Note:
The stylus does not begin to move until the button is held for five
seconds.
If you find that the recorder frequently needs to be calibrated after paper
changes, the program may have changed. To confirm that the program is
correct:
1. Press button #3 in Figure 6 and allow the pin to move off the scale.
2. Press #1 for 10 seconds and release.
3. Confirm that the green LED flashes 3 times followed by a pause. If the
number of blinks is greater than or less than 3, adjust the number using
the left (#1 in Figure 6) and right (#2) chart buttons.
4. When the green LED blinks 3 times to confirm the resetting, press the
#3 button. The pin arm should then return to indicate the current
temperature. Repeat Steps 1-3 if necessary.
