FADMAN The perfect all-around tool for working with anything electrical. Very useful for debugging electrical problems including small power wires, car components, small electrical circuits, and more. Automatic shut off after a while of no usage to save on batteries. Perfect for Hobbyists, DIY Projects, Students, Engineers, Repairing Works Failing these Precautions may Lead to Instrument Damage Please do not try and measure voltages or currents beyond what is supported for safety concerns. Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, diodes, or capacitance. Use the proper terminals, function, and range for your measurements. Before measuring current, check the meter's fuses and turn power off to the circuit before connecting the meter to the circuit. Before rotating the range switch to change functions, disconnect test leads from the circuit under test. Before attempting to insert transistors for testing, always be sure that the test leads have been disconnected from any measurement circuits. Remove test leads from the meter before opening the Meter case. The instrument can only be used in conjunction with the probe for compliance with safety standards. If the probe needs replacing due to damage, the replacement must be of the same type or the same electrical specification Always make sure the Test Probes are fitted in the correct sockets (Especially while measuring AC Voltage) Classification PRODUCT TYPE - Digital Multimeters
