AUTOMATIC TRACKING FUNCTION
(Available for vertical laser lines only)
The automatic tracking function is only effective together with receiver FR 57-TR.
For the axis-alignment:
.
Position the laser over the ground point.
.
Align the on-grade-mark of receiver FR 57-TR at the target point.
.
Activate receiver FR 57-TR.
.
The closest vertical laser line moves to the on-grade-position of the receiver automatically.
The receiver FR 57-TR can also be used as:
.
normal receiver detecting the horizontal / vertical laser lines
.
remote control to operate the horizontal movement manually
The receiver FR 57-TR receives the laser line signal from the instrument and sends out an infrared
remote command to the instrument base. The base rotates until the laser line is exactly centered to
the on-grade position of the receiver. (Range: 50 m).
Power on the receiver by pressing button 2.
A long beep will sound and the LEDs on the left side of the receiving window will flash one after the
other (top = red, middle = green, bottom = yellow).
Now the receiver is in receiving mode and the sound is in low volume.
Press button 2 again to power off the receiver. Three short beeps will sound.
Press button 1 long to power on or off the signal tone.
Press once long for sound ON
(Confirmation: one beep)
Press two times long for sound OFF
(Confirmation: two beeps)
Press button 1 short to select the SHORT distance or LONG distance receiving mode.
Press once short for LONG
(Confirmation: green LED indication)
Press two times short for SHORT
(Confirmation: LED off)
DISTANCE SHORT/LONG
With the function DISTANCE SHORT/LONG the radius of the tracking function will be determined;
i. e. by selecting the tracking radius of the instrument interactions of several instruments on the same
contruction sites will be avoided.
Tracking distance SHORT = 8 - 15 m
Tracking distance LONG = 50 m
