Operation Instructions
Temperature Recorders
The appliance is equipped with a six inch recorder, which starts operation after the appliance is
connected to power supply.
1. Installation and Operation
Following are procedures for correct operation of the temperature recorder.
1. Open the door of the temperature recorder cabinet.
2. Connect the temperature recorder to the battery (9V) as spare power source.
3. Load new pressure-sensitive chart paper.
4. Remove the plastic cap of the ink market pens, and close the cabinet door.
Caution:
The recorder does not until the temperature in the appliance reaches the value within the
operation range of recording.
2. Power Supply
The temperature recorder requires an AC power supply (220V/50Hz). 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 appliance 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.
Maintenance and replacement of temperature recorder
Following are inspection procedures when the green LED blinks.
1. If LED extinguishes and the recorder does not operate, check to see if AC power supply is
interrupted, the circuit shorted or cables are not connected. After AC power supply is recovered,
install the battery. If the battery is in good condition, the green LED indicator turns on but does not
blink. Low voltage of the battery may result in the LED flashing. Replace the battery.
2. If the battery is removed, the power indicator LED blinks. The temperature recorder operates with
AC power supply. The green LED indicator blinks until a good battery is reinstalled.
