6 DISTANCE MEASUREMENT

6-1 Target Setting

The target mode and its Constant of current setting are shown at the left of the

battery mark. For example in case of each Constant 0,

Reflector sheet; S 0, Reflectorless(Non-Prism); N 0, Prism; P 0

Pressing [F2][TARGET] changes the target

mode.

●The target mode is changed sequentially as follows.

Reflector sheet - Prism - Reflectorless (reflectorless models),Reflector sheet -

Prism (standerd models).

●The selected target mode is stored in the memory even if the power is turned

off. So, next time you can use the same mode after turning on.

●The target Constant differs according to the selected target mode.

So, confirm the target mode and its Constant shown at the top screen after

changing the target.

1. (Distance measurement by Reflectorless (Non-Prism) mode)

●The measurement range is determined by the white side of the Kodak Gray

Card facing the instrument and by its surrounding brightness.

There is a possibility that the range may vary when the target does not satisfy

the conditions above at survey work.

●Pay attention to the following in case of distance measurement by Reflectorless.

In case of resulting in low accuracy, perform the distance measurement by

Reflector sheet or Prism.

●The Reflectorless “Long Range mode”can be accessed by the 007 CODE

number 521 [REF.LESS RANGE].The measurement range of this mode is

150m and the Laser class is IIIa.This mode can be performed by selecting

the “LONG”at 1.REF.LESS RANGE.

●The CODE number 521 [REF.LESS RANGE] shows 1.REF.LESS RANGE

(NORMAL/LONG) ,2.LONG RANGE MES(ON/OFF).and 3.LONG RANGE

SETUP(EACH TIME/PERMANENT).

●The WARNING (Laser Power) screen is displayed when Range LONG and

Message ON are selected, and then F1-MEAS key is pressed. F1-MEAS, F3-

NORMAL and F5-LONG are viewed.

●Pressing [MEAS] one time selects “Second MEAS setting”and twice selects

“QUIT”. And then, Normal or Long measurement is selected by pressing F3 or

F5.
