Power Supply & Pen Information
Pen:
Hysteresis ( a property that occurs when tension is
applied to an object) causes the pens to move in
increments across the chart as the sensor readings
change. However, the display readings are not affected
by the property of hysteresis. For this reason the display
provides smoother and faster readings than the pen. At
any given time there may be a slight discrepancy in the
positions of the pens and the readings on the display.
For visual spot checks the display is the most accurate
but both are within the stated specifications of the unit
(see "Specifications" on page 2).
Pens (2 pen KT6):
The blue pen has a longer pen arm than the red pen. The
pens are offset to allow the red pen to glide under the
blue pen. The blue pen indicates the correct time and the
red pen precedes it by 3/16 of an inch.
Alarm Relays (optional)
The SPST 24V 500mA relay contacts are normally open
and will close on alarm conditions when the alarms are
enabled. Relay contacts are always functional when
the alarm is enabled. Dip Switch #8 has no effect on
the relay. The relay will close only during minimum and

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 is built into the back of
the recorder. NOTE: When the unit is in battery back-up
mode, the recorder will update temperature readings at a
much slower rate. The battery should be replaced once a
year and after power failures of more than a few hours.
To Replace Battery:
1. Open the door of the recorder by depressing the
door latch.
2. Press the "HOME" key
3. Lift the chart, if there is one present, to fully
expose the battery compartment and press down
on the tab to release battery compartment door.
4. Replace 9V battery
maximum alarm conditions. 2 pen units have two sets of
relay contacts which operate independently.
NOTE: For compliance to CE directives, do not remove
the rubber cover from the alarm relay terminals when the
terminals are not used.
