5.3 Measuring DC and AC Amps
5.3.1 Refer to Section 3.0, Preparation For Use, and Section 4.0,
General Operation, before attempting any measurements.
5.3.2 Select the desired AC or DC Amps function by rotating the
Range Switch to the desired function.
If measuring AC Amps with a Test Set with Cab Filters, set the Sig-
nal Select Switch to AP +/- to measure all AC current present. If
only cab signals are of interest, then set the Signal Select switch to
the appropriate frequency. The Test Set will measure only that sig-
nal. If using a Test Set without Cab Filters, all AC current present
will be measured.
For DC Amps, if it is desired to measure transmit and receive cur-
rents, place the Signal Select switch in the AP +/- position (Test
Sets with Cab Filters) or the +/- (Test Sets without Cab Filters) posi-
tion. The peak level and timing parameters of the highest amplitude
signal are now automatically measured.
To select a particular polarity (transmit or receive) to measure, sim-
ply change the Signal Select switch to the + or the -position. That
signal will be captured. If the signal is of the opposite polarity (e.g. a
positive signal when the switch is set to -) the pointer will deflect
down scale. On Test Sets with Cab Filters, the + and - positions of
the Signal Select switch are also labeled with the Cab frequencies
applicable to that Test Set.
5.3.3 Attach the test leads to the Test Set. The red lead is con-
nected to the 1.5 Amp Jack to measure 1.5 Amps AC or DC. It is
connected to the 6 Amp Jack to measure 6 Amps AC or DC, and it
is connected to the 30 Amp Jack to measure 30 Amps AC or DC.
