Easy-to-use circuit analysis: checks for various wiring conditions correct wiring, voltage drop under a full load condition, no ground. Product details: weighs 9. 4 oz 267g. We’ve been committed to the craft and its craftsmen for over 100 years.
Gives access to measurements of line voltage, polarity reversal, ground-neutral voltage and line impedances. Super bright display: 128 x 64 oled display with backlight and large, easy-to-read numbers so you can always see the correct reading. Measures voltage drop under 12, 15 and 20-amp loads. Personal shock hazards stem from poor grounding, and/or no ground fault protection.

By interpreting the waveforms displayed on the screen, technicians can diagnose a wide range of electrical problems, and control modules, such as those produced by sensors, such as voltage drops, intermittent connections. For example, such as an engine, a mechanic might activate the fuel pump to see if it is delivering fuel to the engine, or activate the air conditioning system to check for proper operation.
Plus, van, the built-in flashlight is bright enough to illuminate your work area. Activating a componenttypically refers to the process of turning on or engaging a particular part of the car's system, a fuel pump, or an electrical component. The name "multimeter" comes from its ability to measure multiple electrical properties, capacitance, including voltage, resistance, current, diode test and continuity. It can be used to test for voltage, short circuits, and continuity, and can help identify problems such as bad grounds, resistance, and open circuits.
