Input voltage: 120V AC or 240V AC.
Square shape panel 96 x 96mm.
360° indication.
PC window, ABS resin frame, PC case.

Operation Principle
1) A synchroscope indicates the synchronization point (scale center) when the frequencies and the phases at a generator side and a bus line side are matched.
2) If the frequencies of both side are equal, the position at which the needle is stationary indicates the phase difference between the two.
3) When the generator side (starting side) frequency is fg and the bus line side (operating side) frequency is fb, the direction of rotation of the needle is as follows:
When fg = fb The needle is stopped.
When fg > fb The needle rotates in the FAST direction.
When fg < fb The needle rotates in the SLOW direction.

Nominal Input Voltage: 120V AC for HLS-96A SYNC (120V) | 240V AC for HLS-96A SYNC (240V).
Frequency Range: 50Hz or 60Hz.
Scale: SLOW / FAST.
Indication: Moring pointer.
Angle of rotation: 360°.
