The SR-98 is a multipurpose, lightweight, field portable test set capable of testing a wide variety of electromechanical, solid-state and microprocessor-based protective relays, small molded case circuit breakers, motor overload relays and similar protective devices.

The SR-98 incorporates a large, easy to read LCD display, which shows AC and DC Amperes, AC and DC Volts, and Time in both Seconds and Cycles. Depending on the type of test selected, other values may be displayed, such as Ohms, Watts, VARS, Phase Angle, Frequency or Power Factor. Metered quantities such as AC Amperes, AC Volts, DC Volts or DC Amperes, and Time are simultaneously displayed on the screen. The read-and-hold metering feature provides a fast and accurate preset of test values.

A relay specific test screen is included in the menu list. The user simply selects the type of relay to be tested and a test screen is provided that displays all necessary functions needed to test that particular type of relay.
