Product Overview

Measuring Channels

Flow/Alternating
Signal Connector

Pressure Inlet

Voltage Connector

pH-Connector

Conductivity/Temperature Connector

Only use accessories provided with the HDM99XP. Use of other devices may damage the instrument and
will void the warranty.

Conductivity/Temperature Sensor

The Conductivity/Temperature probe is a quadropole design for greater accuracy and longevity than other
designs. Take care to properly align the pins in the connector when attaching the transducer.

Pressure

To avoid damage or inaccurate measurement, ensure that no fluids enter the instrument. We recommend the
use of a Transducer Protector for this purpose.

pH

The input connector is designed exclusively for pH electrodes. It is optimized for glass electrode single-rod
measuring cells with a slope of

∆E of 59mV at 20°C. Its absolute maximum allowable input voltage span

extends from -3 Volts to +3 Volts with respect to BNC Shield. Applying any voltage beyond these
boundaries will possibly destroy the instrument.

Precautions using the pH Probe input

Due to the high sensitivity of the pH input it can not be fully protected against
electrostatic discharge. It can only be protected by plugging the protective cap to its
BNC receptacle. Always attach the protective cap, if the pH input is not used. Do
not leave the input open, otherwise the circuit inside may be damaged. The
minimum input impedance of the input is 10 Tera Ohms (10*10
leakage current is typ. 2 femto Amperes (2*10

-15)

Amperes.

12

Ohms). The

Flow

The input voltage range is +5...+24 V.

Frequency, Periodicity and Events

The input voltage range is +5...+24 V. The form of the signal should be of a rectangular form and has to be

positive.

7 Introduction

Voltage

The sockets are intended only for AC and DC voltages up to ± 40 V. They are protected up
to ± 80 V.

Battery Charger

The HDM99XP is equipped with an internal NiMH battery for extended run times when not connected to the
external charger. The charger provides a 12 V/1500 mA charge to the battery. A message appears on the
display when the battery requires charging.
The charging process could be controlled with the green and red LED on the right side of the meter. The
green LED indicates that the power supply is connected. The red LED indicates fast charging if continuously
switched on and low level charging if blinking. The complete charging cycle takes about 3 hours with empty
batteries.

For maintenance details, consult the maintenance section of this User Guide.

To avoid hazardous voltages in case of a defective battery charger never use

the HDM99XP on a dialysis machine with a connected battery charger.

For security reasons no measurement during battery charging is possible. In this mode you will receive a
display showing the state of the charge. For special applications a special battery charger with extremely low
leakage current (LLC-Charger) is available, which allows measuring during the charge of the battery. The
HDM99XP automatically detects the type of battery charger connected.

Flow Through Adapter

Nut for opening

Í

Dialysate
pressure
outlet

The Conductivity/Temperature Transducer may be used in two ways.

In the Flow-Through Mode (illustrated at left) the user may measure pressure,

temperature and conductivity with the included Flow Through Adapter. The
preferred position of the Hansen connector is vertical, the axial supply is show at
the bottom of the illustration. In the Flow-Through Mode the axial supply is used as
input and the radial supply as output. The pressure probe in the HDM99XP is
fastened to the radial connection above the input. Before any measurements you
must shake the connector to assure that any air within the system escapes.

In the Dip Mode temperature and conductivity can be measured. For this mode

open the screw cap as show in the picture of the connector and extract the
combined electrode. You must not remove the tube covering the probe carrier. Dip
the electrode into the media up to a level above the holes in the covering tube. By
moving the electrode you assure that the trapped air can escape and the temperature
is well balanced.

Never touch the electrode surfaces with your fingers or other
objects.

Do not buckle the cable of the probe.

The minimum allowed bending radius is m e.g. 3 cm (1¼ inches).

The switch-off time is the time after the last key activation. At the end of this time the device switches off

automatically.

The activation of the function switch-off leads to a selection of times which can be selected with the arrow­keys. The chosen time is shown inverted and taken over with ok as new switch-off time in the installation

menu. If >--< is chosen, the automatic power shutoff is cleared, the device remains active until it is switched

off manually with the key >OFF<.

11 Introduction

Adjust-reset

With the adjust-reset the calibration values for all measuring channels can be set to basic values. These basic
values are the calibration values of the company conducted calibration. Operate the function key beside this

menu point. You will have to enter a code via the numeric keyboard. This code is 1704. When you confirm

your input with >enter< you will receive the following images:

With the function keys beside the individual measuring channels you can decide on which calibration values
this function should be applied. The calibration values will be reset to basic values.

If for individual parameters the function adjust reset was used, then a new verification is necessary for these

parameter.

The reset of the flow measurement only resets the parameters of the flow sensors 1....7. The possibly existing

calibration values of own sensors remain unchanged.
