Measuring AC and DC Voltage
Make dB measurement
This meter have true rms readings, which are accurate
for distorted sine waves and other waveforms (with no dc
o󰀨set) 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.
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 (600Ω)
to calculate a dB value based on 1 milliwatt. A dB measurement
uses a 1 volt reference voltage to compare the present
measurement against. Dene as below :
For best accuracy when measuring the DCmV, touch the
probe tips together and read the DC o󰀨set. If necessary, you
can use the relative (Δ) mode to automatically subtract this
value.

Testing Diodes
CAUTION
• To avoid possible damage to the meter or to the equipment
under test, disconnect circuit power and discharge all
highvoltage capacitors before testing diodes.
Use the diode test to check diodes, transistors, silicon
controlled rectifiers (SCRs), and other semiconductor
devices.
This function tests a semiconductor junction by sending a
current through the junction, then measuring the junction's
voltage drop. A good silicon junction drops between 0.5V
and 0.8V.
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.
For reverse-bias readings on any semiconductor
component, the meter still can measure. In a circuit, a good
diode should still produce a reverse-bias reading of -0.5V to
-0.8V.
The display shows “OL” if the diode is open or short.
To use diode test, turn the rotary switch to resistance
position, then press the function (yellow) button to select
measuring mode.
