WV∙Check
If a dc or ac voltage greater than about 4.5V is present across the inputs when the meter is set to R, G, or e, the meter switches automatically to dc or ac voltage mode (V∙Check mode).
WWarning
Repetitive transients on a dc bus will cause V∙Check to select ac volts, even though a hazardous dc voltage may be present. To avoid a misleading display and possible electric shock, manually select the proper volts function for measurements on these circuits.
When V∙Check is activated, the meter has low input impedance (LoZ) ≅2 kΩ. This load can alter the voltages in electronic control circuits. Do not use V∙Check to measure voltage in circuits that could be damaged by a 2 kΩ load.
Hint: V∙Check can be effectively used to eliminate “ghost” voltages.
