Working with Sensors

5.1.5 MEASUREMENT MODE

The measurement mode for sensors with ability to zero the reading can switch between

Relative [REL] and Absolute [ABS]. Relative mode means that the sensor reading is

relative to the position where the zeroing occurred. Absolute mode means the sensor

reading is taken from the factory default zero position. For example, for laser sensors,

this is the physical centre of the receiving area.

After executing a ‘zeroing’ using the zero button, the measure mode automatically

becomes Relative. To revert back to Absolute mode, access sensor settings menu,

select measure mode and press enter. ABS is then shown in the square brackets.

Note: On power down, the CB.D2.CAN retains the previously used measurement

mode. It is important before beginning a new job to ensure that the correct

measurement mode is selected.

When system is used in Relative Mode this reading shows the offset from absolute

position.

Select between various units of measurement for different sensor. Different units

available for different sensors are:

Slope Sensor :

1. Percentage [%]

Laser Sensor :

1. Centimeter [cm]

2. Millimeter [mm ]

ZERO

5.2 GRADE TO ZERO OPERATION

The current screen reading for certain models of laser sensor, for GPS sensor and for

mast can be zeroed at any time.

To zero the current reading from the working screen, press the [ZERO] key to zero the

mast connected to CB.D2.CAN

Note:

1. Some sensor model do not support grade to zero.

2. Grade to zero for laser sensors only works if the beam is hitting the sensor.
