1. OVERVIEW
The C.A 5275 is a stand-alone portable digital multimeter specially designed to combine all the functions for measurement of
the following electrical quantities in a single instrument:
AC voltage measurement with low input impedance (voltage measurements for electrical and electrical engineering
applications)
AC and/or DC voltage measurement with high input impedance (voltage measurement for electronics)
Frequency
measurement
Resistance measurement
Audible continuity measurement
Measurement and testing of semiconductor junctions
Capacitance
measurement
AC and/or DC current measurement
