When using the battery test terminals, it is desirable that the battery voltage is measured when The DS3 stimulator employs a total of 11 x 9V (PP3, IEC - 6R61) batteries using one of them operating with a repetitive trigger signal providing a duty cycle greater than 20% or by using to power only the control circuits and ten just for the output circuit. - Page 10 OPERATOR’S MANUAL: DS3 - ISOLATED STIMULATOR WITH CONSTANT CURRENT OUTPUT Issue 3 The DS3 stimulator is manufactured in a two-part plastic box that is held together by four All batteries in the 90V pack must replaced at the same time.
