An electric spark could lead to an explosion or deflagration – danger to life! Avoid any proximity to explosive and flammable substances, gases and dust.To avoid electric shock, never connect it with a live conductor. The thermocouple for temperature measurements is made of conductive material.If applicable, discharge any capacitors before measuring the circuit to be measured. Never touch the bare test probes during the measurement, only hold the test leads by the handle behind the finger guard.Remove the test probes from the measurement object before changing the measuring function.Current measurements are always carried out in series with the consumer, i.e.Never apply a voltage in parallel to the current sockets (A, mA, ♚). 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.Do not exceed the maximum permissible input values under any circumstances (risk of serious injury and / or destruction of the device).When working on dangerous voltages, wear suitable protective equipment and observe the relevant safety rules.Only work on dangerous voltages by or under the supervision of qualified personnel.Voltages over 25 VAC or 60 VDC are generally considered dangerous voltages.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.Do not operate the measuring device unsupervised or only protected against unauthorized access.Familiarize yourself with the functions of the measuring device and its accessories before you carry out the first measurement.Pay attention to the use of the multimeter and only use it in the suitable overvoltage category.It is essential to observe the warning notices on the device, do not cover or remove them.Read these operating instructions carefully and make them available to subsequent users.Damages resulting from failure to observe these safety precautions are exempt from any legal claims whatever. To ensure safe operation of the equipment and eliminate the danger of serious injury due to short-circuits (arcing), the following safety precautions must be observed. main-switches on current input, overvoltage-diverter, current use counter. CAT IV: Units and installations, which are supplied overhead lines, which are stand in a risk of persuade of a lightning, i.e.CAT III: Distribution level, fixed installation, with smaller transient overvoltage’s than CAT IV.CAT II: For local level, appliances, main wall outlets, portable equipment. CAT I: For signal level, telecommunication, electronic with small transient over voltage.
