Replacement of the Pen:
Recorders that are equipped with fiber tipped cartridge pens will have a cartridge that is
color coded "red" to designate pen number one and an optional cartridge that is color
coded "blue" to designate pen number two. The pen cartridge is securely fastened
to the metal pen arm using a special "U" clip tab. For ease of replacement, it is
suggested that the two screws that hold the pen arm be loosened and the pen cartridge
and metal pen arm be removed as an assembly. Unsnap the plastic "U" clip tab of the
pen cartridge from the metal pen arm, remove and discard the old pen cartridge.
Replace the new cartridge by opening the hinge and snapping it securely around the
metal pen arm. Refer to the image below:
Pen Arm Calibration:
To check and/or adjust the recording pen(s) calibration to the outer most temperature
graduation of the chart, press and hold the "change chart" button (#3) until the pen
begins to move off of the chart. Once the pen(s) has moved off of the chart, again press
and hold the "change chart" button (#3) until the pen begins to move back onto the
chart. The pen should briefly stop at the outer most temperature graduation of the chart
before continuing onto the chart to begin recording. If the pen does not stop exactly at
this location on the chart, it can be adjusted or "calibrated" by using the left (#1) or right
(#2) arrow buttons.
When the pen moves back onto the chart and briefly stops, you will have approximately
five seconds in which to adjust the pen’s position using the left and right arrow buttons of
Figure 3.
On multiple pen recorders, each pen will move (one at-a-time) onto the chart briefly
stopping at the outer most temperature graduation of the chart at which time the pen’s
position can be adjusted by using the left (#1) or right (#2) arrow buttons. When the time
to adjust the position of the first pen has expired, the second pen will move onto the
chart briefly stopping at the outer most temperature graduation of the chart at which time
the second pen’s position may be adjusted.
