By default, the high and low alarm settings are 8 oC and 2 oC respectively. To reset high alarm and low alarm
temperature settings, follow instructions below.

High Alarm Temperature
Setting

This is the high temperature limit. The current temperature is considered out-of-range if
the probe reads a temperature equal to or above the high temperature limit.

From the main display screen:

Hold the MODE key for 3 seconds to enter High Alarm temperature setting mode. Use the up and
down arrows to adjust temperature accordingly.

Press MODE key ONCE to confirm the setting.

Low Alarm Temperature Setting

This is the low temperature limit. The current temperature is considered out-of-range if
the probe reads a temperature equal to or below the low temperature limit.

From the main display screen:

Hold the MODE key for 3 seconds, then press the Mode key ONCE to enter Low Alarm
temperature setting mode. Use the up and down arrows to adjust temperature accordingly.
Press MODE key ONCE to confirm the settings.

Set the high and low alarm temperature limits above and below the refrigerator/freezer operating temperature to prevent
false alarms. Refrigerators are designed to run between 2-8 °C (36-46 °F) while freezers run below -15 °C (5 °F).

HIGH AND LOW ALARM

When an alarm condition occurs will appear on the display along with a beeping sound to alert user. While the beeping sound lasts
for 60 seconds, the high and low indicators will remain on display even when the unit gets back in range. Press RESET to clear. Press
any key ONCE to stop the beeping sound.

Battery Life

The unit comes with a rechargeable lithium battery. In case of power failure the average battery life is about 20 hours when fully charged.
To achieve longer battery life during operation, use a less frequent sample rate.

TO RECORD DATA

To Use

 Once the Data Logger has been programmed, place the temperature sensor (in glycol bottle) in the location to be monitored, such as

inside a refrigerator or freezer. Data Logger may be placed on top of unit with LCD display easily visible and the alarm audible. Data Logger
displays internal temperature of unit being monitored, as well as maximum and minimum temperatures reached. The Data Logger’s

maximum and minimum readings reflect the highest and lowest temperatures since the battery was inserted or since the RESET button
was last pressed.

 If the temperature measurement rises above or falls below the set temperature range, the alarm will sound. To silence the alarm, press

any key ONCE.

Data Logging / Recording Function

In the Data Logger Setting menu user confirms time, date, and sampling rate.
