4.3 Temperature Correction Factor
Tests have shown that the temperature effect is such that the embedment gauge reading goes
down (compression) as the temperature goes up and the required temperature correction factor is
plus six microstrains per °C.
So, for example, using the GK-502 (displaying mV/V) to take the readings, and a standard eight-
inch-long gauge, where
C
is given in inches/mV/V, the calculation for strain
S
, corrected for
temperature change (T

- T
0
) measured in degrees Centigrade, is:
S = (R

- R

) × C/8 + 6(T

) microstrain
Equation 2 - Stain Calculation with Temperature Correction
Where
C
is given in mm/mv/v the equivalent equation is
S = ((R

- R

) × C/203 + 6(T
