1. Your K 100
is an instrument of Dr. A. Kuntze GmbH which offers you high quality and reliability for
years.
It is a member of our economy series K 100 with which we are trying to meet the rising
demand for lost cost / high end instrumentation.
The instruments K 100 are defined by an excellent pricing. They were developped to
maximize functionability for standard applications.
Operation requirements are reduced to an absolute minimum: For standard
electrodes no adjustments are required. The caibration solutions are automatically
recognised, regardless of the order in which they are used. After every single
calibration step the calibration curve is recalculated, so you can work with a 1-point
calibration, if you like.
For any non-standard application you can alter all parameters connected with
calibration: for restricted or outlying measuring ranges you can adjust the calibration
solutions as well as the zero-point of your measurement which is defined by the inner
buffer of the electrode.
All instruments K 100 have an integrated controller which provides bidirectional PI
control, via two relays or as a steady-state controller via the analog output. You can
define a turn-on delay to prevent wrong dosage after power failure and operate the
controller by remote control. Connect a level sensor, and the controller will shut down
automatically in case of lack of water.
Not to mention the alarm function with minimum and maximum limit and turn-on
delay...
You have certainly made a good choice. On the following pages you learn more about
your K 100. If, however, you have further questions or are looking for information not
included in this manual or if you are interested in supplementing products like
sensors or armatures or in our other instrument series, just give us a call - we will be
delighted to help you!

2. Instructions for installation and
connections
Installation:
On the next pages you will find detailed instructions for the installation.
For panel-type meters you have to prepare an opening of 92x92mm. Install the
instrument and fix it with the two mounting clips which were part of the delivery.
You can install instruments in wall-mounting enclosures either by hanging them upon
the center slot or by sliding the slot under a screw, which is an alternative for limited
space. Either way you have to fix it additionally with two screws.
ATTENTION Install the instrument in a place where it is not put under mechanical
or chemical strain!
Mind the protection class:
K 100: Front IP54, with front door IP55
K 100 W: IP65 (closed terminal cover)
Connections:
You will find detailed connection diagrams on the following pages.
Before connecting the power supply check the information on the instrument label!
ATTENTION Input, output and control lines must be installed separate from each
other and separate from power lines!
For inputs and outputs use screened lines and connect the screen on one side only.
The pH measurement is interference-sensitive. Use a special screened cable and
over long distances or in humid atmosphere additionally an impedance converter.
For the connection of the temperature sensor Pt100 use a low-resistance cable with a
large diameter.
When using the relays, mind that with inductive loads, interference must be
suppressed. If that is not possible, the relay must be protected at the terminal block in
the K 100 by a resistance-capacitance filter or, in case of direct current, by a free-
wheeling diode.
