The design of the product complies with safety class 1. Use only a domestic mains socket (100 - 240 V~) of
the public power supply network to power the unit.
The mains socket must be close to the device and easily accessible, or an emergency kill switch device
must be present.
Measuring devices and devices connected to the power supply should be kept out of the reach of children.
Therefore, be especially careful when children are around.
First, connect the measurement cable to the oscilloscope; then connect the probe to the signal measuring
circuit to be tested. After finishing the measurements, first disconnect the measure ment leads from the
circuit before you disconnect the cable from the oscilloscope.
Be especially careful when dealing with voltages higher than > 50 V alternating current (AC) or > 75 V direct
current (DC)! Even at such voltages you can get a life-threatening electric shock if you come into contact
with live electric wires.
Check the measuring device and its measuring leads for any damage before each measurement. Never take
any measurements if the protecting insulation is defective (torn, missing etc.).
To avoid electric shock, do not touch the connections/measuring points directly or indirectly during
measurements.
Never reach beyond the grip surface of the probes during a measurement process. There is danger of a
life-threatening electric shock.
Do not use the device shortly before, during, or after a thunderstorm (lightning! / high-power surges!). Make
sure that your hands, shoes, clothing, the floor, the measuring device and/or measuring lines, the circuits
and its parts are always dry.
Do not use the device in rooms or under unfavourable ambient conditions in which there are or could be
combustible gases, vapours or dust.
Do not use in the immediate vicinity of:
- strong magnetic or electromagnetic fields
- transmitting aerials or HF generators.
- These can affect the measurement.
Use only measurement lines and accessories for the measurement that match the specifications of the
oscilloscope.
If a safe operation can no longer be assumed, the device must be put out of operation and secured against
unintended operation. Safe operation can no longer be assumed if:
- the device is visibly damaged,
- the device does not function any more and
- the device was stored under unfavourable conditions for a long period of time or
- it has been subjected to considerable stress during transportation.
Never switch the device on immediately after having taken it from a cold to a warm environ ment. The
condensation that forms might destroy your device. Allow the device to reach room temperature before
switching it on.
Never disassemble the product! There is danger of a life-threatening electric shock!
Do not carelessly leave the packaging material lying around, since it could become a dangerous plaything
for children.
The device is intended only for dry interior rooms (not bathrooms or similar damp rooms). The device must
not get wet or damp. There is danger of a life-threatening electric shock!
On industrial sites, the accident prevention regulations of the association of the industrial workers' society for
electrical equipment and utilities must be followed.
