WARNING

• When connecting the test leads to the DUT (Device Under Test), connect the common test lead before connecting the live lead. When removing the test leads, remove the test live lead before removing the common test lead.
• The following sections describe how to take measurements with the meter.

Making Basic Measurements
This meter have true rms readings, which are accurate for distorted sine waves and other waveforms (with no de offset) such as square waves, triangle waves, and staircase waves.
The ranges of measuring voltage are 40mV, 400mV, 4V, 40V, 400V and 1000V. To select the mV range, turn the rotary switch to mV position.

For best accuracy when measuring the DCmV, touch the probe tips together and read the DC offset. If necessary, you can use the relative (/\.) mode to automatically subtract this value.

Make dB measurement
The meter is capable of displaying voltage as a dB value, either relative to 1 milliwatt (dBm), a reference voltage of 1 volt (dB).
A dBm measurement must use a reference impedance (6000) to calculate a dB value based on 1 milliwatt. A dB measurement uses a 1 volt reference voltage to compare the present measurement against. Define as below :

To use dB or dBm function, tum the rotary switch to ACV or ACmV position. Then move the blink cursor of menu to dB or dBm position, and press the ENTER button to enter function.
Press the CANCEL button to exit function.

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. The ranges of measuring LoZ voltage are 400V and 1 000V. 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.turn the rotary switch to mV 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 1 0A. 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 terminal. For currents above 400 mA, insert the red lead into the A terminal.
You can press the function (red) button to select current measurement function.

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 1 00kHz.
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 function (red) button to select measurement function.

Make High Frequency Rejection Measurement
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 HFR mode, press the HFR button to equip a low pass filter in the AC measurements.

To use the AC+DC function, turn rotary switch stop in DCV, DCmV or A position, then press function (red) button to select measurement function.

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 ranges of measuring resistance are 4000, 4kO, 40kO, 400k0, 4MO, and 40MO.
The test leads may be add 0.10 to 0.20 of error to resistance measurements. To test the leads, touch the probe lips together and read the resistance of the leads. For best accuracy, you can use the relative (LI.) mode to automatically subtract this value.
High-resistance (>10MO) 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.
