WVCheck

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 (VCheck mode).

WWarning

Repetitive transients on a dc bus will cause VCheck 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 VCheck is activated, the meter has low input impedance (LoZ) 2 kΩ. This load can alter the voltages in electronic control circuits. Do not use VCheck to measure voltage in circuits that could be damaged by a 2 kΩ load.

Hint: VCheck can be effectively used to eliminate “ghost” voltages.
