Shot Timer and Quick Break Tester (MPI Equipment Verification)

This DeltaFlux instrument measures the duration of the magnetising shot and gives a quantitative verification of the quick break function. Shot time and quick break voltage appear on the LCD after each shot. It verifies shot duration on AC, HWDC and FWDC equipment and quick break on single-phase and three-phase FWDC units. The probe sits inside the coil (or in line with a cable wrap) during the shot.

Key features

• Two measurements in one: shot time and quick break
• Numeric result: more accurate than go/no-go LEDs or neon bulbs; actual quick break voltage readout
• Microprocessor control: analyses the quick break pulse waveform
• Traceability: NIST-traceable certificate and 3-year warranty; quick break reference chart on the back
• Why it matters: correct quick break ensures the residual field develops properly and transverse indications are sharp
