Selecting the Grade Sensitivity

The receiver always starts up with the on-grade sensitivity (fine) active.

1. Press the grade-sensitivity button repeatedly to select between fine:

1.5 mm ( 1 / 16 in.) and medium: 3 mm ( 1 / 8 in.) grade sensitivity.

Selecting the Audio Function

The receiver always starts up with the audio mode (loud) active.

1. Press the power/audio button repeatedly to cycle through the audio levels, which include off, soft, and loud.

Note: If the audio function is on, the receiver beeps quickly when the receiver is above the laser beam, slowly when below it, and continuously when centered in the laser beam or on grade.

Using the Receiver with a Laser

1. Press the power/audio button to turn on the receiver.

2. Position the receiver so that its photocell faces the laser.

3. Move the receiver up/down until the LCD and LEDs show an on-grade reading.

Checking Calibration

As with any precision instrument, the calibration needs checking on a regular basis (such as at the beginning of a job, or if the laser has been handled roughly). If the laser is being used at temperatures below freezing, be sure to check calibration under those conditions. The laser is calibrated if the laser plane is within ±2.2 mm (±3/32 in.) of true level at 30 m (100 ft). If the laser has a calibration error, go to the

“Request for Service” section of this manual to get more information.

2. Use the receiver to take an elevation reading for the +Y axis.

5. Calculate the difference between the two elevation readings. If they differ more than 4.4 mm ( 3 /

16

in.), the laser needs calibrating.

Return the laser to an authorized Trimble service center for servicing.

6. To check the X axis, repeat steps 1–5 using the X axis instead of the

Y axis.

Determining the Height of Instrument (HI)

The height of instrument (HI) is the elevation of the laser’s beam.

The HI is determined by adding the grade-rod reading to a benchmark or known elevation.

1. Set up and level the laser.

2. Attach the receiver to a grade rod and turn on the receiver.

3. Place the grade rod on a job-site benchmark (BM) or known elevation.

4. Slide the receiver up/down the grade rod until the LCD shows an on-grade reading.

5. Add the grade-rod reading to the benchmark to determine the height of instrument.

Example: Benchmark elevation = 30.55 m (100.23 ft)

On-grade rod reading = + 1.32 m (4.34 ft)

Height of instrument = 31.87 m (104.57 ft)

6. Use this HI as a reference for all other elevations.
