a. Remove protective cover as needed to make adjustments.
Replace cover after
completing the adjustments.
b. Connect TI to a 115 V ac source.
c. Press TI POWER pushbutton to in position (on) and allow at least 1 hour for warm-up.
d. Position TI controls as listed in (1) through (3) below:
(1) AC DC to DC (out position).
(2) Function to V (in position).
(3) Range to 200m (in position).
a. Performance Check
(1) Connect calibrator OUTPUT HI to TI INPUT HI and calibrator OUTPUT LO
to TI INPUT LO.
(2) Set calibrator for an output of 0 mV.
(3) Press TI REL pushbutton and verify TI displays 000.000 mV 1 count.
NOTE
Leave TI in REL mode for entire DC voltage check.
(4) Change calibrator output to 190 mV.
If TI does not indicate within limits
specified in first row of table 3, perform b below.
(5) Press TI 2 range pushbutton (in position).
(6) Repeat technique of (4) and (5) above for remaining calibrator outputs and TI
range settings in table 3. If TI does not indicate within limits specified in table 3, perform
b below.
