## Temperature Correction

##### To be added or subracted

$c_t$ = temperature correction

$C$ = Coefficient of thermal expansion

$T_o$ = observed temperature

$T_s$ = standard temperature

$L$ = nominal length

## Tension/Pull Correction

##### To be added or subracted

$c_p$ = tension/pull correction

$P_o$ = observed tension/pull

$P_s$ = standard tension/pull

$L$ = nominal length

$A$ = cross-sectional area of tape

$E$ = modulus of elasticity of tape

## Sag Correction

##### To be subracted

$c_s$ = sag correction

$w$ = weight of tape in plf. or kg.m.

$L$ = unsupported length of tape

$P$ = actual pull/tension applied

## Slope Correction

##### To be subracted

$c_{slope}$ = slope correction

$h$ = difference in elevation at the end of the tape

$S$ = inclined distance

$H$ = corrected distance
