Conrad VC-608 Bedienungsanleitung Seite 52

After changing the fuses, close the casing and screw it carefully together in rever-
se order. Switch the device on again after the housing has been closed and scr-
ewed in securely.
• Be particularly careful when dealing with alternating voltages greater than 25 V -
(AC) or direct voltages greater than 35 V (DC). Even at these voltages, you can
receive an extremely dangerous electric shock by touching electrical leads. There-
fore, switch off the voltage source to start with, connect the measuring device with
the connections of the voltage source to be measured, tune the measuring device
to the requisite voltage-measuring range and subsequently switch on the voltage
source. After completing the measurement, switch off the voltage source and
remove the sensing leads from the connections to the voltage source.
• Before every measurement of voltage, ensure that the measuring device is located
in the voltage-measuring range.
• The sensors must be removed from the object which has been measured, before
every change of measuring range.
• Before taking any measurement, check your measuring device or your sensing
leads for damage.
• Only use sensing leads for taking measurements, which have been supplied with
the measuring device. Only these leads are permissible.
• In order to avoid an electric shock, take care that the sensors and the connections
to be measured (measuring points) are not touched while measuring, even indirec-
tly.
• The voltage running between the measuring device and earth must never exceed
1,000 V (DC) or 750 V (DC) rms.
• Do not work with the measuring device in rooms where combustible gases, steam
or dust are present or could be present; nor in adverse environmental conditions.
For your own safety, strictly avoid the measuring device or measuring cables
becoming damp or wet. During operation, avoid being close to:-
a) strong magnetic fields (loudspeakers, magnets)
b) electromagnetic fields (transformers, motors, coils, relays, fuses, electromagnets,
etc.)
c) electrostatic fields (charging / discharging)
