(36) Disconnect equipment setup.
(37) Position TI controls as listed in (a) through (d) below:
(a) UPPER FUNCTIONS IN LOWER FUNCTIONS OUT pushbutton to the
OUT position.
(b) CH 1 V pushbutton pressed.
(c) CH 1 VOLTS/DIV switch to 50m.
(d) CH 1 AC GND DC switch to GND.
(38) TI readout will indicate between -.0012 and .0012, if not, perform b (40) and (41)
below.
(39) Set TI AC GND DC switch to DC.
(40) Connect calibrator OUTPUT to TI CH 1 or X & DMM input.
(41) Set calibrator for an output of 400 mV. If TI readout indication is not within
limits specified in first row of table 27, perform b (42) through (48) below.
(42) Repeat technique of (37) (c) and (41) above for calibrator outputs and TI switch
perform b (42) through (48) below.
