GETTING STARTED
7-day chart rotation
0 to 100oF
QUICK START
1. Remove the protective pen cap.
2. Connect Probe: Make sure the KTC probe is connected firmly to the Replaceable Sensor and that
the Replaceable Sensor is plugged in firmly to the chart recorder.
3. Insert 4AA batteries and plug in AC adapter (See Figure 3). Unit will power on.
4. The instrument will move pen to the appropriate readings.
5. Install the chart that matches the Dip Switch settings (See p.4).
Press the PEN HOME key to move the pen 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 Clip located at the outside of the chart.
6. 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). Press Pen Home to move
the pen(s) back onto the chart.
The following 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 pen(s) back onto the chart.
c. Place the KT6 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 KT6 recorder for wall
mounting.

button to silence the audible alarm.
Alarm Relays (KT6P5)
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. The relay will close
only during minimum and maximum alarm conditions. Relays will not operate under battery only power
conditions
DIP SWITCH SETUP
To setup the KT6 recorder for your specific application, you might need to change some of the Dip
Switches. The Dip Switches are located on the back of the unit. (Figure 3)
Use a pen or small screw driver to flip the switches. Remember to install the correct chart to match
the corresponding Dip Switch setting.

POWER
The KT6 operates on AC power with an optional 4AA battery backup. Depending on chart
rotation selected and model; battery backup will last approximately 3 days.
Note: Alarm and relays will not operate under battery only power.
LED Indicators
• AC Power with Battery Backup - Solid Green
• AC Power with Low Battery or No Battery - Blinks Red
• Battery Only - Blinks Green
• Battery Only (Low Battery) - Solid Red
PEN HOME ADJUST
If over time the pen location does not match the display, you may need to adjust the pen location
on the chart. A Pen Home Adjustment will not affect calibration of the sensor, but rather corrects
for the natural drift that occurs with mechanical moving parts over time.
1. While the unit is on, press and hold both Pen Home and On/Off buttons until the LED is
solid green. Release the Pen Home and On/Off buttons. The LED will flash amber and
green for one second then the LED will turn off.
Note: Press Pen Home first so the unit will not turn off
2. The pen will move to the outer edge of the chart, and then the red pen will move to the
outer chart ring (maximum temperature line).
3. If the red pen tip does not 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.
4. Once set press On/Off to save and exit Pen Home Adjust.
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.
CALIBRATION
The R400 Replaceable Sensor was carefully tested and calibrated before being shipped
from the factory. For greatest accuracy, we recommend replacing the sensor every 6-12
months.

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.
USER CALIBRATION
If you have an accurate standard to compare against, the Replaceable Sensor 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.
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 and 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.
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 in an open room is not recommended as air flow can vary
greatly within a very small area.
TROUBLE SHOOTING
Why isn't the chart keeping time or running slow?
The chart may be hung up or restricted, possibly caused by a rip on the outer edge of the
chart or the chart hub, or the chart may be caught between the arm and pen(s) arm
platform.
Incorrect chart installed for the selected chart speed.
Why did the chart stop turning?
Chart hung up or restricted, (ripped chart)
Unit may be "locked up", this can be confirmed by pressing any of the buttons on the
keypad, if the unit is locked up there will be no response to button presses and the Chart
Recorder may appear to be working, but the readings won't change, also the chart will
not rotate. Remove power and battery, and then re-power.
Why don't the display and chart match?
Dip switches set for a specific range, but using chart for another range, or vice versa.
Pen(s) not inserted on pen arm(s) all the way
To adjust pen(s) to match chart see “Pen Home Adjust” in the “Need to Know” section of
this manual.

Why does the display read PROB?
Check the sensor pod and KTC probe(s). Make sure it is properly plugged into the unit.
Is the unit locked up? This can be confirmed by pressing any of the buttons on the
keypad, if the unit is locked up there will be no response to button presses and the unit
may appear to be working, but the readings won't change, also the chart will not rotate.
Remove power and battery, and then re-power.
Why does calibration seem to be off?
What is the tolerance of the unit it's being compared to?
It's ok if the unit is within the sum of the two tolerances.
Has an outside calibration house attempted calibration? It may not have been adjusted
properly.
Walk through calibration adjustment, found in the manual
Why won't the battery back-up work?
Are there good batteries in the Chart Recorder?
Keep in mind that battery backup varies significantly depending on temperature, pen
movement and chart rotation speed.
If there was a momentary power outage (Brown out), the unit may not have had enough
time to recognize this and switch to battery mode. (The Chart Recorder may lock up or
shut off in this situation) This situation may also occur if the unit is plugged into an outlet
that shares the circuit with other machinery that has phase motors or compressors that
cycle periodically. As these other machines cycle, they momentarily have a high current
draw, therefore drawing from the unit.
Why won't the chart recorder respond to changes?
Is the unit locked up? This can be confirmed by pressing any of the buttons on the
keypad, if the unit is locked up there will be no response to button presses and the unit
may appear to be working, but the readings won't change, also the chart will not rotate.
Remove power and batteries, and then re-power.
Why won't the unit power up?
Remove the batteries and power adapter for a minute or two, this will reset the unit. The
unit should respond when the adapter is plugged in.

Replaceable Sensor Certificate of Validation
Dickson ensures that the Replaceable Sensors / Instruments listed below were developed, tested
and validated together.
Replaceable Sensor Model: R400
Instrument Model: KT6P1, KT6P2, KT6P5
Operation: The Instruments and Replaceable Sensor models listed above were specifically
designed to work together. No other sensors will work with the Instrument models listed. No
other Instrument will work with the Replaceable Sensors listed. The Replaceable Sensor must be
connected to the Instrument for the Instrument to operate properly.
Calibration: Only the Replaceable Sensor is calibrated. The sensor, and all calibration defaults
and adjustments are stored on the Replaceable Sensor. Accuracy is strictly controlled by the
sensor –no adjustments are made by the Instrument. Readings are sent from the Replaceable
Sensor to the Instrument for storage purposes only. Certificates of Calibration / NISTs are only
supplied for the Replaceable Sensor for this reason.
Recalibration: When a Replaceable Sensor is due for recalibration the existing Replaceable Sensor
can be replaced with a new Replaceable Sensor thus eliminating the need to return the entire
instrument for recalibration. Replaceable Sensors can be returned for recalibration as well.
