Damages resulting from failure to observe these safety precautions are exempt from any legal claims whatever.
General:

• Read these operating instructions carefully and make them available to subsequent users.
• It is essential to observe the warning notices on the device, do not cover or remove them.
• Pay attention to the use of the multimeter and only use it in the suitable overvoltage category.
• Familiarize yourself with the functions of the measuring device and its accessories before you carry out the first measurement.
• Do not operate the measuring device unsupervised or only protected against unauthorized access.
• Use the multimeter only for the purpose of its determination and pay particular attention to warning notices on the device and information on the maximum input values.

Electric safety:

• Voltages over 25 VAC or 60 VDC are generally considered dangerous voltages.
• Only work on dangerous voltages by or under the supervision of qualified personnel.
• When working on dangerous voltages, wear suitable protective equipment and observe the relevant safety rules.
• Do not exceed the maximum permissible input values under any circumstances (risk of serious injury and / or destruction of the device)
• Pay special attention to the correct connection of the test leads depending on the measuring function in order to avoid a short circuit in the device. Never apply a voltage in parallel to the current sockets (A, mA, µA).
• Current measurements are always carried out in series with the consumer, i.e. with the supply line disconnected.
• Remove the test probes from the measurement object before changing the measuring function.
• Never touch the bare test probes during the measurement, only hold the test leads by the handle behind the finger guard. If applicable, discharge any capacitors before measuring the circuit to be measured.
• The thermocouple for temperature measurements is made of conductive material. To avoid electric shock, never connect it with a live conductor.

Measurement environment:

• Avoid any proximity to explosive and flammable substances, gases and dust. An electric spark could lead to an explosion or deflagration – danger to life!
• Do not carry out measurements in corrosive environments, the device could be damaged or contact points inside and outside the device could corrode.
• Avoid working in environments with high interference frequencies, high-energy circuits or strong magnetic fields, as these can negatively affect the multimeter.
• Avoid storage and use in extremely cold, humid or hot environments, as well as long-term exposure to direct sunlight.
• Only use devices in damp or dusty environments in accordance with their IP protection class.
• If no IP protection class is specified, only use the device in dust-free and dry indoor rooms only.
• When working in damp or outside areas, pay particular attention to completely dry handles on the test leads and test probes.
• Before starting the measuring operation, the device should be stabilized at the ambient temperature (important when transporting from cold to warm rooms and vice versa)

Maintenance and Care:

• Never use the device if it is not completely closed.
• Before each use, check the device and its accessories for damage to the insulation, cracks, kinks and breaks. If in doubt, do not take any measurements.
• Change the battery when a battery symbol is displayed to avoid incorrect rdg.s.
• Switch off the multimeter before changing batteries or fuses and also remove all test leads and temperature probes.
• Replace defective fuses only with a fuse that corresponds to the original value. Never short-circuit a fuse or fuse holder.
• Charge the battery or change the battery as soon as the battery symbol lights up. Insufficient battery power can lead to inaccurate measurement results. Electric shocks and physical damage can result.
• If you are not going to use the device for a longer period of time, remove the battery from the compartment.
• Have maintenance and repair work on the multimeter carried out only by qualified specialists.
