The Fluke 12 Digital Multimeter is designed to support first level electrical and electronic troubleshooting. Their compact design, slide-switch and pushbutton controls allow true one-hand operation. V Chek simplifies safe power source and supply measurement. When measuring ohms/continuity with more than 4.5 volts present across the input jacks (intentional or not), the meter automatically switches to measuring ac or dc volts, whichever is greater. Input impedance is approximately 2 k-ohm, helping determine if voltage is from leakage or a hard connection. Overload protection is provided if the circuit is checked in ohms mode. Continuity Capture locates intermittent opens and shorts as brief as 250 us, and identifies them in a symbolic display. Min/Max recording with relative time clock, records highest and lowest voltage readings during a 100-hour period. Features. 4000 Count Digital Display. Diode Test. Fast Continuity Beeper. Sleep Mode.
