DT‑9960H Multimeter Digital LCD Universal Tester NCV Testing with Overload Protection for Electricity Testing Item Type: Multimeter Model: DT-9960H Material: ABS Battery: 1 x 9V 6F22(battery not included) Purpose: This product can be widely used in residential, industrial factories, tenement, office buildings, home appliance equipment maintenance and testing and other industries Impact Resistance (Drop Test): 2 meters Continuity Test: if the resistance is ≤50Ω, the buzzer will sound, and the test current is <0.35mA Input Impedance: Approximately:> 10M True RMS: AC response The crest factor ≤3 can reach up to 500V at full scale, and the crest factor is reduced to ≤1.5 at 1000V Display: 6000 digit backlit LCD with analog bar graph Over Range: display "OL" Automatic Shutdown: the meter will automatically shutdown after about 15 minutes without operation (can be disabled) Polarity: automatically distinguish the polarity, (-) negative indication Measurement Speed: 3 times per second under normal conditions Fuse: mA, uA range: 800mA/1000V ceramic fast-blow A Range: 10A/1000V ceramic fast fusing Working Temperature: 0℃~50℃ (32℉~122℉) Storage Temperature: -10℃~60℃ (14℉~140℉) Working Humidity: maximum 80% at 31℃ (87℉), and linear drop to 50% at 40℃ (104℉) Storage Temperature: <80%RH Working Altitude: 2000 meters How e: 1. DC voltage measurement 1. Set the function switch to the VDC position. 3. Touch the tip of the black test lead to the negative pole of the circuit; touch the tip of the red test lead to the positive pole of the circuit. 1. Set the function switch to the V/Hz/%/VFD position and indicate "AC" on the display. Alternating current 3. Touch the tip of the black test lead to the negative pole of the circuit; touch the tip of the red test lead to the positive pole of the circuit. 5. Press and hold the MODE button for 2 seconds, "VFD" will be indicated on the display. 6. Read the VFD value on the display. 7. To exit the VFD mode, press and hold the MODE button for 2 seconds. 8. Press the Hz/% button to indicate "Hz". 9. Read the frequency on the display. 10. Press the Hz/% button again to indicate "%". 11. Read the percentage of duty cycle on the display. 1. Set the function switch to the m//Hz/% position. 2. Press the MODE button to indicate "DC" or "AC". 4. Touch the tip of the black test lead to the negative pole of the circuit; touch the tip of the red test lead to the positive pole of the circuit. 6. Press the Hz/% button to indicate "Hz". 7. Read the frequency on the display. 8. Press the Hz/% button again to indicate "%". 9. Read the percentage of duty cycle on the display. 4. Low impedance measurement 1. Set the function switch to LoZ, the LCD display will display the symbols "LoZ" and "AC". 3. Touch the tip of the black test lead to the negative pole of the circuit; touch the tip of the red test lead to the positive pole of the circuit.
