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

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.

10 Introduction

Connections

voltage conductivity pressure pH

and temperature

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.

The input bushes are intended exclusively for pH-electrodes. Other signals

may destroy the device.
