CAUTION
When making voltage measurements on the PMT08A board, be sure to touch the
terminals of the board by the tester probes with the high-voltage switch in its OFF
position, and then turn ON the high-voltage switch. It is dangerous if the high-voltage
switch is turned ON, because high voltage is applied to the PMT08A board.
