and LO alarm settings.
2. To set the HIGH temperature alarm limit press the HI button, to advance the display in
1° increments, until the desired high temperature is displayed. Press and hold the HI
button to rapidly advance the display in 5° increments.
3. To set the LOW temperature alarm limit press the LO button, to advance the display in
1° increments, until the desired low temperature is displayed. Press and hold the LO
button to rapidly advance the display in 5° increments.
ALARM
The unit will sound the alarm in both NORMAL DISPLAY MODE and ALARM DISPLAY
MODE.
Slide the ALARM ON/OFF switch to ON. When the current temperature display rises
above the HI set point, or falls below the LO set point, the alarm will sound for 1 minute
and issue a 3 second repeater beep every minute thereafter, for up to 12 hours. The
alarm will continue to sound even if the current temperature display returns to an “in
range” condition.
To temporarily silence the alarm press either the HI or LO button the back of the unit.
The unit is still active and the alarm will sound again if the temperature goes out of range.
To permanently silence the alarm slide the ALARM ON/OFF switch to OFF position.
BENCH STAND
The unit is supplied with a bench stand that is a part of the battery cover. To use the
bench stand, locate the small rectangular opening at the bottom of the unit. Place your
fingernail into the opening and flip the stand up. To close the stand, simply snap it shut.
WALL MOUNTING THE UNIT
Set a screw into the wall at the desired location. Do not set the screw flush to the wall,
the head of the screw will need to slip into the receptacle on the back of the unit. Once
the screw has been properly set, hang the unit in place by sliding the receptacle on the
back of the unit over the head of the screw.
ALL OPERATIONAL DIFFICULTIES
If this thermometer does not function properly for any reason, please replace the battery
with a new high-quality battery (see “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. If the voltage of the battery
becomes low °C and °F symbols will flash.
BATTERY REPLACEMENT
Erratic readings, a faint display, or no display are all indications that the battery must be
replaced. Slide the battery cover toward the end of the unit. Remove the exhausted bat-
tery and replace with an AA alkaline battery (Cat. No. 1111). Replace the battery cover.
