- adjustment locations.
a. Performance Check
(1) Connect calibrator OUTPUT HI and LO to TI INPUT HI and LOW.
(2) Adjust calibrator output for a +1 indication on TI meter. Calibrator will indicate
between .97 and 1.03 V dc, if not, perform b below.
(3) Adjust calibrator output for a -1 indication on TI meter. Calibrator will indicate
between -.97 and -1.03 V dc.
(4) Repeat technique of (2) and (3) above for voltages and TI settings as listed in
table 3; calibrator
within limits specified.
