1.1 Proper use
The MultiHandy 2025 measuring instrument is a mo-
bile hand-held device for measuring and recording.
The measurement data is recorded by sensors con-
nected to the measuring instrument. A number of sen-
sors can be connected to the measuring instrument
for different measurements.
Any other use of the measuring instrument is consid-
ered improper.
See also Technical data, page 21.

INSTRUMENT
This section describes the scope of delivery, connec-
tions, keys and the display of the measuring instru-
ment.
2.1 Measuring instrument case
Measuring instrument case:
• 1 MultiHandy 2025
• 1 USB cable
• 1 power supply for USB cable with country adapter
• 2 ISDS pressure sensors with 2.5 m cable
• 2 MINIMESS direct connections
• 1 carrying strap set (including fastening eyelets)
• 1 Quick Guide
• 1 General Safety Informations and Warnings
2.2 Measuring instrument
The MultiHandy 2025 is a dual-channel measuring in-
strument which provides the user with all functions
needed for professional and challenging metrology.
When using sensors with ISDS (intelligent sensor de-
tection), the measuring instrument automatically iden-
tifies the connected sensors during switch-on and
adopts all parameters: Measurement range, physical
measurement variables, unit of measurement, output
signal and characteristic curve (linearisation).
This prevents sensors from getting mixed up. Manual
entry of a variety of data is unnecessary.
When using sensors without ISDS, sensor parame-
ters must be entered manually.
The measuring instrument is operated via 4 function
keys and a menu key.
Up to two sensors can be connected simultaneously
on one measuring instrument. Moreover, a special
channel provides the option of making calculations.

The instrument is equipped with an internal memory.
Up to 5 measurement series with up to 60,000 meas-
urement points each can be saved in the measuring
instrument.
You can connect the measuring instrument to a PC
and charge it using the USB interface. We recom-
mend the HYDROlink6 software for downloading the
measurement data. Alternatively, you can use the
HYDROcom6 software.
2.3 Rear side
Battery compartment
The measuring instrument is delivered with two re-
chargeable AA mignon cells. The capacity is sufficient
for an entire day of measurement.

7.2 Configuring channel
If you are using a sensor without ISDS, you have to
configure a channel. You need a corresponding pa-
rameter for the sensor. They are on the sensor or in
the sensor data sheet.
The measuring instrument only detects ISDS sensors
when the measuring instrument is being switched on.
You can configure an ISDS sensor manually if you do
not connect it until the measuring instrument is
switched on.
You must define the following parameters during the
configuration:

Measurement variables and units of measurement
You can configure sensors for the following measure-
ment variables and units of measurement.
Signal type, signal range and Range
You can configure sensors for various signal types
and signal ranges. Make sure that the signal type
matches the selected measurement variable.
The range can have the following meaning depending
on the signal type:
• Measurement range
• Calibration value
The following table shows signal types and the corre-
sponding meaning of the range:
Measurement range
The measurement range is specified for the signal
range. You must enter the upper and lower limit.
Every limit value is a number and is entered as five
characters. The first character can be a minus sign.
Digits or periods (correspond to commas) are also
characters.
Examples for limit values:
•
-9999
• -2.50
• 60.00
• 99999
Calibration value
The calibration value is a number and is entered as
five characters. The first character can be a minus
sign. Digits or periods (correspond to commas) are
also characters.
Examples for calibration values:
• Gear wheel volumetric flow sensor
Quantity per spaces between cogs
• Turbine volumetric flow sensor
Flow rate at 1000 Hz
• RPM sensor

8.3 Display rate
You can use the Disp.rate setting to change the dis-
play rate. The display rate determines at which inter-
vals the measurement values are updated on the dis-
play. You can choose between 1 second and
500 milliseconds.
The shorter the display rate, the more unstable the
measurement values appear in the display.
Do not confuse the display rate with the measurement
rate at the signal input and the scanrate of a measure-
ment series.

DEVICE menu and use [F1] to select
