Specifications - AEMC 725 User Manual

Beyond the absolute product ruggedness and overall design qualities —
the Model 725 is built with GE Lexan
dards — the instrument features a high level of safety. The Model 725
meets or exceeds UL 1244 safety standards as well as IEC 1010-1 Category
III for 600 V ratings (UL
The Model 725 is comfortable to hold, compact and easy to maneuver in
crowded breaker panels. Yet the hooked jaw design facilitates clamping
and accommodates two 500 MCM conductors.
The high sensitivity Model 725 allows low input levels (300 mA and 50
mV), permitting power quality measurements on low power or idling
equipment — an advantage not common to many instruments.

ELECTRICAL SPECIFICATIONS
Reference Conditions:
Accuracies are provided under the following reference conditions: Temperature
23°C ± 3K, 45% to 75% RH; battery voltage 6 V ± 0.1 V; conductor centered in
the probe jaws; DC magnetic field: earth's field (<40 A/m); no external AC mag-
netic field; no external electrical field; sine wave 45 to 65 Hz; signal present <30s
above 50 A. In THD and DF, the basic accuracy is provided for a square wave and
a triangular wave with 50% duty cycle at 50 or 60 Hz. Particular reference condi-
tions: In DC amperes, the AC component <0.1% of total signal, zeroed core rema-
nence and signal magnitude >5 A; in AC amperes the signal is a sine wave of mag-
nitude >5 A.
R refers to Reading and ct(s) to count(s). Counts may also be referred to as the
least significant digits (LSD).
