(13) Determine average of deviations recorded in (14) above. If average deviation is
not within 0.05 degree, perform b below.
(14) Repeat technique of (9) through (13) above for each TI model at temperatures
listed in table 5. If average allowable deviations are not within limits specified, perform b
below.

1This
thermometer set may be calibrated to the same accuracy as thermometer set 7910479 using same technique.
This set is graduated to the Fahrenheit scale. Therefore, conversion to the equivalent Celsius value of this table is
necessary. The temperature conversion formulas below may be used.
F = ( C X 1.8) + 32
C = ( F - 32) 1.8
2Procedure limitation. ASTM 70F is beyond the range of temperature bath.
(15) If ZERO point correction recorded in 8 a (4) above has changed from initial
calibration correction chart, apply ZERO point correction to each scale point listed on
correction chart.
