Safety Information - VOLTCRAFT VC281 TRMS Bedienungsanleitung

5. Safety information

These instructions contain important information on how to use the multimeter correctly. Please
read them carefully before using the multimeter for the first time.
Damage caused due to failure to observe these instructions will void the warranty. We shall not be
liable for any consequential damage.
We shall not be liable for damage to property or personal injury caused by incorrect handling or
failure to observe the safety information! Such cases will void the warranty/guarantee.
• This device was shipped in a safe condition.
• To ensure safe operation and avoid damaging the device, always observe the safety information and
warnings in these instructions.
• The unauthorised conversion and/or modification of the device is not permitted for safety and approval
reasons.
• Check that the measuring device is functioning correctly with a known source before using it.
• Consult a technician if you are not sure how to use or connect the device.
• Measuring instruments and their accessories are not toys and must be kept out of the reach of children.
• Always comply with the accident prevention regulations for electrical equipment when using the product
in commercial facilities.
• In schools, educational facilities, hobby and DIY workshops, the multimeter must be used under the
responsible supervision of qualified personnel. The same applies when the multimeter is used by people
with reduced physical and mental capabilities.
• Always ensure that the multimeter is set to the correct measurement mode before taking a measurement.
• When using measuring probes without protective caps, measurements be-
tween the multimeter and the earth potential must not exceed the CAT II
measurement category.
• When taking CAT III measurements, the cover caps must be placed on the
probe tips (max. length of exposed contacts = 4 mm) to avoid accidental
short circuits. These are supplied with the device.
• Always remove the measuring probes from the measured object before changing the measurement
range.
• The voltage between the multimeter connection points and earth must never exceed 600 V DC/AC in
CAT III.
• Exercise particular caution when working with voltages higher than 33 V (AC) and 70 V (DC). Touching
electrical conductors with these voltages may cause a fatal electric shock.
• To prevent an electric shock, do not touch the connections/measuring points when taking measurements,
either directly or indirectly. When taking measurements, do not touch any exposed areas beyond the grip
markings on the measuring probes and the clamp transformer.
• Check the multimeter and test leads for signs of damage before each measurement. Never take meas-
urements if the protective insulation is damaged (torn, missing, etc.). The test leads come with a wear
indicator. A second layer of insulation will become visible if the lead is damaged (the second layer of
insulation is a different colour). If this occurs, discontinue use and replace the measurement accessory.
