The Crompton Instruments AC synchroscope measures and displays the frequency difference of two power sources. Monitoring the display allows the user to connect two synchronized AC power systems together. This can help prevent the potential damage caused by connecting two unsynchronized power sources. The 4.50" meter complies with ANSI C39.1 specifications.

TE Connectivity’s (TE) Crompton Instruments ANSI Rotary Synchroscopes measure and display the frequency difference between two power sources. Monitoring the display allows the user to connect two synchronized power systems together.
The rotary design gives real-time feedback on the synchronization state, ensuring a safe and reliable synchronization. When the synchronization state is achieved, the indicator stays
in the synchronizing position. The ANSI Rotary Synchroscope complies with UL Approved E203000 and ANSI C39.1 standards.
