Change Chart button when you have finished configuring the last category in order to
save all of the changes that have been made to the recorder's configuration. The
thermal pen arm will move off of the chart allowing you to place the recording chart
paper onto the recorder. Press and release the Change Chart button to begin
recording.
Changing the Chart Paper:
Press and hold the Change Chart button (#3) for approximately one (1) second until
the pen begins to move off scale and then release the button.
Note: The green LED light will flash fast while the thermal pen arm is moving off scale.
Wait until the thermal pen arm has moved completely off scale and stops (the green
LED light will stop flashing and will be steady On). To remove the chart paper, unscrew
(counter clockwise) the chart "hub" knob at the center of the chart. Gently lift the
thermal pen arm just enough to be able to slide the paper out from beneath it. Remove
the old recording chart paper and position a new one.
Re-attach the chart "hub" knob and screw securely (by hand) against the chart. Press
and hold the Change Chart button (#3) again for approximately one (1) second and the
thermal pen arm will move back onto the chart and begin recording.
Green Light LED Status:
The green LED light (located just below the three button membrane switch) is used to
show the recorder's status:
1.) LED on steady (not flashing) and input(s) recording within chart range, indicates
unit is recording normally.
2.) LED on steady (not flashing) and pen arm above outermost graduation and not
moving, indicates recorder is in Change Chart mode. Press and release Change Chart
button to return to normal recording mode.
3.) LED flashing rapidly and one or both inputs recording at outermost or innermost
graduation indicates a sensor break. Check or replace sensor(s). If sensor(s) are ok,
make sure process temperature is within configured range of recorder.
4.) LED flashing slowly (.8 seconds ON / .8 seconds OFF) indicates recorder is in
Set-Up mode. Refer to section CONFIGURING THE RECORDER.
