(10) Repeat (1) and (3) through (9) above until no further adjustments are required.
10. Dc Current Accuracy
a. Performance Check
(1) Connect calibrator OUTPUT HI to TI mA and calibrator OUTPUT LO to
TI COMMON.
(2) Press mA/A (mA on models 8012A and 8010M) function and AC/DC pushbutton
to DC.
(3) Press TI range pushbutton and set calibrator output for settings listed in table 5.
TI will indicate within limits specified in table 5.

11. Resistance
a. Performance Check
(1) Connect calibrator OUTPUT HI to TI V/k /S (V/k
on model 8010M) and
calibrator OUTPUT LO to TI COMMON.
(2) Press k /S function pushbutton.
(3) Press TI range pushbutton and set calibrator to the nominal resistance outputs
as listed in table 6. At each resistance output, rotate calibrator knob below EDIT FIELD
pushbutton to adjust calibrator display indication to equal TI indication. The calibrator err
display indication will be within limits specified in table 6.
