4. With the desired alarm set points appearing on the dis-

play, press the SELECT button until no digits are flashing

on the display. The alarm settings will be saved.

Note: While in the alarm setting mode, if no button is

pressed for fifteen (15) seconds, the unit automatically

exits from the setting mode. All digits will stop flashing to

indicate setting mode has been exited.

VIEWING THE TEMPERATURE ALARM LIMITS

Slide the DISPLAY switch to the ALARM position. The display

will show the current temperature and low/high alarm set

points.
ENABLE/DISABLE ALARMS

To enable the alarm, slide the ALARM switch to the ON

position. When the alarm is enabled, both high and low alarm

set points will be monitored. If the sensor achieves an alarm

condition, the alarm will activate. It is not possible to enable

the alarm for one set point and disable the alarm for the other

set point.

To disable the alarm so that no alarm sounds when a

temperature measured is outside the alarm limits, slide the

ALARM switch to the OFF position.
ALARM SOUNDING

With the alarm enabled, the unit will sound an alarm, the cor-

responding alarm LCD segment will flash, and the red LEDs

will flash when a temperature being measured is outside

the alarm limits that have been set (equal to or lower than

the low alarm set point, or equal to or greater than the high

alarm set point). Until it has been acknowledged/silenced

(see the “Acknowledge/Silence An Alarm” section), the alarm

will sound, the LCD will flash, and the red LEDs will flash

continuously for the first sixty (60) seconds. After 60 seconds,

the alarm will sound and LEDs will flash for ten (10) seconds

each minute. The LCD will flash continuously.
If the alarm is sounding based on the low alarm limit, “LO

ALM” will flash on the display. If the alarm is sounding based

on the high alarm limit, “HI ALM” will flash on the display.
The unit will continue to alarm, flash red LEDs, and flash

the LCD until the alarm has been acknowledged/silenced by

either pressing the SILENCE ALM button or by sliding the

ALARM switch to the OFF position (see the “Acknowledge/

Silence An Alarm” section). The unit will continue to alarm

even if the temperature being measured returns to an in-

range/non-alarm condition.
ACKNOWLEDGE/SILENCE AN ALARM

While alarming, the alarm may be acknowledged/silenced in

one of the following ways:

1. Slide the ALARM switch to the OFF position.

Setting the ALARM switch to the OFF position will silence

the alarm, but when it is switched back to the ON position,

if the temperature being measured is still in an alarm

condition, the alarm will sound.

2. Press the SILENCE ALM button. The alarm will not sound

again until the temperature being measured has returned

to an in-range condition and then goes to an alarm

condition.

VIEWING ALARM EVENT VALUE DATE & TIME

When the thermometer achieves an alarm condition, the date

and time for the most recent alarm condition is stored into

memory. To view the most recent alarm event:

1. Slide the ‘DISPLAY’ switch to the ‘ALARM’ position.

The display will show the current temperature and the

low/high alarm set values.

2. Press the ‘EVENT DATE/TIME’ button. The most recent

alarm set value that was achieved along with the time-of-

day/date the alarm occurred will appear on the display.

Note: The value that appears at the top of the display

while displaying the event date/time, is the alarm set

value that caused the alarm condition, not the actual

temperature achieved while in the alarm condition. If an

alarm has not yet been triggered, pressing the ‘EVENT

DATE/TIME’ button, will display LL.LL. This indicates that

either the unit has not achieved an alarm condition, or that

the alarm set values have been changed since the unit

last achieved an alarm condition.

3. To exit from the alarm event display mode, press and

release the ‘EVENT DATE/TIME’ button, or simply do not

press any button for fifteen (15) seconds.

EXAMPLE - USING THE ALARM AND MEMORY TO

MONITOR A REFRIGERATOR/FREEZER

The following is a simple example of how to use the alarm

and memory to monitor the temperature inside a refrigerator

or freezer. This example is provided only as a helpful guide

and is not intended to replace existing facility requirements

or procedures.
In this example, the refrigerator temperature must be moni-

tored and logged for each 24 hour period and certain actions

must be taken if temperature falls below 0°C or rises above

5°C at any time during the 24 hour period.
Unit Setup Example

1. Plug the probe into the unit.

2. Install the batteries.

3. Place the probe sensor inside the refrigerator.

4. Place the display outside the refrigerator.

At this point, if using a bottle probe, allow sufficient time

for the bottle probe to reach equilibrium with the current

temperature inside the refrigerator.

5. Set the probe temperature low alarm limit to 0°C. (See

the “Setting The Temperature Alarm Limits” section.)

6. Set the probe temperature high alarm limit to 5°C. (See

the “Setting The Temperature Alarm Limits” section.)

7. Enable the alarms.

(See the “Enable/Disable Alarms” section.)

8. Clear the minimum and maximum memory.

(See the “Clearing the Minimum/Maximum Memory”

section.)

9. Slide the DISPLAY switch to the MIN/MAX position. (See

the “To View Min/Max Memory” section.)

The alarm limits have been set and the alarm has been

enabled. The display has been set to show the current

temperature AND the minimum and maximum temperatures

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 activate. The memory will provide a record of the single

lowest and highest temperature achieved.
DISPLAY MESSAGES

If no buttons are pressed and LL.LL appears on the display,

this indicates that the temperature being measured is outside

of the temperature range of the unit, or that the probe is

disconnected or damaged.
BENCH STAND

The unit is supplied with a bench stand located on the back.

To use the bench stand, locate the small opening at the

bottom back of the unit. Place your fingernail into the opening

and flip the stand out. To close the stand, simply snap it shut.
ALL OPERATIONAL DIFFICULTIES

If this unit does not function properly for any reason, replace

the batteries with new high-quality batteries (see the “Battery

Replacement” section). Low battery power can occasionally

cause any number of “apparent” operational difficulties.

Replacing the batteries with new fresh batteries 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 batteries must be replaced. Remove the battery cover,

located on the back of the unit, by sliding it down. Remove

the exhausted batteries and replace them with two (2) new

AAA alkaline batteries. Insert the new batteries with the

proper polarity as indicated by the illustration in the battery

compartment. Replace the battery cover.
Replacing the batteries will clear the minimum/maximum

memories, the high/low alarm settings, and the time-of- day/

date.
