1 Introduction
QuantumX is a modular data acquisition system from
HBM for demanding measurement and test functions.
The different inputs acquire mechanical, electrical, hy
draulic and thermal measurands, such as force, strain,
torque, pressure, displacement, temperature, rotational
speed, acceleration, position, flow rate, voltage, etc.
The MX403B voltage measurement module can measure
voltages as high as 1000 V, as well as small differential
voltages at high electric potential.
The QuantumX family documentation basically com
prises:
SThe current operating manual for the voltage meas
urement module (available in printed form)
SA quick start guide for initial start-up (available in prin
ted form)
SData sheets for the individual modules and accessor

Note
When working with the MX403B, always take note of the
standard operating manual (I2322) as well.
The high level of protection of the MX403B is guaranteed
by consistent development in accordance with the latest
conditions specified in the measuring equipment stand
ards IEC 61010-1:2010+Cor.:2011 and
IEC 61010-2-030:2010+Cor.:2011, as well as by VDE
certification and production monitoring.
The MX403B has four insulated differential measurement
channels for directly measuring voltages up to 1000 V DC
or 1000 V rms AC.
The different measuring ranges allow the acquisition of
high voltages to remote ground, as well as the measure
ment of small differential voltages at high potential to re
mote ground.
The connection is made with 4 mm safety lab jacks,
19 mm pitch, suitable for standardized BNC adapters.
Each channel is equipped with a programmable amplifier,
analog reconstruction and antialiasing filters, a 24bit
ADC and digital filters.

2 Safety instructions
This measurement module is built and tested in accord
ance with EN 61010, Safety Requirements for Electrical
Equipment for Measurement, Control and Laboratory
Use, and was in perfect condition when it left production.
To maintain this condition and ensure risk-free operation
(reducing residual risks, EN 610101:2010 17 c), the user
must comply with the instructions and warning notices
contained in this operating manual.
2.1 Warning signs and danger symbols
Important instructions for your safety are specifically iden
tified. It is essential to follow these instructions in order to
prevent accidents and damage to property.
DANGER
This marking warns of an imminently threatening danger
ous situation which - if safety requirements are disregarded
- will result in death or serious physical injury.
Note
This marking draws attention to a situation which - if dis
regarded - can result in damage to property.

2.1.1 Symbols on the measurement module
Take details in the operating manual into account
Read and comply with the operating manual.
2.2 Proper use
The MX403B voltage measurement module fits perfectly
into the modular QuantumX series and is solely used to
measure high differential voltages or differential voltages
at high potential to remote ground, within the ratings
stated in the specifications.
The device is not intended for use as a safety compon
ent. Please also refer to the section: "Additional safety
precautions".
Proper and safe operation requires proper transportation,
correct storage, siting and mounting, and careful opera
tion.
Everyone involved with siting, starting up, or operating
the measurement module must have read and under
stood the operating manual and in particular the technical
safety instructions.
In the interests of safety, the measurement module
should only be operated by qualified personnel (see be
low) and as described in the operating manual. It is also
essential to comply with the legal and safety require
ments for the application concerned during use. The
same applies to the use of accessories.

DANGER
If the measurement module is not used as intended, the
protection provided by the measurement module may be
impaired.
DANGER
If the measurement module is used outside the ratings,
the protection provided by the measurement module may
be impaired.

2.3 Measurement categories
The MX403B is designed for applications in measure
ment categories CAT II and CAT III:
CAT II
Measurement category II is applicable to test and meas
uring circuits that are directly connected to the user con
nections (sockets) of the low-voltage grid installation. It is
expected that this part of the installation will have at least
three levels with overload protection elements between
the transformer and the measuring circuit connection
point.
CAT III
Measurement category CAT III is applicable to test and
measuring circuits that are connected to the distribution
circuit of the building low-voltage grid installation. It is ex
pected that this part of the installation will have at least
two levels with overload protection elements between the
transformer and the measuring circuit connection point.

DANGER
For all other applications at the low-voltage installation
there is a risk related to:
SElectric shock
SArc flash burns
SArc blast explosion and
SOther phenomena
The MX403B is only suitable for rated voltages within the
measurement categories described - the MX403B is not
suitable for any other applications at the low-voltage in
stallation and its use here is not permitted.
Outside the measurement categories
The following applies to test and measuring circuits
without a rated measurement category (formerly CAT I):
Whether the MX403B is suitable for test or measuring
circuit applications not intended for direct connection to
the supply network can only be determined by an accur
ate analysis of the operating voltage, peak voltage, loop
impedance, occasional overvoltage and transient over
voltage of these circuits. The following characteristics
apply to the MX403B in this respect:
SPeak voltage: max. 1250 V
SLoop impedance: min. 100 m
(see EN 61010-2-030:2011 Table AA.1)
SOccasional overvoltage: none
STransient overvoltage: "3000 V
