a. Performance Check
(1) Move the GAIN VERN, IN/OUT switch to the OUT position and the X1/X.01
switch to the X1 position. Set the GAIN to 10.
(2) Set the calibrator for a 1 V dc output into the TI.
(3) The multimeter will display 9.98 to 10.02 V dc. If not, perform b below.
(4) Move the X1/X.01 switch to the X.01 position.
(5) Set the calibrator for a 10 V dc output into the TI.
(6) The multimeter will display 0.997 to 1.003 V dc. If not, perform b below.
b. Adjustments. None.
a. Performance Check
(2) Set the GAIN switch to the desired gain and the X1/X.01 switch to X1.
(3) Set the multimeter to measure AC voltage.
(4) Adjust the function generator (and if necessary, the gain-vernier control of the
TI) for a 1.000 V rms sine wave of 100 Hz at the TI output.
(5) Set S1 to 2 or short across the resistor. Record the change in the amplifier
=
output voltage as ĆV.
