Rod Eye 180, Automatic Field Calibration - Rugby 820/840
Automatic Field Calibration - Rugby 820/840
This procedure is unique to the Rugby lasers and uses the digital readout of the
Rod Eye 180 receiver to measure, then adjust the plane of each axis.
Objective: To rotate the laser to all four axes, then allow the receiver to adjust the
beam automatically.
Step
Description
1.
Pair the receiver to the laser (if not already done). Refer to for more infor-
mation.
2.
Mount the laser on a flat, level surface or tripod.
3.
Turn on the laser and align the X-axis toward the receiver position.
4.
Mount the receiver to a fixed position (e.g., a stationary grade rod) approx-
imately 30 meters (100 ft) from the laser.
5.
Turn on the receiver and position the height of the receiver near or at the
on-grade position. It is not necessary to be exact.
6.
Turn off the receiver.
7.
Turn on the receiver in CAL mode by pressing both the power and Laser man
button for five seconds.
8.
The display will show CAL.

9.
Return to the laser and note the colour and activity of the X and Y LEDs.
• With each rotation it may take up to 10 seconds for the calibration process to iden-
tify the axis being checked, i.e. before the LED starts to blink red.
• Each step of the process is very exact and may take 1 minute to complete before
the LED turns to green.
• It is important to note the colour and blink sequence to know the status of each
axis in the process.
• It is not necessary to follow the steps in the exact order, but different rotation
sequences will result in different LED indications.
• Increasing the distance beyond 30 meters (100 ft) between the laser and receiver
will not increase the accuracy of the calibration process.
