TEMPERATURE RECORDER (OPTION)
Starting recording and setting the time:
Turn the power switch ON. The pen will move inward on
the circular recording chart and stop temporarily at the 0%
position (equivalent to the 40
o
C line). Then the pen will
move to the position which indicates the measured
temperature.
Time setting Method:
Place the recording chart at a position slightly in front of the
desired time (the chart is rotated to the left). Set the time
by using the fast feed button to quickly rotate the chart.
The fast feed button can be used to accurately set the time.
NOTE:
There is a difference of approximately 2 mm between the red pen and blue pen during recording.
The time difference between the red pen and blue pen changes according to their position on the scale.
It is roughly two hours for 0% position of chart center and roughly one hour for 100% position (when the
recording chart speed is set to seven days).
When the recording chart speed is set to 32 days:
The center of the recording chart is divided into 32 equal
sections. The lines extending from these lines serve as the
32-day time scale.
Stopping recording:
1.
Turn OFF the power switch.
2.
When recording is stopped for a prescribed period, place
the caps back on the pen cartridges to prevent the ink from
evaporating.
Replacing the recording chart:
1.
Slightly raise the end of the pen lifter and remove from the pen lifter stopper. Rotate the tip of the pen
clockwise until it rests on top of the pen lifter.
2.
Remove the chart hub cover, and then replace the recording chart.
3.
Place the chart hub cover. Remove and dispose of the piece of paper. Confirm that the new recording
chart is inside of the chart guides.
4.
Set the correct time.
