Voltage Warnings Use the meter as specified in the manual otherwise the protection offered by the multimeter may be impaired Do not use the multimeter with back cover opened it may cause electric shock Set to a proper range for your measurement Check the test leads for any damaged insulation or broken wires Insert red and black test leads into proper input terminals and ensure good contact between them Do not input signal beyond the rated values of the multimeter otherwise it may cause electric shock or damage to the multimeter Prohibit switching the range during the voltage or current measurement for it may cause damage to the multimeter Please use replacement parts with the same model or similar electrical specifications To avoid electric shock Do not apply any voltage above 600V between COM and grounding Please take caution when working voltage goes above 60VDC or 30VAC RMS To ensure the accuracy please replace the batteries as soon as 1 appears Shut off the power timely after the measurements complete Take out the batteries if not used for a long time Do not use the multimeter in places exposed to high temperature high moisture The performance of the multimeter may be compromised if moisture affected To prevent damage to the multimeter or personal injury do not alter internal wiring randomly Clean the multimeter casing with slightly damped soft cloth and mild agent Do not use any abrasives and corrosives International Electrical Symbols s A C _L Grounding Low Battery Indication Warning DC AC Double Insulated Diode Buzzer Conforms to European Union
