- 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 speci fied 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 that 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 barriers (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. If 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 add on accessories (like detachable Caps or Alligator Clips), if any, for applicable rating changes. Observe proper safety precautions when working with voltages above 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. Disconnect the test leads from the test points before changing functions. Eshop: www.emareg.cz Email: shop@emareg.cz...

- Page 5 RMS (RootMeanSquare) is a term used to describe the effective or equivalent DC value of an AC signal. True RMS is t he 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. Before and after hazardous voltage measurements, test the voltage function on a known source such as line voltage to determine proper meter functioning. Eshop: www.emareg.cz Email: shop@emareg.cz...
- 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*. n a signal above the 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 signal s coupled from adjacent hard signals, which confuse common multimeter voltage measurements. The mode provides low (ramp up) input impedance (approx. 2.1 voltages leaving mainly hard signal values on meter readings. 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 are available in AutoV mode.

- Page 8 Press the pushbutton momentarily to toggle H z function. It is only available to Voltage and Current related ranges. Input sensitivity varies automatically with the function range selected while activating the Hz function. 6V function range has the highest and the 1000V range has the lowest. When activated under DCV, ACV or VFD ACV voltage function, the trigger voltage range will be displayed right before starting the Hz readings. Press momentarily the button can manually select another trigger voltage range (not available to current ranges). It is recommended to first measure the signal voltage (or current) level and activate Hz function in that range to get the most appropriate trigger level. If the Hz reading becomes unstable, select lower sensitivity to avoid electrical noise. If the reading shows zero, select higher sensitivity.

A reading higher than that indicates a leaky diode (defective). A zero reading indicates 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 O L if the diode is good. Any other readings indicate the diode is resistive or shorted (defective).

- Page 15 Proper Rotation detection relies on solid signal connection to all three test lead terminals simultaneously. Any single disconnection will lead to detection failure and may produce false indication. To verify signal connection and hence proper meter indication, swap any two connects (to the meter) to check for meter indication of reverse movement Connect to the Motor as illust rated. Be sure the electricity supply is removed. From the perspective of looking down the shaft of the motor, speed spin it clockwise to generate sufficient signal strength for proper meter detection. If the meter indicates a clockwise movement, the motor leads connected to L1, L2 and L3 of the meter are L1, L2 and L3 (also known as R, S and T) respectively. If the meter indicates a counter clockwise movement, swap any two connects between the meter and motor. Then retest. Connect to the MAINS as illustrated. If the meter indicates a clockwise movement, the phases connected to L1, L2 and L3 of the meter are L1, L2 and L3 (also known as R, S and T) respectively. If the meter indicates a counterclockwise movement, swap any two connects between the meter and phases. Then retest. Connect the above mentioned L1, L2 and L3 of a Motor and that of the MAINS respectively should be able to get a clockwise motor movement.
