2.Power supply
The temperature recorder requires an AC power supply. If AC power supply is
interrupted, the LED of the recorder blinks and the warning indicator turns on. The
temperature recorder can also be operated with DC from spare source battery which
lasts about 30 hours.(Caution: The battery should remain fully charged. If the unit is not
in operation, the battery should be switched off. Ensure that the battery is in good
status as a spare power source.) If power fails, the LED of the temperature recorder
blinks until AC power is supplied or spare power source is connected. The LED
indicator will blink when the power in the battery is low.
Replacement of Recorder Battery
When the green LED on the recorder flashes, there are two ways to inspect the unit.
1) Supplementary power supply (9 volt DC)
If the LED light is off and the recorder stops working, it would suggest that there might
be issues associated with the main power supply. Please inspect whether there is a
loss of power, a short circuit, or a loose connection. If there is no issue with the main
power supply and the recorder starts working normally, please install the backup
battery to the recorder.

At this time, if the LED stops flashing, the supplementary
power supply is normal. If the LED continues to flashes, it means that the power supply
is under capacity requirement. It is necessary to replace the battery. The LED green
light is off when there is sufficient power to the recorder.
