VOLTCRAFT 124455 VC135 Consignes De Sécurité page 4

Do not exceed the maximum permitted input values. Do not contact circuits or
parts of circuits if there could be voltages higher than 25 V ACrms or 35 V DC
present within them. Mortal danger!
Before measuring, check the connected measuring lines for damage such as,
for example, cuts, cracks or squeezing. Defective measuring cables must no
longer be used. Mortal danger!
During measuring, do not grip beyond the tangible grip range markings
present on the test prods.
You may only connect the two measuring leads to the measuring device
that are required for measuring operation. Remove all measuring leads not
required from the device for safety reasons.
c) Voltage measuring "V"
• Before measuring voltages, always make sure that the measuring instrument is
not set to a measuring range for current.
d) Current measuring (A , only in VC155)
• The voltage in the measuring circuit may not exceed 600 V.
• Measuring operations of >5 A may only be performed for at most 10 seconds with
a subsequent measuring pause of 15 minutes.
• All current measuring ranges are provided with fuses and thus protected against
overload.
• AC current is not supported by this DMM. Do not attempt to measure AC currents
with this DMM.
Insert the red measuring lead into the 10 A max socket if you are not
sure about the size of the current.
e) Resistance measuring
• Make sure that all the circuit parts, switches and components and other objects of
measurement are disconnected from the voltage and discharged.
f) Diode test
• Make sure that all the circuit parts, switches and components and other objects of
measurement are disconnected from the voltage and discharged.
g) Non contact voltage test "NCV"
• Make sure that all measuring sockets are unoccupied. Please remove all
measuring leads and adapters from the measuring device.
• This function only serves as aid. Prior to performing work on these cables, you
have to perform contact measuring operations to check for the absence of voltage.
h) Temperature measuring (only in VC155)
• Make sure that all measuring sockets are unoccupied. Please remove all
measuring leads and adapters from the measuring device.
• This function only serves as aid. Prior to performing work on these cables, you
have to perform contact measuring operations to check for the absence of voltage.
i) Maintenance and cleaning
• Never operate the measurement device when it is open. RISK OF FATAL
INJURY!
• Regularly check the technical safety of the instrument and measuring lines, e.g.
check for damage to the housing or squeezing etc.
j) Cleaning
• Live components may be exposed if covers are opened or parts are removed.
• The connected lines must be disconnected from the measuring device and all
measuring objects prior to cleaning or repairing the device. Switch the DMM off.
• Do not use any carbon-containing cleaning agents or petrol, alcohol or the like to
clean the product.
• These could corrode the surface of the measuring instrument. Furthermore, the
fumes are hazardous to your health and explosive. Moreover, you should not use
sharp-edged tools, screwdrivers or metal brushes or similar for cleaning.
k) Fuse replacement (only for VC155)
• Using mended fuses or bridging the fuse holder is not admissible for safety
reasons.
• Never operate the measurement device when it is open. RISK OF FATAL
INJURY!
l) Inserting/replacing the battery
• Do not leave flat batteries in the device. Even batteries protected against leaking
can corrode and thus release chemicals which may be detrimental to your health
or destroy the battery compartment.
• Do not leave batteries lying around carelessly. They might be swallowed by
children or pets. If swallowed, consult a doctor immediately.
• If the device is not used for longer periods of time, remove the batteries in order
to prevent leaking.
• Leaking or damaged batteries might cause acid burns when getting into contact
with skin. Therefore, use suitable protective gloves.
• Make sure that the batteries are not short-circuited. Do not throw batteries into
fire! Batteries may not be recharged. Danger of explosion!
m) Troubleshooting
• Repairs other than those described should only be carried out by an authorised
specialist.
