Model 150-2 Amp-Clamp ....................................................................... 00541
1.13.1 Amp-Clamp
Model
150-2
The Simpson Amp-Clamp Model 150-2 allows AC current measurements without
breaking the circuit under test. The Amp-Clamp works in effect as a transformer
containing a split core for accommodating the conductor which carries the current
being measured. The current-carrying conductor becomes the transformer pri-
mary and a coil in the Amp-Clamp serves as the secondary winding. The Amp-
Clamp output voltage is proportional to the current measured and can be applied
to the 260-8 as an AC voltage.
The Amp-Clamp has a range selector with six positions. Any of the following
current ranges can be used with the 260-8: 5, 10, 25, 50, 100 or 250 amperes.
NOTE
: Instructions are furnished with each Amp-Clamp.
