IMPORTANT
Dickson Chart Recorder accuracy specifications are only valid with the use of authentic Dickson brand
charts and pens. The specifications for chart printing, die cutting and paper absorption rates, and the
complementary bleed rate specifications of pens are critical factors in determining system accuracy.
TO BEGIN OPERATION
This recorder comes with 1 AA battery installed.
1. Set chart rotation: the switch is located in the battery compartment. Unscrew the battery door. Make
sure the switch is set to the correct chart rotation speed.
2. Replace the chart paper
3. Set time by inserting a coin into the chart hub and turning it clockwise until the current hour is
referenced to the time indicator (time indicator is directly to the right and below the pen tip.
4. Remove protective pen cap
BATTERY REPLACEMENT
• The battery compartment is located on the back of the unit
• The recorder uses a standard AA battery for up to two years of battery life
• Insert new battery with positive end up
CHART NOT ROTATING
• Make sure the chart paper is not ripped in the center around the Chart Hub
• Make sure the chart is not hung up or restricted
• Make sure there is a good battery being used and it is installed correctly
PEN DOES NOT MATCH DISPLAY
• The chart recorder and digital display are two independent measuring instruments, with dierent
specifications. There is a certain amount of discrepancy allowed between chart and display, depending
on the range of the chart recorder. An SL4100, for example, has a scale of 0 to +100 degrees (a range of
100 degrees). That means a 2 degree tolerance for the chart. The digital display has a tolerance of 3.6
degrees, which means there is a maximum allowed discrepancy of 5.6 degrees between the chart and
display. The chart may be adjusted using the pen adjust screw on the face of the unit. If the display is
out of specification, the display can be replaced but not calibrated.
