ABSTRACT:
A method and apparatus for calibrating a CRT arc counter or other current triggered device having a bifilar wound core and circuitry for causing a predetermined current pulse train to run through said core. Each pulse in the current pulse train creates an electromagnetic field around the core. A probe of the arc counter or other current triggered device is positioned within the electromagnetic field of the core so as to detect it. The calibration apparatus is provided with a switch which can attenuate the current pulses through the core by a predetermined amount. The sensitivity of the device under calibration is adjusted so as to be triggered by the unattenuated pulses and not triggered by the attenuated pulses.
