●As Hazardous-Alert: When making resistance measurements in AutoCheck

mode, an unexpected display of voltage readings alerts you that the object under test is

being energized.

●Ghost-voltage buster: Ghost-voltages are unwanted stray signals coupled from

adjacent hard signals, which confuse common multimeter voltage measurements. Our

AutoCheck

mode provides low (ramp-up) input impedance (approx. 1.6kΩ at low

voltage) to drain ghost voltages leaving mainly hard signal values on meter readings. It

is an invaluable feature for precise indication of hard signals, such as distinguishing

between hot and open wires (to ground) in electrical installation applications.

WARNING:

●AutoCheck

mode input impedance increases abruptly from initial 1.6kΩ to a few

hundred kΩ's on high voltage hard signals. "LoZ" displays on the LCD to remind the

users of being in such low impedance mode. Peak initial load current, while probing

directly to 600VAC for example, can be up to 530mA (600V x 1.414 / 1.6kΩ),

decreasing abruptly to approx. 4mA (600V x 1.414 / 210kΩ) within a fraction of a

second. Do not use AutoCheck

input impedance. Instead, use slide-switch function selector

impedance voltage modes (Hi-Z of approx. 5MΩ) to minimize loading for such circuits.
