EXPLANATION OF THE SYMBOLS
An exclamation mark within a triangle indicates important information
contained within this technical product documentation which must be
observed.
A lightning symbol inside a triangle warns against the danger of an electric
shock or impairment of the electrical safety of the device.
The arrow symbol is used when specic tips and advice on operation are
provided
Protection class 2 (double or reinforced insulation/ protective insulation)
CAT I
Measurement Category I Overvoltage category for measuring circuits of
electrical and electronic equipment that is not directly supplied with mains
voltage (e.g., battery-operated devices, protective extra-low voltage, signal
and control voltages, etc.).
CAT II
Measurement Category II Overvoltage category for measuring electrical
and electronic devices that are directly supplied with mains voltage via a
mains plug. This category also covers all smaller categories (e.g., CAT I for
measuring signal and control voltages).
CAT III
Measurement Category III (Overvoltage category) for measuring in building
installation (e.g., outlets or sub-distribution). This category also covers
all smaller categories (e.g., CAT II for measuring electronic devices). The
measuring operation in CAT III is permitted only with probe tips with a
maximum free contact length of 4 mm or with cover caps over the probe tips.
CAT IV
Measurement Category IV (Overvoltage category) for measuring at the
origin of the low-voltage installation (e.g., main distribution, electricity
provider's transfer points to homes, etc.) and outdoors (e.g., tasks on earth
line, overhead line, etc.). This category also contains all lower categories.
The measuring operation in CAT IV is permitted only with probe tips with a
maximum free contact length of 4 mm or with cover caps over the probe tips.

INTENDED USE
• The digital oscilloscope is intended to be used for visualising electrical magnitudes and sig-
nals.
• There are four independent input channels available for measurement
• The measuring lead is connected to the oscilloscope via two BNC sockets.
• Measurement and display of the electrical variables in the range of measurement category
CAT II of up to max. 300V RMS (probe setting 10×) at an input impedance of 1 M Ohm / 20 pF
against ground potential as well as all lower measuring categories.
• The bandwidth and the sampling rate depend on the type, as follows:
- DSO-1084x 80 MHz at 1 GS/s
- DSO-1104x 100 MHz at 1 GS/s
- DSO-1204x 200 MHz at 1 GS/s
- DSO-1254x 250 MHz at 1 GS/s
• DSO-1xx4F is also equipped with a frequency generator
• Multifunctional generator for various signal forms such as sine (up to 25 MHz), rectangle (up
to 10 MHz), ramp (up to 1 MHz), EXP (rise/fall to 5 MHz)
• Sampling rate of 200 MS/s
• vertical signal resolution of 12 bits
• Output voltage range: 5 mVss to 3.5 Vss (50 Ω); 10 mVss to 7 Vss (high impedance)
The maximum correlated input quantities indicated on the device must never be exceeded.
The measuring instrument is operated with a voltage between 100 - 120 V AC at 45 - 440 Hz
and 120 - 240 V AC at 45 - 60 Hz.
The measuring instrument must not be operated when open.
Do not make measurements in potentially explosive areas (Ex) or wet rooms or under
unfavourable
ambient conditions. Unfavourable ambient conditions are: Moisture or high humidity, dust and
ammable gases, fumes or solvents, as well as thunderstorms or thunderstorm conditions like
strong electrostatic elds etc.
For safety reasons, when measuring only use measuring cables or accessories which are
adjusted to the specications of the meter.
The instrument should only be operated by persons who are familiar with the required regula-
tions and potential dangers. The use of personal protective equipment is recommended.
Use other than that described above can lead to damage to the product and may involve
additional risks such as, for example, short circuits, re, electrical shocks, etc. No part of the
product may be modied or recongured!
The safety instructions are to be observed without fail!
SAFETY INSTRUCTIONS
Please read the entire manual before using the device as it contains
important information for proper operation.
The warranty will be void in the event of damage caused by failure to
observe these safety instructions! We do not assume any liability for
any resulting damage!
We shall not accept liability for damage to property or personal injury
caused by incorrect handling or non-compliance with the safety
instructions! The warranty/guarantee will be void in such cases.
This device has left our factory premises in a safe and perfect condition.
We kindly request the user to observe the safety instructions and warnings contained
in the enclosed operating instructions so this condition is maintained and to ensure
safe operation.
• For safety and approval reasons, unauthorised conversion and/or modications to the prod-
uct are not permitted.
• If you have doubts about how the device should be operated or how to connect it safely,
consult a trained technician.
• Measuring instruments and their accessories are not toys and should be kept out of the
reach of children!
• On industrial sites, the accident prevention regulations of the association of the industrial
workers’. society for electrical equipment and utilities must be followed.
• Measurement instruments used at schools, training facilities, do-it-yourself and hobby work-
shops should not be handled unless supervised by trained, responsible personnel.
• First, connect the measurement cable to the oscilloscope; then connect the probe to the
signal measuring circuit to be tested. After nishing the measurements, rst disconnect the
measurement leads from the circuit before you disconnect the cable from the oscilloscope.
• Take particular care when dealing with voltages exceeding 30 V AC or 30 V DC! Even at
these voltages, there is a danger of fatal electric shock if you touch electric conductors.
• To avoid electric shock, do not touch the connections/measuring points directly or indirectly
during measurements. During measuring, do not grip beyond the tactile grip range markings
on the test probes.
