Changing the Rotation Time of the Chart

The chart rotation time is set at the factory before your Guardian is shipped. Rotation refers to
the amount of time it takes the chart to complete one full rotation. For example, if the rotation
time is set for 48 hours, it will take 48 hours for the chart to complete one full rotation.
To change the chart rotation time (i.e., from 48 hours to 7 days), follow this simple 11 step procedure:
1. Open the door to the Guardian recorder. On the front of the platen in the lower left hand corner is a
small cover held in place by a screw. Remove the screw and the cover to reveal the MODE switch.
Move the switch from the RUN position to PROG/CAL/TEST.
2. The display will read "Prog." Press the DOWN arrow button.
3. The display will read "Pen-1." Press the SCROLL button.
4. The display will read "Pen-2." Press the SCROLL button.
5. The display reads "Chrt." Press the DOWN arrow button.
6. The display will read "ChSP." Press the SCROLL button.
7. The existing rotation time period will be displayed (i.e., 48 hours). Press the UP or DOWN arrow
keys to step through the rotation time periods (24 hr., 48 hr., 72 hr., 7 day). Stop at your desired
rotation time.

10. Move the switch from the PROG/CAL/TEST position to the RUN position. Replace the small
cover over the MODE switch and secure with the screw provided.

to the new chart speed that was just programmed. For example, if chart speed is programmed for 7
days, choose a 7-day chart. Close the door of the Guardian.
