Quick Start

1. Remove the protective pen caps.
2. Insert batteries and plug in AC adapter.
(See Figure 3.) (TH8 requires 4 AA batteries only.)
The unit will power on.
3. The instrument will move pen(s) to the appropriate
readings.
4. Install the chart that matches the Dip Switch settings
Press the Pen Home key to move the pens to the
outside of the chart. The pen is automatically raised
off the chart.
Remove the old chart, place the new chart on the
Chart Hub being certain that the edge of the chart
slides under the Chart Guide Clips located at the
outside of the chart.
5. Set the appropriate time. There are two ways to
adjust the chart and set the appropriate time:
a. Set the chart time manually by inserting a coin into
the groove in the chart hub and turning clockwise
until the correct hour (and day if applicable) on the
chart is referenced to the timing arrow (just to the
right of the pen tip on the dial).
This feature should be used for fine adjustments only.

b. To adjust the chart time, press and hold
Adjust-Up and Adjust-Down buttons located
on the back of the unit next to the dip switch (see
Figure 3).
The green LED will blink rapidly for about five
seconds, then the LED will remain solid green.
While in this state the Adjust-Up button will move
the chart backward (counter clockwise) and the
Adjust-Down button will move the chart forward
(clockwise).
Rotate the chart until the correct hour (and day if
applicable) on the chart is referenced to the timing
arrow. Once you have set your chart, press the Pen
Home button to exit Chart Adjust Mode. The unit
will take one minute to exit the Chart Adjust Mode
once Pen Home is pressed.
Press Pen Home to move the pens back onto
the chart.
6. Place the TH8 recorder on a flat vibration-free
surface. Be sure it is in a vertical position and level.
For best performance and longevity, the location
should be a clean environment, free from dust
and corrosive fumes. Do not exceed temperature
specifications.
Wall Mount Keyhole slots are provided on the TH8
recorder for wall mounting.
