Scope-Test2

P/D 081399

CAUTION! The “Scope-Test2” is a simple piece of test equipment for use by PCC (and X-10)

technicians as an aid in troubleshooting. The user assumes all responsibility for its safe use.

PURPOSE: The function of this device is to reduce the high voltage from an electrical

source (up to 277 volts AC) to approximately one twentieth its original voltage while also

allowing Powerline Control pulses to pass through to be viewed on a standard oscillo-

scope display.

OPERATION: Simply connect the BNC connectors to the inputs of a dual-trace

oscilloscope and adjust the oscilloscope’s controls according to its instruction manual.

Insert the male three prong plug into the electrical outlet from which the PCC signals are

to be tested. The 120kHz pulses generated by standard PCC transmitters and repeaters

will be displayed on the oscilloscope’s display. When properly adjusted, the 60Hz sine

wave will “trigger” the display and cause the 120kHz pulses to be simultaneously

displayed and will show how it is synchronized to that power distribution system. For

more information, please consult the ACT PCC Reference Manual, pages 73 through 75

(these pages are attached).

When used with a user-supplied, properly polarized, spring clip adaptor, the tester can be

used to check for the presence, amplitude and condition of PCC signal on Signal Carrying

Conductor (SCC) lines and on breaker panels.

Caution is urged when using this device

on any breaker panel!

The “Scope-Test2” is not intended for resale and is meant only for ESC use. This unit is

not covered by ACT’s usual 2 year warranty.

XII. BASIC TROUBLESHOOTING: B. TEST EQUIPMENT: NOTE: The examples that follow are representative of a standard, dual trace oscilloscope capable of adding the two inputs together on its display. Simple sweep time and voltage variations will be offered but not complex oscilloscope techniques. It is inappropriate to attempt to give a detailed accounting of oscilloscope use and techniques in this manual.

BASIC TROUBLESHOOTING: B. TEST EQUIPMENT: Low to moderately priced oscilloscopes have limited, but usually sufficient, capabilities. While some units have their highest voltage scale of 5 volts/division (with 10 vertical divisions on the screen) others may have their highest scales as 10 or even 20 volts/division. With an oscilloscope having a 20v/division scale, it is easy to see that the highest voltage that could be displayed would be 200vpp (volts, peak-to-peak).

B. TEST EQUIPMENT: In order to display a very small PCC signal (sometimes well below 25mv) while also showing a 339vpp, 60Hz sine wave, a dual trace oscilloscope is recommended. The first trace, input “A”, is set to display one cycle as described on the previous page, while the second trace, input “B”, is set to display only the bursts of 120kHz.
