(7) Set SW-6 switch to RANGE.
(8) Adjust C control for 0 indication on GALVO-1. If TI C dial does not indicate
0 1, perform b (1) through (13) below.
(9) Set SW-6 switch to MECH. ZERO.
(10) Set calibrator to standby and reverse connections at calibrator input.
(11) Adjust calibrator output to 48.462 mV less value recorded in (6) above.
(12) Adjust C control until dial indicates 1190.
(13) Set SW-6 switch to RANGE.
(14) Adjust C control until GALVO-1 indicates 0.
If C dial does not indicate
between 1189 and 1191, perform b 1) through (13) below.
(15) Set SW-6 switch to MECH. ZERO.
(16) Repeat technique of (11) through (14) above, using values listed in table 4. TI C
dial will indicate within limits specified.
