If KT856 two pen model, the additional options are:
»
Pen 2 ALARM minimum
»
Pen 2 ALARM maximum
3. In order to set pen(s) ALARM minimums and maximums,
pressing ADJUST-UP will increase the ALARM value,
and pressing ADJUST-DOWN will decrease the ALARM
value. There is acceleration if the ADJUST-UP button is
held down.
Repetitively pressing the PEN HOME button will scroll
through the five options until the ALARM button is
pressed to exit from ALARM adjust. Each press of the
PEN HOME or ALARM button will store the new settings.
The unit will take one minute to exit ALARM Set Mode
once the ALARM button is pressed.
4. If the ALARM is triggered, the LED will show as solid red
and the ALARM will sound. Press the ALARM button to
silence the audible ALARM.
ALARM RELAYS
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. The KT856
has 2 sets of relay contacts which operate independently.
Relays will not operate under battery only power
conditions.
The blue pen has a longer pen arm and records channel
2 temperature (depending on your dip switch selection).
The red pen has a shorter arm and records channel 1
temperature. 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.
7-DAY CHART ROTATION
0 TO 100°F
IMPORTANT
Dickson Chart Recorder accuracy specifications are only valid with the use of authentic
Dickson brand charts and pens. The specifications for chart printing, die cutting and paper
absorption rates, and the complementary bleed rate specifications of pens are critical factors
in determining system accuracy.
TO BEGIN OPERATION
1. Remove the protective pen cap(s).
2. Connect probe(s).
a. KT8P0/2/3: 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.
b. KT856: 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 batteries and plug in AC adapter (See Figure 3).
a. KT8P0:4 AA batteries required
b. KT8P2/3 & KT856: 4 AA batteries backup power only
.
Unit will power on.
4. The instrument will move pen(s) to the appropriate
readings.
5. Install the chart that matches the DIP SWITCH settings.
6. Press the PEN HOME key to move the pen(s) to the
outside of the chart. The pen(s) is automatically raised
off the chart.
7. 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.
8. 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.
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.
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 KT8 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 KT8 recorder for wall mounting.

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
