• Specially designed to test whether the coil resistance, contact continuity, and operational performance of various relays for automotive, industrial, and power protection meet the standards.
• It can accurately measure the pull in voltage and release voltage, and determine whether the relay coil can operate normally within the specified voltage range.
• Support cyclic on-off testing of relay contacts to effectively detect poor contact or intermittent faults.
• Equipped with contact resistance or contact voltage drop testing function to ensure reliable conduction of the relay under load conditions.
• Can detect the action time and release time of the relay, and evaluate whether its response speed meets the design requirements.
• Some models can test the reverse peak voltage and the direction of the coil connected to the diode to prevent damage to the circuit when the inductive load is powered off.
