mV

In AC mode, the frequency may be show dashes if the signal is smaller than the min. sensitivity and trigger level. Please see “Sensitivity and Trigger level” table in the specification section of Frequency.

Measuring Voltage in LoZ Mode

CAUTION

• Do not use the LoZ mode to measure voltages in circuits that could be damaged by this mode’s low impedance.

To eliminate ghost voltages, the meter’s LoZ mode presents a low impedance across the leads to obtain a more accurate measurement. In this mode, meter will automatic measure input signal which is AC or DC and determine range.

To use the LoZ mode, turn the rotary switch to LoZ position

Measuring AC and DC Current

WARNING

• Always use proper terminals, switch position, and range for measurements.
• To avoid possible electric shock or personal injury, never attempt an in-circuit current measurement where the open circuit potential to earth is greater than 1000V.
• Only replace the blown fuse with the proper rating as specified in this manual.

CAUTION

• Replace the fuse as soon as the indicator (FUSE) appears.

To measure current, you must break the circuit under test, then place the meter in series with the circuit.

The ranges of measuring current are 40mA, 400mA, 4A and 10A. AC current is displayed as an rms value. Insert the black lead into the COM terminal. For currents less than 400 mA, insert the red lead into the mA/μA terminal. For currents above 400 mA, insert the red lead into the A terminal.

A/mA

A/mA

In AC mode, the frequency may be show dashes if the signal is smaller than the min. sensitivity and trigger level. Please see “Sensitivity and Trigger level” table in the specification section of Frequency.

Plugging 30A probe to measure up to 30A current.

Measuring Frequency

The meter measures the frequency of a voltage or current signal by counting the number of times the signal crosses a threshold level each second.

This function only can be operated in AC voltage and current measurements. The ranges of measuring frequency are 400Hz, 4kHz, 40kHz and 100kHz.

If a reading shows as 0 Hz or is unstable, the input signal may be below or near the trigger level. The detail of frequency trigger level refer to the electrical specifications.

To use the frequency function, press MODE in the AC measurements, and press Hz key, once activated, will change color, and pressing it again will deactivate the function.

Make High Frequency Rejection Measurement (HFR)

WARNING

• Do not use the High Frequency Rejection (Low Pass Filter) option to verify the presence of hazardous voltages. Voltages greater than what is indicated may be present. First, make a voltage measurement without the filter to detect the possible presence of hazardous voltage. Then select the filter function.

The High Frequency Rejection mode equip a Low Pass Filter in the AC measurements. The cut-off frequency (-3dB point) of Low Pass Filter is 800Hz.

To use the frequency function, press MODE in the AC measurements, and press HFR key, once activated, will change color, and pressing it again will deactivate the function.

Duty Cycle and Pulse width Measurement

The meter measures the positive half-cycle of a square wave, Display the ratio(%) of the positive half-cycle to the entire period or seconds(ms) as the main readings of Duty Cycle and Pulse Width. The secondary reading show the frequency of the waveform at the same time. If a reading shows as 0% , 0ms or is unstable, the input signal may be below or near the trigger level. The detail of frequency trigger level refer to the electrical specifications.

To use Duty cycle function, turn the rotary switch to the DCV position, then press F1 to change measuring mode.

Measuring Resistance

 CAUTION

• To avoid possible damage to the meter or to the equipment under test, disconnect circuit power and discharge all high voltage capacitors before measuring resistance.

The test leads may be add 0.1Ω to 0.2Ω of error to resistance measurements. To test the leads, touch the probe tips together and read the resistance of the leads. For best accuracy, you can use the relative (Δ) mode to automatically subtract this value.

High-resistance (>10MΩ) readings are susceptible to electrical noise. To smooth out most noisy readings, enter the MAX/MIN recording mode; then step to the average (AVG) reading.

Continuity Check

 CAUTION

• To avoid possible damage to the meter or to the equipment under test, disconnect circuit power and discharge all high voltage capacitors before testing continuity.

The continuity check features a buzzer that sounds as long as a circuit is complete. The buzzer allows you to quick continuity checks without watching the display.

When measuring resistance is less than threshold, the buzzer sounds. You can setup the threshold in setup mode.
The continuity threshold is default 30Ω.

To use continuity check, turn the rotary switch to resistance position, then press F1 to change measuring mode.

Testing Diodes

Use the diode test to check diodes, transistors, silicon controlled rectifiers (SCRs), and other semiconductor devices.

For forward-bias readings on any semiconductor component, place the red test lead on the component’s positive terminal and place the black lead on the component’s negative terminal. In a circuit, a good diode should still produce a forward-bias reading of 0.5V to 0.8V.

Measuring Capacitance

 CAUTION

• To avoid possible damage to the meter or to the equipment under test, disconnect circuit power and discharge all high-voltage capacitors before measuring capacitance. Use the dc voltage function to confirm that the capacitor is discharged.
