Surge Testers built to test to the requirements of TIA-968-A, Sec. 4.2.3, Telephone Line Surge, Type B. The surge has an open circuit voltage waveform with a front time of 9uSec and decay time of 720uSec and a short circuit current waveform with a front time of 5uSec and a decay time of 320uSec. The peak output of 1000V / 1500V is set on the front panel meter. The peak short current peak is 25A/37.5A minimum. The polarity is reversible by a front panel switch. Tests L or M are selected by front panel switch as well (not shown). See Actual waveforms in Manual below.

Note:  Options TMM and/or Options 220, 230 0r 240 require Option RE as well.
