(6) Adjust AMB TEMP (oF) control to 139. If % RPM indicator does not indicate
between 92.6 and 93.6, perform b (4) below.
Figure 7. Standard day check.
(7) Adjust AMB TEMP (oF) control to 59. If % RPM indicator does not indicate
between 99.5 and 100.5, repeat a (3) through (6) above.
(8) Adjust calibrator output to 0.473 mV dc plus millivolt value equivalent to
ambient temperature obtained in table 3.
(9) If TEMP oC indicator does not indicate between 0 and 4, perform b (5) below.
(10) Reverse leads at calibrator output (fig. 7) (BLUE to HI and RED to LO).
(11) Adjust calibrator output to 33.329 mV dc less millivolt value equivalent to
ambient temperature obtained in table 3.
(12) If TEMP oC indicator does not indicate between 796 and 804, perform b (6) below.
(13) Adjust calibrator output to 16.398 mV dc, less millivolt value equivalent to
ambient temperature obtained in table 3.
(14) Adjust audio analyzer for 1.0 V, 63 Hz (15.873 ms) output.
(15) Adjust AMB TEMP (oF) control to 99.
(16) TEMP oC indicator will indicate between 347 and 355, and % RPM indicator
will indicate between 86.3 and 87.3.
