The SLM3505 was designed to provide a single instrument solution for the Electric Utility System Protection Engineer and
Relay/Communications Technician responsible for the alignment and maintenance of Power Line Carrier, Audio Tone and FSK
Communications Systems. This multifunction instrument replaces all 4 existing Power Line Carrier Instruments in one for a fraction
of the cost, all in a compact lightweight package.
Featured Application Highlights
LINE TRAP TESTING
LINE TUNER TESTING
The SLM3505’s Impedance Analyzer provides an impedance
versus frequency plot directly on the display. A technician can
therefore view a curve representing the resonant frequency
and adjust a trap and tuning pack while viewing the changes
in a real time environment, without having to adjust the meter.
Since the SLM3505 is a true LCR Meter with the ability to
zero out cable impedance, test lead length and separation is
no longer a concern. Now the technician can attach long
leads to a mounted trap and perform testing while still on the
ground, by simply zeroing the capacitance in the leads.
The SLM3505 provides a single instrument solution for
adjusting a Tuner’s Series inductor and Impedance Matching
transformer for minimum reflected power. The 3505
achieves this either with a conventional directional coupler
technique or by an innovative impedance comparison
technique that achieves the same measurement results
without the need for any additional hardware. Using either
technique in VSWR mode, a single screen displays the
frequency under test, the forward power level, the reflected
power level and the % reflected power.
