(12) Operate GA SENS switches on TI while adjusting TI decade switches for null
indications on resistance measuring system. Record value. (Depress BA switch on Model
E3108 to obtain indication.)
(13) Adjust decade resistor for 0-ohms.
(14) Repeat (12) above.
(15) Subtract the value recorded in (14) above from the value recorded in (12) above.
The difference between this value divided by 1,000 and the value recorded in (5) above will
be less than 0.024-ohm.
(16) Turn TI MULTIPLY BY switch to 1/100 and set TI decade switches to 9000.
(17) Adjust decade resistor for 90-ohms.
(18) Operate TI GA SENS switches while adjusting decade switches for null
indication on resistance measuring system. TI decade switches will indicate between 8986
and 9014.
(19) Repeat technique of (16) through (18) above for decade resistor switch settings
and TI MULTIPLY BY switch settings listed in table 6.
