PROBES
Model 10050-584 (620-2334)/10050-586 (620-2335)-- Supplied with 1 bottle probe (10050-584 (620-
2334)) or 2 bottle probes (10050-586 (620-2335)), designed for use in refrigerators and freezers.
Bottle probes are filled 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 filled 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 10050-588 (620-2336) / 10050-590 (620-2337)-- Supplied with standard plastic probe with
cable. Designed for use in air and liquids, the sensor and cable may be completely immersed.
Model 10050-592 (620-2338)– Supplied with 1 bottle probe with cable and 1 standard plastic probe
with cable.
Model 10050-594 (620-2339) / 10050-596 (620-2340)– Supplied with 1, 5ml vaccine bottle probe
(10050-594 (620-2339)) or 2, 5ml vaccine bottle probes (10050-596 (620-2340)). Designed to fit 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 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 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:
VWR Collection Manual ver 1, rel 1 20.02.2017
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.
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
returns to an “in range” condition and the LCD will flash.
ALARM OPERATION
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.
Alarm conditions will remain active until cleared, even if the temperature value returns to with the
alarm limits.
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.
VWR Collection Manual ver 1, rel 1 20.02.2017
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 flash 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 flash
continuously for the first sixty (60) seconds. After 60 seconds, the alarm will sound for three (3)
seconds every minute.
The unit will continue to alarm and flash 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 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.
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
VWR Collection Manual ver 1, rel 1 20.02.2017
frequency as follows:
1. Lay the cable along the center of the suppressor with the connector to your left.
2. Loop the right end of the cable under the suppressor and back up again laying the cable
along the center of the suppressor.
3. Carefully, snap the two halves together with the looped cable routed through the center.
4. This completes the installation of the suppressor.
