OPERATION:
High Voltage Warning (HI-V)
The meter beeps and lights an LED when > 30V AC/DC voltage is present
through the test leads of the meter. This enhanced safety feature alerts the user
that dangerous voltage is present across the leads even if the meter is set on an
incorrect function or range.
Notes: This features does not work through the clamp head as the clamp is
