10. Resistance Measurement
a. Performance Check
(1) Connect resistance standard (A2) HI terminal to TI LINE terminal and
resistance standard LO terminal to TI GROUND terminal, using leads and adapters (B3,
B4, B1, and B2).
(2) While rotating crank, adjust resistance standard for an indication of 100
kilohms on meter. Resistance standard will indicate between 95 and 105 kilohms.
(3) While rotating crank, adjust resistance standard for an indication of 500
kilohms on meter. Resistance standard will indicate between 450 and 550 kilohms.
