a. Performance Check
(1) Connect 1-turn coil to resistance standard output terminals.
(2) Set TI function switch to Ω (TI displays CAL 7, 6, 5...Cal 1 and a beep is heard).
(3) Set resistance standard for 1 Ω and clamp TI around coil at output terminals. If
TI indication is not within limits specified in first row of table 3, perform b below.
(4) Repeat technique of (3) above for resistance standard values listed in table 3. If
TI indications are not within limits specified in table 3, perform b below.
