ATS-20B AMMETER & TIMER CALIBRATION METER PANEL CONTROLS

Model ATS-20B is a complete portable current Ammeter, Duration (Shot) time meter with a removable Meter shunt built into a durable abs storage case.Certified to NIST standards to meet or exceed international industrial and military MPI equipment calibration requirements. It will measure AC, FWDC and HWDC current in the Mean Average, True RMS or Peak detection methods in less than 300msec up to 20,000 amperes. It has auto hold for storing last reading indefinitely with automatic reset and update after each measurement or may be operated in manual mode.Duration (Shot) Time is automatic and measures current flow up to 20 seconds.
