This instrument is compliant with safety standard IEC 61010- 2-030, for voltages up to 5V with respect to ground. Failure to observe the safety instructions may result in electric shock, re, explosion, and destruction of the instrument and of the installations. The operator and/or the responsible authority must carefully read and clearly understand the various precautions to be taken in use. Sound knowledge and a keen awareness of electrical hazards are essential when using this instrument. Observe the conditions of use, namely the temperature, the relative humidity, the altitude, the degree of pollution, and the place of use. Do not use the instrument if it seems to be damaged, incomplete, or poorly close. Before each use, check the condition of the insulation on the leads, housing, and accessories. Any item of which the insulation is deteriorated (even partially) must be set aside for repair or scrapping. Do not make measurements on bare live conductors. Use a non-contact sensor or a sensor that provides the necessary electrical insulation. Always wear personal protective equipment (PPE), in particular insulating gloves, if there is any doubt or it is impossible to measure the voltage levels to which the temperature sensor is connected. All troubleshooting and metrological checks must be done by competent, accredited personnel. CONTENTS
