non-condensing (relative humidity)

 Accuracy : ± 0.5 oC (-10 ~ 10 oC or 14 ~ 50 oF), in other range ± 1 oC ( or ± 2 oF)
 User defined logging interval
 6.5 ft (2 meters) NTC probe-connecting cable
 Rechargeable Li-ion battery to record data up to 8 hours during a power-failure

NOTE: Before use, remove and discard the clear plastic protective film from the screen (LCD).

 Place the temperature sensor (in glycol bottle) in the location to be monitored, such as inside a refrigerator or

freezer. The 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 unit

was powered or since the MIN/MAX history was cleared.

 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.

 Clear MIN/MAX history once the unit is stable.
