Attention
Read these safety instructions before using the HDM99
•Please read the manual before using the HDM99.
•Keep away the device from unauthorized persons.
•Never use the HDM99 with connected battery charger
on a dialysis machine to which a patient is connected.
•Operate the instrument only in a dry environment, and
do not touch it with damp hands. Ensure that no fluids
intrude into the interior of the device or into the sockets
at the front.
•Apply a protection filter to the nozzle for the pressure
measurement .
•Avoid a discharge of static electricity over the sockets.
It could lead to the destruction of your measuring
device. Before touching the sockets and lines that are
connected with them, keep an eye on the discharging of
static electricity.
•Voltages above 40V can be dangerous. Take extreme
care while working with higher voltages.
•To avoid electrical shocks, and/or damage to your
measuring system, do not apply excess voltages above
40 V to the instrument.
•Only calibrate the device if you have understood the
consequences to their full extent.
•Do not open the device.

Guarantee directives
The existing product is a technical device which contains only modern
electronic components. During the manufacturing exclusively first choice
parts are used. Each device undergoes extensive tests before delivery.
IBP warrants that the device is free from defects in material and
workmanship for a period of 12 months beginning at the date of delivery.
Excluded from the guarantee are damages by improper treatment,
inappropriate usage, by connecting to excess voltages, modifications in the
device or through risks which the user has to cover by a suitable insurance
(fire, water, intrusion, robbery etc.)
All conceivable measures were met to assure the accuracy of this product-
documentation. IBP cannot grant any guarantee for the completeness and
the accuracy of the software and the documentation. IBP is not responsible
for damages (including, but not limited to, damages for loss of business
profits, business interruption, loss of data, and other special, incidental or
consequential damages) which emerge through the usage of the product by
the customer.

Introduction 9
Introduction
HDM99 is an innovative computer processed measuring system with which
nine parameters can be measured:
Conductivity
Temperature
Pressure
pH
Flow
Voltage
Frequency
Period time
Events
The device has been developed for the usage on dialysis machines, but is
also usable in the labor in the environmental measuring technology.
The handling is uncomplicated and follows the motto: Only the manual is
necessary in cases of doubt.
The entire handling is led by dialogues. The calibration of the device by the
user is simple and gives no problems.
The display of measurement results is available n numerical and also in
graphical form.
Via the serial interface the measurements can be called independently of
the current display, and further processed or presented on a PC. For the
fault location at dialysis machines IBP has developed a program that
presents and processes measurements of the HDM99 and of the machine
together. Provided that the dialysis machine is equipped with an interface
according to RS232-or RS485-standard. Drivers for different instruments
are available or in preparation. The program runs under MS-Windows and
is therefore easy to operate.

Voltage
The sockets are intended only for AC and DC voltages up to 40 V. They
are protected up to 80 V.
Conductivity / Temperature
The conductivity measurement is designed for quadropole technology.
Please use exclusively the electrode delivered with the device by IBP.
Pressure
To avoid damages at the pressure probe or inaccuracies in measurement,
ensure that no fluids intrude into the device.
We recommend the application of a protection filter.
pH
The input bushes are intended exclusively for pH-electrodes. Other signals
may destroy the device.
