The options at a glance
Your device might be equipped with one of the following options.
Option H
Option H is a higher accuracy in pressure measurement.
Please note that the sensor is not fluid resistant with this option.
Option identification is an Hbehind the product name, for example HDM97BQH.
Option C
Option C is a connector for the conductivity probe.
Please note that the probe is calibrated with the meter and cannot be used with other meters.
To use the probe with other meters a new adjustment of the temperature and conductivity is needed. After
these adjustments the meter will accept the probe in the future.
Option identification is a Cbehind the product name, for example HDM97BQC or HDM97BQHC.

9General
Measuring Channels
Only use accessories provided with the HDM97Pocket . Use of other devices may damage the instrument and
will void the warranty.
Conductivity/Temperature Probe
The conductivity/temperature transducer is a quadropole design for greater accuracy and longevity than other
designs.
Standard precision pressure transducer
This pressure transducer is watertight. However it is recommended to keep fluids away from the sensor
because residues like salt can falsify measurement results. In this case the sensor needs to be flushed with
deionized water.
High precision pressure transducer
To avoid damage or inaccurate measurement, ensure that no fluids enter the instrument. We recommend the
use of a Transducer Protector for this purpose. Never flush the sensor.
Pressure drop measurement
This is not a real channel, it is a function for measuring pressure loss in systems for a specified time.
Timer
This is not a real channel, it is a function to help performing anything where time is a crucial element.
pH
The input connector is designed exclusively for pH electrodes. It is optimized for glass electrode single-rod
measuring cells with a slope of ΔEof 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.
Flow
This connection is designed to be used with the HDU FLOW97 probe only. Do not connect any other
devices to this port even when the connector may fit.

General
10
Charging the battery
The HDM97Pocket is internally equipped with a high performance Lithium-Ion-Polymer battery. It can be
charged using the external power supply, a PC or a laptop which is connected via the USB cable to the
instrument. The battery of the HDM97Pocket can only be charged from USB ports which are capable of
delivering 500 mA of current.
This is appropriate to most connectors of laptops or PC's. Connecting the meter to a
passive (e.g. not externally powered) USB hub, the battery can not be charged and
the communication may not work well. During the charging process the battery
symbol in the display is animated.
Performing measurements while the battery is being charged
The HDM97Pocket can be used for measuring while the battery is being charged.
ATTENTION: The USB connector is not part of the appliance part.
Flow-through adapter for conductivity and temperature measurement
The adapter is suitable for measuring pressure, temperature and conductivity
in flow-though mode. With immersion usage of the probe it is suitable for
measuring temperature and conductivity concurrently. The preferred
orientation of the adapter is vertical. The axial connector must point down
(see picture). In flow-through mode the axial connector is to be used as inlet
meanwhile the side connector is to be used as outlet. The connection to the
pressure transducer inside the HDM97Pocket is accomplished by the lateral
connection above the inlet. Before measurement it is necessary to shake the
adapter slightly, so that air bubbles trapped inside can pass off through the
outlet.
For immersion usage the probe must be unscrewed from the flow-through
adapter. To accomplish that do not turn the upper shank, the probe may be
damaged. Only turn the nut as shown in the picture left.
Never touch the carbon ring electrode surfaces with
your fingers or other objects.
Do not buckle the probe cable. The minimum allowed
bending radius is 3 cm or 1¼ inches.

Display test during start up
Immediately after switching on the instrument the display shows all
possible segments dark for two seconds. Compare the display with
the picture on the right side. Do not use the instrument further if you
discover any missing segment, because wrong values could be
displayed which may lead to misreading.
The content of the display must be shown exactly like this picture
right from this text.
Power saving function
The HDM97Pocket switches off automatically if the battery is empty. If enabled, it also switches off after a
specified time if one of the conditions listed below becomes true for the specified time period.
•In pressure mode: The value remains 0 for the specified time period
•In conductivity mode: The conductivity is 0 µs/cm for the specified time period
•In pH mode: The pH probe is not connected for the specified time period
The HDM97Pocket does not switch off when one of the conditions below are met
•A computer is connected to the meter
•The TIMER / stopwatch is running, regardless if displayed or hidden.
Displaying battery charge progress and finish
If the battery is being charged the symbol at the left top corner in the display is animated in 4 steps. There is
a delay of one second displaying each step. After the last step has been displayed the animation starts from
again like illustrated in the picture below.

Battery gauge display during operation
If nothing is connected to the USB port during operation the internal battery is used to supply power to the
instrument. The battery symbol in the left top corner of the display shows the remaining capacity of the
internal battery. The combinations have the meanings listed below:
The battery is 100% full.
The battery has approx. 2/3 of its capacity left.
The battery has approx. 1/3 of its capacity left.
The battery is empty, approx 10% is left.
If this symbol starts flashing the battery is totally empty and the meter will switch
off shortly.
Battery aging
The battery technology of the HDM97Pocket is based on Lithium-Ion-Polymer technology. This technology
has many advantages compared with Nickel-Metal-Hydride technology which are lower weight, smaller size,
longer life, no memory effect and higher efficiency. However, after a couple of years (5 years estimated) the
battery's capacity will start decreasing.
Battery replacement –ONLY BY MANUFACTURER
Do not try to replace the battery by yourself. The battery is mounted directly onto the main PCB inside the
HDM97Pocket, and the main PCB itself contains the battery protection circuit. If the battery is not handled in
the right way, there is extremely danger of fire and explosion. Therefore, this battery can only be replaced
from IBP personnel who have run through a special training in handling Lithium-Ion batteries.

Value adjustment
The adjustment of values is done via the navigation keys and . By pressing and holding down
one of these keys the last (right) digit of the value will be incremented or decremented depending on the key.
If this digit reaches the boundary it remains 0 and the next digit will begin to change. If the key is being
released and pressed again the procedure will start again beginning with the last digit.
Example showing a value, which has an allowable range from 0.00 to 7.50:
Display: 0.00 ; navigationkey is hold down:
Order of value incements (every change follows with a delay of 0.3 seconds):
0.01→0.02→0.03→0.04→0.05→0.06→0.07→0.08→0.09(carry-over)
0.10→0.20→0.30→0.40→0.50→0.60→0.70→0.80→0.90 (carry-over)
1.00→2.00→3.00→4.00→5.00→6.00→7.00→7.50 (Max value reached)
If the value will exceed the range limits (in this case from 7.00 to 8.00) the value will be truncated to the
maximum allowed value, 7.50 in this particular example. The Symbol will become blank and the
meter does not react on the corresponding navigation key. The values can only be changed down to 0.00
using the other key.
