3.
One pen model: The red pen will move to the outer edge of the chart and is ready to be adjusted. Use
the Adjust-Up and Adjust-Down buttons to move the pen to the maximum temperature line on the chart.
Once the pen is set, the Pen Home button will move the pen to reaffirm the new pen position. Press the
On/Off button to exit pen home adjust.
4.
Two pen models: Both pens will move to the outer edge of the chart, and then the shorter red pen will
move to the current position. Use the Adjust-Up and Adjust-Down buttons to move the pen to the
maximum temperature line on the chart. Once the shorter red pen is set, the Pen Home button will move
the shorter red pen to the outer edge of the chart and the longer blue pen will move to its current
position. The Adjust-Up and Adjust-Down buttons will adjust the longer blue pen position. Once the
pen is set, the Pen Home button will move the longer blue pen to the outer edge of the chart and the
shorter red pen will move to its new position. Each time pen home is pressed the two pens will switch
positions (moving the most recently adjusted position) until the On/Off button is pressed to exit pen
adjust mode.
5.
Note: Pressing the On/Off button will exit the adjustment and return the unit to normal operation. Each
time the pen home or On/Off button is pressed, the adjustment currently in progress will be stored. The
unit will take one minute to exit Pen Adjust Mode once the On/Off button is pressed.

Probe
A beadwire K-thermocouple probe is supplied with your unit. This probe may be used as a disposable
attachment and re-ordered when needed.
Power Supply
We recommend using AC power with one 9V battery installed as a back-up power source. This ensures that
your recording will not be interrupted when there is a power failure. The AC adapter plugs into the back of
the recorder beneath the probe. This is not a battery powered unit. The battery is for backup only. If there is
not a backup battery in the unit, the LED light will remain red. This unit includes an AC adapter.
Pens
The pens move across the chart as sensor readings change. At any given time there may be a slight
discrepancy in the position of the pen and the reading on the display due to hysteresis.
For visual spot checks the display is more accurate than the pen position but both are within the stated
specifications of the unit (see "Specifications" on pg. 2).
