4 STANDARD MEASUREMENT MODE

4.2.6 Stake Out (S-O)

The stake out distance is the difference between the measured distance and the preset distance.

Display value = Measured distance -Standard (Preset) distance

The value on the display is the distance in which the rod person must move toward or away from the instrument. A minus (-) sign appearing before the stake out distance indicates that the rod person would move away from the instrument to reach the stake out distance. If the stake out distance is displayed with no sign, indicating positive (+), the rod person toward the instrument to reach the stake out distance.

lStake out operation can be accomplished in any distance measuring mode, horizontal distance (HD), relative elevation (VD), or slope distance (SD).
