1.- OVERVIEW

1.1.- Description

The CPM Current clamp provides functions for the measurement of voltage,
current, resistance, continuity sound alarm, diode test, as well as frequency
measurement.

Three push buttons allow for the selection of functions such as measurement
hold (HOLD), maximum value (MAX) and reset for current measurement DC (DCA
ZERO).
