C Using the Battery Option
130 Keysight 53150A/151A/152A Operating Guide
3 Holding one of the batteries so the battery terminals are to your right and the
plus sign at the terminal end is facing away from you, insert the left-hand end
of the battery into the taller end of the battery sled with the far side of the
battery against the far side of the sled. Lower the right end of the battery into
the sled, and push down on the battery until it is down as far as it can go.
Insert the second battery next to the first one in the same manner.
4 When both batteries are fully inserted in the sled, insert the sled into the
battery-chamber opening in the Counter’s back panel (terminal end first).
5 Slide the sled into the battery chamber until you can start the thumb-screws
into the threaded holes in the Counter’s back panel (turn the thumbscrews
clockwise). You may have to push against the back end of the battery sled to
insert it far enough for the thumb screws to contact the back panel.
6 Tighten the two thumb screws on the battery sled until both thumbscrews are
fully hand tight and the back cover of the battery sled is flush against the
Counter’s back panel.
NOTE
The batteries fit snugly into the sled, so it is important to keep them aligned with
the sides of the sled. If you attempt to insert a battery, and it is not parallel with
the sides of the sled, it will bind.
NOTE
The thumbscrews require a considerable amount of turning force, since they
push the battery sled into the Counter and also insert the battery terminals into
the battery connectors as you turn them. To prevent the battery sled or the
terminals from binding or jamming, either turn both thumbscrews
simultaneously, or alternately turn the thumbscrews one-half turn each, until
the battery sled is fully inserted.
