Operating Frequencies: 50 / 60 Hz
Measurement Category: CAT III
Measurement category III is for measurements performed in the building install-
ation. Examples are measurements on distribution boards, circuit breakers, wir-
ing, including cables, bus bars, junction boxes, switches, socket outlets in the
fixed installation, and equipment for industrial use and some other equipment,
for example, stationary motors with permanent connection to the fixed installa-
tion.
The line voltage measurement terminals on the meter are rated for the following
CAT III voltages (these ratings appear on the front label):
