- Page 2 This manual contains information and warnings that must be followed for operating the meter safely and maintaining the meter in a safe operating condition. If the meter is used in a manner not spe cified by the manufacturer, the protection provided by the meter may be impaired. identifies conditions and actions that could result in serious injury or even death to the user. identifies conditions and actions tha t could cause damage or malfunction in the instrument. To reduce the risk of fire or electric shock, do not expose this product to rain or moisture. The meter is intended only for indoor use. Keep your hands/fingers behind the hand/finger barrie rs (of the meter and the test probe assembly, where applicable) that indicate the limits of safe access of the hand held parts during measurements. Inspect lead wires, connectors, and probes for damaged insulation or exposed metal before using the meter. I f any defects are found, replace them immediately. Only use the probe assembly provided with the meter or a UL Listed Probe Assembly to the same meter ratings or better. IEC 61010031 requires exposed conductive test probe tips to be 4mm for CAT III & CAT IV ratings. Refer to the category markings on your probe assemblies as well as on the addon accessories (like detachable Caps or Alligator Clips), if any, for applicable rating changes. Observe proper safety precautions when working with voltages abov e 33 Vrms, 46.7 Vpeak or 70 VDC. These voltage levels pose a potential shock hazard to the user. Before and after hazardous voltage measurements, check the voltage function on a known source such as line voltage to determine proper meter functioning.

- Page 5 RMS (Root MeanSquare) is a term used to describe the effective or equivalent DC value of an AC signal. True RMS is the term which identifies a DMM that responds accurately to the effective RMS value regardless of the waveforms such as: square, sawtooth, triangle, pulse trains, spikes, as well as distorted waveforms with the presence of harmonics. Harmonics may cause : 1)Overheated transformers, generators and motors to burn out faster than normal 2)Circuit breakers to trip prematurely 3)Fuses to blow 4)Neutrals to overheat due to the triplen harmonics present on the neutral 5)Bus bars and electrical panels to vibrate Crest Factor is the ratio of the Crest (instantaneous peak) value to the True RMS value, and is commonly used to define the dynamic range of a True RMS DMM. A pure sinusoidal waveform has a Crest Factor of 1.414. A badly distorted sinusoidal waveform normally has a much higher Crest Factor.
- Page 6 automatically selects measurement function of DCV or ACV based , on their input levels via the test leads. The input also provides a low ramp up impedance (LoZ) to drain ghost voltages*. voltage threshold of 1V DC or AC up to the rated 1000V is present, the meter displays the voltage value in appropriate DC or AC, whichever larger in peak magnitude. Note: Ghostvoltages are unwanted stray signals coupled from adjacent hard signals, which confuse common multimeter voltage measurements. The mode provides low (ramp up) input impedance (approx. 2.1 to drain ghost voltages leaving mainly hard signal values on meter readin gs. It is an invaluable feature for precise indication of hard signals, such as distinguishing between hot and open wires (to ground) in electrical installation applications. *Only pushbutton features areavailable in AutoV mode.

A reading higher than that indicates a leaky diode (defective). A zero reading i ndicates a shorted diode (defective). An OL indicates an open diode (defective). Reverse the test leads connections (reverse biased) across the diode. The digital display shows OL if the diode is good. Any other readings indicate the diode is resistive orshorted (defective).
