KT8P0/2/3:
The R400 Replaceable Sensor was carefully tested and
calibrated before being shipped from the factory.
To order a Calibrated Replaceable Sensor™, call customer
service at (630) 543-3747 or go to DicksonData.com. When
your new Replaceable Sensor arrives, simply turn off the
recorder, remove and discard the old sensor, plug in the
new one and power the recorder back on. Your recorder
will continue to record temperature and humidity without
interruption.
KT856:
The KT856 was carefully tested and calibrated before
being shipped from the factory.
CALIBRATION
If you have an accurate standard to compare against, the
Replaceable Sensor or unit (KT856) calibration can be
adjusted at one point. This will not adjust the span and
is not as accurate as replacing the Replaceable Sensor
with a newly calibrated one, or returning the KT856 for
recalibration.
1. To activate Calibration mode, turn the unit on and press
and hold both the On/Off and the ADJUST-DOWN
button until the LED is solid green. The LED will then
blink amber at which point only the pen being adjusted
will show on the display.
Note: Make sure to press the ADJUST-DOWN button first so
the unit will not turn off
2. To raise the unit of measurement, press the ADJUST-
DOWN button. To lower the unit of measurement, press
the ADJUST-UP button. Pressing PEN HOME switches
between the red and blue pens on a two pen unit and
stores the current adjustment value.
3. When Calibration is complete, press the ON/OFF
button. The adjustment is stored in memory even after
you turn the unit off or if AC power fails.
Note: After two hours, if no buttons are pressed, the unit
will time out of Calibration mode and resume normal
operation. If you wish to cancel the Calibration, simply
enter Calibration mode and toggle through the steps
without adjusting displayed readings. Exit by pressing the
On/Off button. You have now restored factory calibration
settings.
Note: It is recommended that you use a controlled chamber
when determining if Calibration is necessary. Adjusting
the pen locations in an open room is not recommended as
humidity can vary greatly within a very small area.
Note: User calibration invalidates Dickson’s Certificate of
Calibration.
The pen movement for the KT8P0 is slower than on the
AC powered models in order to conserve battery power.
In 24-hour mode the pen(s) will move every 1 minute and
30 seconds. In 7-day mode the pen(s) will move every 8
minutes and 30 seconds. The recorder takes temperature
readings every 50 seconds. An average of the reading
taken between pen(s) movements is what is drawn on the
chart.
USER CALIBRATION
NEED TO KNOW
line up with the outer chart ring, use the ADJUST-UP
and ADJUST-DOWN buttons (on the back of the unit)
to move the red pen so that the pen tip is on top of the
outer chart ring.
3. Once set, press ON/OFF to save and exit PEN HOME
adjust. If using KT856 continue to step 4 below.
4. Once the shorter red pen is set, press PEN HOME to
move the shorter red pen to the outer edge of the chart.
The longer blue pen will move to the outer chart ring.
If the blue pen tip does not line up with the out chart
ring, use the ADJUST-UP and ADJUST-DOWN buttons
to move the blue pen so that the pen tip is on top of the
outer ring.
5. Once the blue pen is set, pressing 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 the
outer chart ring.
6. Each time PEN HOME is pressed, the two pens will
switch positions (moving the most recently adjusted
position) until ON/OFF is pressed to exit pen adjust
mode.
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.
