FUNCTIONS TRUE RMS Provides a more accurate measure of AC signals that are imperfect waveforms MULTI-TEST Test everything from voltage and frequency, resistance, and continuity along with the ability to test diodes and temperature NON-CONTACT VOLTAGE DETECTION Safely measure AC live voltage without even touching the circuit LCD DISPLAY An illuminated digital LCD display will ensure clear and precise data PRODUCT OVERVIEW... -
Page 4: Button Functions
BUTTON FUNCTIONS MODE AND REL (RELATIVE) BUTTON • Press the MODE button to select AC/DC Voltage, AC/DC Current, Frequency, Ohms, Diode Test, Continuity or Capacitance, Temperature. • Press the REL button for >2 seconds to turn on or off the Relative function. • The Relative function zeros out the reading difference between the actual measurement and the store reference value. NOTE: REL does not work on Frequency, Diode Test, Continuity RANGE BUTTON • When the meter is first turned on, it automatically goes into Auto Ranging. • This automatically selects the best range for the measurements being made and is generally the best mode for most measurements. - Page 5 AC/DC VOLTAGE (FREQUENCY) MEASUREMENT 1. Set the rotary function switch to the V AC/DC position. 2. To select AC or DC voltage, press the MODE button until the AC or DC symbol appears on the LCD display. 3. Insert the black test lead banana plug into the negative COM Input Jack; Insert the red test lead banana plug into the Positive Input Jack. 4. Touch the black test probe tip to the negative side of the circuit; Touch the red test probe tip to the positive side of the circuit. 5. Read the voltage on the LCD display. 6. Press the MODE Button to indicate Hz. 7. Read the frequency in the display.

Page 6: Ac/Dc Current Measurement
AC/DC CURRENT MEASUREMENT 1. Insert the black test lead banana plug into the COM Input Jack. 2. For current measurements up to 10A AC/DC, set the rotary function switch to the 10A position and insert the red test lead into the 10A Input Jack. 3. For current measurements up to 400mA AC/DC, set the rotary function switch to the mA position and insert the red test lead into the Positive Input Jack. -
Page 7: Diode Test
DIODE TEST 1. Set the rotary function switch to the CAP position. 2. Press the MODE button until the symbol appears on the LCD display. 3. Insert the black test lead banana plug into the negative COM Input Jack; Insert the red test lead into the Positive Input Jack. 4. Touch the test lead probes to the diode under test. 5. Forward voltage will indicate 0.4 to 0.7V on the LCD display; Reverse voltage will indicate “OL”; Shorted devices will indicate near 0 and an open device will indicate “OL” in both polarities. CONTINUITY CHECK 1. Set the rotary function switch to the CAP position. -
Page 8: Capacitance Measurement
CAPACITANCE MEASUREMENT 1. Set the rotatory function switch to the CAP position. 2. Press the MODE button until the “nF” symbol appears on the LCD display. 3. Insert the black test lead banana plug into the negative COM Input Jack; Insert the red test lead into the Positive Input Jack. 4. Touch the test leads to the capacitor to be tested, wait until the readings settle before ending the test. 5. Read the capacitance value in the display. TEMPERATURE MEASUREMENT 1. -
Page 9: Non-Contact Ac Voltage Detection
NON-CONTACT AC VOLTAGE DETECTION 1. Set the rotary function switch to the NCV position. 2. Hold the detector close to the AC voltage being tested. 3. If no signal is detected, the LCD will show “EF”, NCV indicator light will not flash and the buzzer will not sound. 4. According to the detected signal strength, LCD displays different horizontal lines. • When the signal is strongest, four horizontal lines with appear on the LCD display. • When the signal is weakest, only one line horizontal line will appear. • Meanwhile, NCV indicator light flashes and the buzzer make a different sound. NOTE: The sensing level varies with the distance between the sensing part and the measured AC power cord. NOTE: The detector is designed with high sensitivity. Static electricity or other sources of energy may randomly trip the sensor. -
