CHART RECORDER INSTALLATION
Please note that the following information is a general guide for installation.
Chart recorders are available from your dealer. Before attempting installation
please read the instructions provided with your chart recorder thoroughly for
specific installation instructions. Note: Unplug unit from the power supply before
installing the Chart Recorder.
6.1 Remove cover for Chart Recorder, located on the right side of control panel.
6.2 Remove steel plate from the back of the Chart Recorder.
6.3 Open the front glass door on the Chart Recorder and loosen the two screws on
the face of the recorder. (Screws are on the top and bottom right of the face.)
6.4 Inside the unit, behind the cover plate, you will see two wires that say “Recorder
Power”. Cut off the butt connectors and strip the wires about 3/8 inch.
6.5 Put the Recorder Power wires through the hole in back of your Chart Recorder
and connect the Recorder power wires to the terminal inside.
6.6 Run the Chart Recorder probe through the probe hole and slide into probe clips
provided inside the chamber of the unit.
6.7 Inside the Chart Recorder you will see a piece of masking tape and a metal clip;
remove these; screw face bolts back in; screw in Chart Recorder; shut the glass
door on the Chart Recorder; plug unit into power supply; then turn on the unit.
6.8 In moving or mounting a chart, the pen arm and stylus must be raised by
pressing on the tab at the uppermost end of the arm. Even if the recorder is not
to be used, a fresh chart should be mounted or some sort of padding placed
under the stylus to protect the sapphire tip.
6.9 To remove and replace a chart, unscrew the hub knob and swing it 90

clo ckwise, or to the 3 o’clock position. Press the upper tab on the pen arm; lift
the chart forward off the hub and slide down and away. DO NOT release the pen
arm, but install a new chart.
6.10 Now the pen arm may be gently released and the chart knob rotated
counterclockwise back to the hub. Align the proper chart time with the chart plate
index.
