6. Safety information
These instructions contain important information on how to use the device correctly. Please read them care-
fully before using the device 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 to avoid damaging the device, always observe the safety information and
warnings in these instructions.
• The unauthorised conversion and/or modification of the product is inadmissible for reasons of safety and
approval (CE).
• Consult an expert when in doubt about the operation, safety or connection of the device.
• The measurement device and its accessories are not toys and must be kept out of the reach of children.
• For installations in industrial facilities, follow the accident prevention regulations for electrical systems
and equipment issued by the national safety organisation or the corresponding national authority.
• In schools, educational facilities, hobby and DIY workshops, measuring devices must be operated under
the responsible supervision of qualified personnel.
• The voltage between the connection points of the measuring device and earth potential must not exceed
250 V (DC/AC) in CAT III.
• When using test leads without protective caps, measurements between the measuring device and the
earth potential must not exceed the CAT II measurement category.
• When taking CAT III measurements, the protective caps must be placed on
the probe tips to avoid accidental short circuits.
• Push the protective caps onto the probe tips until they click into place. To
remove the caps, pull them off the tips with some force.
• Always remove the probe tips from the measured object before changing
the measurement range.
• 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.
• Check the measuring device and test leads for signs of damage before each measurement. Never take
measurements if the protective insulation is damaged (torn, missing, etc.). Measuring cables have a wear
indicator. The 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.
