(5) Set calibrator to the first Displayed Output value in table A-4, output to OPR.
(6) Allow time for multimeter indication to stabilize then record the value in
"multimeter indication" column of table A-4.
(7) Calculate the true applied calibrator current by dividing the multimeter
indication by the test report value (from table A-1) of the resistance standard. Record this
value in the calibrator True Applied column in table A-4.
(8) Repeat technique of (4) through (7) above for remaining rows in table A-4. Use
calibrator +/- key to change polarity.
(9) Set the calibrator output to minimum and disconnect equipment set-up.
(10) Use values from table A-4 to complete the tables in paragraphs 12 a and 15 e.
