   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.

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.

(Alarm button on KT8P3/KT856 only)

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(s) will move to the outer edge of the chart and 

the shorter red pen will move to the outer chart ring 
(max temperature/RH line). If the red pen tip does not
