when measured with an appropriate measuring instrument defined in Sec-
tion 11.6.1 of ANSI C39.5.
NOTE: The proper measuring instrument for the measurement of leakage
current consists essentially of a network of a 1500 ohm non-inductive resistor
shunted by a 0.15 microfarad capacitor connected between the terminals of
the measuring instrument. The leakage current is that portion of the current
that flows through the resistor. The Simpson Model 229-Series 2 AC Leak-
age Current Tester meets the ANSI C39.5 requirements for the measurement
of AC leakage current and can be used for this purpose. To measure DC
Leakage current, connect a 1500 ohm non-inductive resistor in series with a
Simpson 0-500 DC microammeter and use this as the measuring instrument.
Multi-function instruments such as the 14510-2 are intended as general pur-
pose measuring instruments for use in relatively low power 120/240 V AC or
dry battery operated circuits such as found in consumer appliances, home
entertainment equipment or general laboratory applications. Some high power
circuits, however, are within its measurement range and present an arcing/
explosion hazard in the event of an unanticipated circuit behavior, a defective
measuring instrument or of an operator error if the operator has not recog-
nized the hazard and observed appropriate personal protective measures.
Such high power circuits that would be within the measuring range of this
Instrument would be found in commercial or industrial equipment operating
from AC and DC supply circuits above 240 V, storage battery banks, or cir-
cuits containing large capacitors. Measurements in such circuits should only
be performed by personnel trained to recognize the hazards and using ap-
propriate safety measures. The Safety Precautions in Section IV are intended
to alert the operator to the more commonly encountered hazards and protec-
tive measures to avoid them. The dangers in high power circuits are serious.
Do not take safety precautions lightly.
NOTE: Any circuit containing voltages exceeding 30 V AC or 60 V DC should
be considered to be a possible shock hazard, and contact with the circuit
should be avoided while the circuit is energized.
