(6) Set calibrator for a nominal 19 Ω output. Rotate calibrator knob below EDIT
FIELD pushbutton to adjust calibrator display indication to equal TI indication. If
calibrator err display does not indicate within .632%, perform b below.
(7) Connect calibrator output to TI V/kΩ/S and COMMON. Press kΩ/S function
pushbutton.
(8) Press TI range pushbutton and set calibrator to the nominal resistance outputs
as listed in table 7. At each resistance output, rotate calibrator knob below EDIT FIELD
pushbutton to adjust calibrator display indication to equal TI indication. Calibrator err
display indication will be within limits specified in table 7.

(9) Simultaneously press 200Ω and 2 range pushbuttons to select 2 mS range.
(10) Set calibrator for 1000 Ω nominal output (2 wire comp ON). TI will indicate
between .997 and 1.003.
(11) Simultaneously press 20 and 200 range pushbuttons to select 20 S range.
(12) Set calibrator for 100 kΩnominal output (2 wire comp OFF). TI will indicate
between 9.97 and 10.03.
(13) Simultaneously press 2000 and 20MΩ range pushbuttons to select 200 nS range.
(14) Set calibrator for 10 MΩ nominal output. TI will indicate between 98.0 and 102.0.
b. Adjustments. Press 20 range pushbutton and set calibrator for a nominal 19 ohm
output and adjust R57 for a TI indication equal to value displayed on calibrator to two
decimal places (R).
a. Deenergize and disconnect all equipment.
b. Annotate and affix DA label/form in accordance with TB 750-25.
