A four-position switch located under the am-
meter. The first three positions select full
scale indications of 3, 10, and 30 A RMS. The
fourth selects a centre-zero scale with
±
10 A
DC full scale deflection and is used when
centring the moving element or to apply a
static force to the test specimen.
A BNC socket provides an oscilloscope display
of current waveform, including the DC com-
ponent. The output is short-circuit protected
by a 1
oon
internal series resistor. Sensitivity
is 20 mV /A. A phase inversion occurs at this
socket.
