PROBE INSTALLATION
Plug probe sensors into jacks on side of unit, then
slide probe channel switch to desired channel.
With probe sensor attached, unit displays current
probe temperature & probe MIN/MAX temperatures.
With the probe sensor removed unit displays “--.-”.
PROBES
Model 4730/4731-- Supplied with 1 bottle probe
(4730) or 2 bottle probes (4731), designed for use
in refrigerators and freezers. Bottle probes are lled
with a patented nontoxic glycol solution that is GRAS
ALARM DISPLAY MODE - is indicated by the display
of current temperature and the HI and LO alarm settings. These values corresponds to the probe channel
selected by the probe switch.
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 MIN/MAX Display Mode to
reset the memories.
(Generally Recognized As Safe) by the FDA (Food
and Drug Administration) eliminating concerns about
incidental contact with food or drinking water.
The solution lled bottle simulates the temperature
of other stored liquids. Velcro
®
and a magnetic strip
are provided to mount the bottle inside a refrigerator/
freezer. The included micro-thin probe cable permits
refrigerator/freezer doors to close on it. (Do not immerse bottle probes in liquid).
Model 4732 / 4733-- Supplied with standard plastic
probe with cable. Designed for use in air and liquids,
the sensor and cable may be completely immersed.
Model 4734– Supplied with 1 bottle probe with cable
and 1 standard plastic probe with cable.
Model 4735 / 4736– Supplied with 1, 5ml vaccine
bottle probe (4735) or 2, 5ml vaccine bottle probes
(4736). Designed to t in vaccine trays.
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.
RESETTING THE UNIT
Use a pointed object to push the RESET button on the
back of unit.
NOTE: HI/LO temperature alarm settings and MIN/
MAX memories will be cleared after resetting the unit.
DISPLAY MODES
The unit has two display modes: MIN/MAX DISPLAY
MODE and ALARM DISPLAY MODE. To change from
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.
SETTING THE HIGH/LOW ALARM
1. Press the MODE button until the 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 on the back of unit to increment the limit in
0.1° intervals; press and hold to increment the limit
in 1° intervals.
3. To set the LOW temperature alarm limit press the
LO button on the back of unit to increment in 0.1°
intervals; press and hold to increment the limit in 1°
intervals.
ALARM
The unit will sound the alarm in both MIN/MAX DISPLAY MODE and ALARM DISPLAY MODE.
Note: The alarm limits cannot be changed while an
alarm is active.
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. The alarm will continue
to sound even if the current temperature display re-
turns to an “in range” condition and the LCD will ash.
one mode to the other press the MODE button once.
MIN/MAX DISPLAY MODE - is indicated by the display
of current temperature and the MIN (minimum) and
MAX (maximum) temperatures. These values correspond to the probe channel selected with the probe
switch.
ALARM OPERATION
1. To clear the active alarm, press the Memory Clear
button or slide the Alarm switch to the OFF position.
While in ALARM DISPLAY MODE, pressing either
the MIN/LO or MAX/HI button will also clear the
alarm.
2. Alarm conditions will remain active until cleared,
even if the temperature value returns to with the
alarm limits.
3. The alarm limits cannot be changed while an alarm
is active.
VIEWING THE TEMPERATURE ALARM LIMITS
1. While in the ALARM DISPLAY MODE, slide the
PROBE switch to the desired position (1 or 2) to
display the temperature sensor readings.
2. Display will show the current temperature and
low/high alarm set points for the selected probe.
ENABLE/DISABLE ALARMS
To enable the alarm function, slide the ALARM
switch to the ON position.
When the alarm is enabled, both Probe 1 and Probe
2 alarm channels will be monitored. If either sensor
enters an alarm condition, the alarm will activate. It
is not possible to enable the alarm for one sensor
and disable the alarm for the other sensor.
A disconnected probe does not trigger an alarm
state.
To disable the alarm function, slide the ALARM
switch to the OFF position.
ALARM SOUNDING
With the alarm enabled an alarm will sound and
the LCD will ash when a temperature is measured
outside the alarm limits that have been set. Until it
has been acknowledged/silenced (see the “Alarm
operation” section), the alarm will sound and the
corresponding LCD set point breached will ash
continuously for the rst sixty (60) seconds. After
60 seconds, the alarm will sound for three (3)
seconds every minute.
The unit will continue to alarm and ash the
corresponding LCD set point until the alarm has been
acknowledged/silenced.
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 ngernail into the opening and ip 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 ush 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 highquality battery (see “Battery Replacement” section).
Low battery power can occasionally cause any number
of “apparent” operational difculties. Replacing the battery with a new fresh battery will solve most difculties.
BATTERY REPLACEMENT
Low battery symbol, 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 batteries and replace with
2 AAA batteries. Replace the battery cover.
STATIC SUPPRESSOR INSTALLATION
Static generated, radio frequency can affect any cable
through the air or by physical contact. To protect against
radio frequency, install a suppressor onto your thermometers cable to absorb radio frequency as follows:
Lay the cable along the center of the
suppressor with the connector to your left.
Loop the right end of the cable under the
suppressor and back up again laying the cable along
the center of the suppressor.
