Zero Adjustment Board
Line
Each sensor pin has a line affixed to its base. When
using the zero-adjust feature, align these lines in the
same direction.
As shown in the illustration on the right, select a hole
suited to the distance between terminals on the bat-
tery subject to measurement. Press it in a way sym-
metrical to the central screw on the zero-adjust board.
Insert the sensor pin (line side) into the hole.
Model 9771 (Option)
Let the two points of the pin tip touch the spring
part perpendicularly (be careful not to short the
springs).
When the resistance measurement value is dis-
played as "-----", change the facing direction.
