Megger SST9203 Solid-State Digital Timer

Overview

The Megger SST9203 is a precise solid-state digital timer designed specifically to measure the operating time of solid-state and electromechanical relays, circuit breakers, contactors and similar switching devices. Its flexible triggering and high resolution make it a versatile timing instrument for utility field crews, test shops and laboratories.

Two independent start and stop gate circuits can each be triggered by a dry contact opening or closing, or by the application or removal of an AC/DC potential (5–300 V), so the SST9203 adapts to virtually any device under test. A clear six-digit LED display shows results in seconds or cycles with resolution to 0.1 ms and high accuracy, while a built-in rechargeable battery gives around six hours of portable operation.
