VCHEK AND HOW TO USE IT
i is a subset of the continuity/ohms function. In i, the meter is designed to
automatically display an ac or dc voltage when the meter detects a voltage greater in
magnitude than about 4.5 V and the meter is not in the manual range mode. THIS
WILL NOT HARM THE METER. i is always enabled (and k is displayed) when
the meter is in the continuity/ohms function unless the meter is in one of the following:
• The manual range mode (i.e., Z is displayed)
• The MIN MAX mode (i.e., j is displayed)
• The capacitance function (i.e., µF is displayed)
WWarning
Repetitive transients on a dc bus will cause i 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.
In i, the meter has a low input impedance (~2 ke). When a voltage is displayed,
LoZ is also displayed to remind you of this, and the beeper momentarily sounds a
i Alert™. To disable the i Alert in the ohms function, press and hold down
[g] while turning the meter on.
