Low impedance input: False voltage generated by large capacitive equipment can be measured.
The input impedance of a low-impedance multimeter is 300kΩ. It can discharge the residual voltage and determine whether the residual voltage exists.
The input impedance of an ordinary multimeter is as high as 10MΩ. Therefore, the residual voltage cannot be identified, resulting in misjudgment or security risks.
There will be residual voltage after powering off large capacitive equipment.
Applied to all electrical equipment, such as reactive power compensation cabinets, and large commercial fluorescent lamps.

Introduce the special features of DMM-8062A
Foreword :
What is Ghost Voltage
The usual digital multimeter is high matching impedance, and the theoretical value is infinite.
When energized and non-energized circuits are close to each other, such as in the same conduit or pipe,
Phantom voltages (stray voltages) commonly known as ghost voltages may occur.
This condition creates a capacitor and allows energization between live wiring and adjacent unused wiring.
Capacitive coupling. (From Internet encyclopedia)
What is low matched impedance measurement?
Master electricians know that voltages often appear when you measure electrical installations, even if you know the wires
All are not powered.
This is caused by stray capacitance or ghost voltages and capacitance between wires as mentioned above. due to very high
The impedance of the input meter,
This stray voltage has nowhere to go and is causing an incorrect reading on the meter. This is because in the highly matched impedance capacitance
It is easy to absorb environmental noise so that many multimeters will see unstable voltage jumps unstably in mV under the DC voltage gear.
This digital multimeter DMM-8062a adds a Noncontact voltage detector and low matching impedance
Check out and make sure there is a low impedance across the meter's input terminals.
