b. Adjustments.
(1) Release HI LO pushbutton (HI) and set calibrator for a nominal 19 kΩ output.
(2) Adjust HI Ω R1426 (fig. 2) for a TI indication equal to calibrator's displayed
value for 19 kΩ (R).
(3) Press HI LO pushbutton (LO); then adjust LO Ω R1412 (fig. 2) for a TI
indication equal to calibrator's displayed value for 19 kΩ (R).
21. Final Procedure
a. Deenergize and disconnect all equipment.
