9. Meter Range
a. Performance Check
(1) Connect calibrator to TI input terminals.
(2) Adjust calibrator frequency for 1 kHz and output for a full-scale (50) indication
on TI. If calibrator does not indicate between 201.65 and 246.47 V (209.62 and 236.38 for
TS-585A/U, perform b below.
(3) Repeat technique of (2) above for TI switch settings listed in table 4. If
calibrator does not indicate within limits specified, and b was not performed in (2) above,
perform b below.
