• Check the test leads for continuity. Replace damaged test leads before using the Meter. • Have the Meter serviced only by qualified service personnel. • Use extreme caution when working around bare conductors or bus bars. Contact with the conductor could result in electric shock. • Do not hold the Meter anywhere beyond the tactile barrier. • When measuring current, center the conductor in the clamp.
1 1.5 V AA batteries (installed) 1 Users manual 1 Carrying case If any of these items are damaged or missing, return the complete package to the place of purchase for an exchange. MEASUREMENTS � Warning To avoid possible electric shock or personal injury: • When measuring current, center the conductor in the clamp. • When making current measurements, disconnect the test leads from the Meter. • Keep fingers behind Tactile Barrier. • Use the proper function and range for measurements.
REC / PEAK-RMS Press REC button to activate maximum, minimum and average reading memory mode ( MAX MIN AVG is displayed). The meter beeps when MAX and MIN reading is updated during measurement. Press REC button again to read the MAX, MIN and AVG reading in sequence. Press REC button > one second to exit MAX/MIN/AVG reading memory mode. Press REC / PEAK-RMS button > one second to enter is displayed) to capture PEAK-RMS mode ( inrush current or voltage RMS values (80 ms).
Note: • AC V (and hence DC+AC V and Hz) function is equipped with digital low-pass filter, and is capable of dealing with VFD (Variable Frequency Drives) signals. It also improves AC V reading stability in noisy electrical environments. Voltage Detection (NCV) Non-Contact Voltage Detection: 1. Turn the rotary switch to NCV (EF). Press SELECT button to toggle NCV (EF) mode (“EF” is displayed). 2.
Measuring AC and DC Current � Warning To avoid electrical shock and injury: • Remove Test Leads before making current measurements. • Do not hold the Meter anywhere beyond the tactile barrier. • Do not use the Meter to measure currents above the maximum rated frequency (400Hz). Circulating currents may cause the magnetic circuits of the Jaws reach hazardous excessive temperatures. To measure AC or DC current: 1. Turn the rotary function switch to . 2.
� Caution During current measurement keep the jaws away from other currentcarrying devices such as transformers, motors or energized wires, as they may negatively influence accuracy of the measurement. Precise Low-Current Measurement � Warning To avoid electrical shock and injury: • Remove Test Leads before making current measurements. • Do not hold the Meter anywhere beyond the tactile barrier. • Do not use the Meter to measure currents above the maximum rated frequency (400Hz).
� Caution During current measurement keep the jaws away from other currentcarrying devices such as transformers, motors or energized wires, as they may negatively influence accuracy of the measurement. Microamps μA Measurement The μA DC ( ) function on the Meter is primarily for HVAC flame sensor testing. To test a heating system flame sensor: 1. Turn the heating unit off and locate the wire between the gas-burner controller and the flame sensor. 2. Disconnect one of the flame sensor wires. 3.
Measuring Resistance, Continuity and Diode � Warning • To avoid false readings that can lead to electrical shock and injury, deenergize the circuit before taking the measurement. • To avoid electrical shock when testing resistance/continuity/diode in a circuit, make sure the power to the circuit is turned off and all capacitors are discharged. Use DC voltage function to check the capacitors are discharged. 1. Connect the black test lead to the COM terminal and the red test lead to the Ω terminal. 2.
Measuring Capacitance and Temperature � Warning To avoid electrical shock and injury: • When testing capacitor in a circuit, make sure the power to the circuit is turned off and all capacitors are discharged. • When measuring temperature, DO NOT apply the temperature probe to any live conductive parts. Capacitance 1. Turn off circuit power, then disconnect and discharge the capacitor before measuring capacitance. 2. Connect the black test lead to the COM terminal and the red test lead terminal to the 3.
Measuring & 3-Phase Rotation Measurement is made through the Meter’s terminals L1/L2/L3. Phase Rotation directions are indicated as symbolic (LCD segments) movements on the display. Default mode at . Press SELECT button to toggle between and modes. : Hi-sensitivity mode for checking phase rotation of Motors detects relatively low signal outputs generated spinning a motor shaft,. : Normal-sensitivity mode for identifying phase sequence of 3-phase MAINS supply.
Normal mode for the MAINS circuit: Connect the test lead L1/L2/L3 to the 3-phase mains circuit by using probes and/or alligator clips. 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 counter-clockwise movement, swap any two connects between the meter and phases. Then retest.
