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.

INSTALLATION The following contains instructions for installation and shipping of the 150-2. Included are unpacking and inspection procedures, warranty, shipping and care. Unpacking And Inspection Examine the shipping carton for signs of damage before unpacking. If un- damaged unpack the instrument and inspect it for possible damage. Check that all furnished items and accessories are included (Table 1-2).
The current range used depends upon the dial scale available on the AC instrument used with the 150-2. The range selector switch is operated by a large diameter recessed thumbwheel. It enables one hand operation for holding the 150-2, clamp- ing it around the test current conductor, and switch- ing the ranges at the same time.
Set the indicating instrument to 2.5, or 3V AC range, whichever of these two ranges and scales is available on the instrument being used. Set the current range selector switch on the 150-2 to a range which cov- ers the probable current to be measured. While the 150-2 circuit con-...
To read a current of about 1.5 amperes with the 150-2 set at the 0-5 ampere range, loop the con- ductor through the jaws of the 150-2 as indicated in Figure 5-1, A. The sensi- tivity of the probe is then multiplied by two, changing the 0-5 ampere scale, in effect, to a 0-2.5 ampere scale.

For instance, by looping ten turns of the conductor through the jaws of the 150-2, the 0-5 ampere scale is changed, in effect, to a 0-500 mA scale. Currents as low as 50 milliamperes can then be measured with reasonable accuracy.
