In PASS _______ state, the TEST signal indicates HI. _________ The H.V.ON signal remains at LO provided that the voltage between the output terminals remains unchanged, as the signal is synchronized with the DANGER lamp.
  • Page 94 ──────────────────────────────────────────────────── (3) Timing chart at forced termination When the key is pressed to forcibly terminate testing, the unit does not STOP change to either PASS or FAIL status, as test screening is not performed. In this case, the signal becomes HI. In the absence of status indicators (READY/TEST/FAIL/PASS) -- in the SETTING state, when set values are being saved or loaded, or when settings are being made for the optional functions -- all signals become HI.
