抄録

A chaged volmeter circuit in codenser discharge type of X-ray apparatus consists of two condensers, earth and a charged voltmeter. The two condensers are joined to series, earth to the middle point, a condeser of a pair to a charged veltmeter through high resistance. This apparatus has demerit. There are unbalance in condenser voltage when radiography has been done after, charging and leaving as it was, indicator of a charged voltmeter descended naturally, or when radiographed by a triade controlled shutting method. And it causes error in indicated value. It is evident experimentally that this error has a large effecton film concentration. For dissolving this error, resistance, equal to that of a charged voltmeter, should be joined to the other condenser.
