Each time the chart paper or fiber tip pen cartridge is changed, you should make sure
that each pen stops at the outer most temperature graduation of the chart paper.
Otherwise, this pen offset will cause the unit to record an incorrect temperature on the
chart.
Recorder Calibration:
If a calibration adjustment is required for a single pen recorder, use the left (#1) and right
(#2) arrow push buttons on the recorder to calibrate (or move) the pen’s position on the
chart to correspond to the temperature of the solution. The arrow buttons must be held
for approximately five seconds before the pen will begin to move.
For two pen recorders, you must first select the pen that you wish to calibrate. This is
done by pressing the left (#1) arrow button to select the red pen or the right (#2) arrow
button to select the blue pen. The arrow button must be held down until the green LED
light goes out. After the green LED light goes out, follow the instructions in step #3
above.
Battery Backup:
The green LED light remains a constant green color indicating that both the battery and
the main power to the unit are good. Refer to Figure 5 for the location of the green LED
indicating light. If the AC power were to fail or the battery becomes weak, then the green
LED light will begin "flashing" indicating that either you have lost the main power to the
unit or it is time to replace the battery. Having a 9 volt DC battery back-up in place, will
allow the recorder to continue to function normally for approximately 24 hours in the
event of a power failure.
