UNI UT213A B C INSTRUCTIONS 4 Before measuring the function switch must be placed at the correct location and gears of range switch are not permitted to change during measuring so as to prevent the clamp meter damage 5 Do not apply DC600V AC600V or above voltage between the clamp meter terminal and grounding so as to prevent electric shock and clamp meter damage 6 When use the instrument to measure DC voltage of higher than 42V or AC RMS voltage of higher than 30V it is necessary to operate it carefully for there may be danger of an electric shock 7 Do not measure the voltage or current higher than the allowable input and the function range switch must be placed at the maximum range position when the range of the value to be measured is not determined Before measuring the resistance diode or circuit on off it is a must to cut off all the power supplies in the circuit and discharge all capacitors otherwise it may lead to incorrect measurement results 8 When the symbol of Q is displayed on the LCD it is necessary to timely replace the battery so as to assure the measuring precision Battery must be removed when the clamp meter was not used for a long time 9 Please do not change the internal wiring of the clamp meter at random to prevent instrument damage and insecurity 10 Do not keep or use the clamp meter in an inflammable and explosive environment with high temperature high humidity or strong electromagnetic field 11 During maintenance please clean the shell of the clamp meter with the soft cloth soaked with neutral detergent and do not use the abradant and solvent so as to prevent the shell corrosion instrument damage and insecurity 3 UT213A B C INSTRUCTIONS 12 the documentation shall indicate that probe assemblies to be used for MAINS measurements shall be RATED as appropriate for MEASUREMENT CATEGORY III or IV according to IEC 61010 031 and shall have a voltage RATING of at least the voltage of the circuit to be measured IV Electrical Symbols B Double insulation Grounding A Warning AC alternating current DC direct current n H Buzzer on off Diode Capacitance AC or DC alternating current or direct current A Danger high voltage ft This symbol signify the product comply with both USA and Canada requirement Meet EU European Union standards 4
