Maintenance and change of emergency battery of the recorder
When the green LED of recorder flashes, there are two checking methods:
1. Discharge the emergency battery. If the LED lamp is off and the recorder stops operation, it
indicates that there is problem on the recorder main power (220V/50HZ). Please check whether
there is power outage, short circuit or loose wiring. Install the emergency power when the recorder
operates normally after maintenance of main power. If LED lamp stops flashing, it indicates that the
emergency power is normal. If the LED lamp continues flashing, it indicates that power of
emergency battery is low. Emergency battery needs to be changed until the LED green lamp stops
flashing.
2. Discharge the emergency power. LED lamp of power supply continues flashing and recorder
operates normally, which indicates that the main power is normal and the power of emergency
battery is so low that it needs to be changed until LED green lamp works and stops flashing.
Change Recording Paper
Change of recording paper shall be conducted in the following steps:
1. Find the compress button (3#) on the left corner and in front of recorder panel;
2. Press the button (3#) for about 1 second until the recording pen starts moving to the left side;
3. Loosen the middle bolt when the recording pen moves outside the recording paper. Replace the
old paper with a new one. Align the time line on paper with the time groove on the panel (there is a
small groove on left side of the panel);
4. Tighten the central bolt again. Press the button-3# for about 1 second, to reset the recording pen
and start recording temperature;
5. Examine that whether the recording pen operates well on the paper. If not, beam of the recording
pen can be adjusted to make the nib contact with recording paper. (Note: Do not damage the nib
and beam. If the adjustment is difficult, screw-driver can be used to discharge the beam. Install the
beam after curving the beam through slight force. Repeat the above operations);
6. Accurate recording of the recording pen shall be guaranteed. Calibrate accuracy of the recording
pen after exchange of paper. The method is as follow: Press button (3#) until recording pen leaves
the paper. And press button (3#) again until the pen returns to the paper. At this moment, the pen
will pause at the most external temperature scaling line of the recording paper (this scaling line does
not have to be marked with temperature value, but must be the one at the most external circle). If
the pen does not pause at the above position, you can use 1# or 2# arrow key to adjust the position
within 5 seconds, to align the nib to the scaling line at the most external circle. If position of the pen
is not adjusted well within 5 seconds, please repeat Step 6.
