If this instrument is damaged or a part is missing, please contact your seller immediately. Failure to observe the instructions or precautions of use may impair the protection provided by the instrument.

To avoid exposure to laser radiation, injury, or damage to this instrument, and make sure that you are using the rangefinder safety, observe the safety tips given below:

• Do not aim the laser sight at anyone's eyes,
• Do not place the rangefinder on or near objects of which the temperature is >65^ / 150^ ,
• If the rangefinder is exposed to large variations of ambient temperature, wait for the temperature to stabilize, then wait 30 minutes before resuming the measurement, to attain the specified accuracy,
• Let any condensation that might form on the lens of the measurement orifice of the rangefinder evaporate before resuming the measurement,
• Do not expose the rangefinder to strong electric or magnetic fields, which can cause measurement errors (avoid, for example, induction heaters, arc welding equipment, etc.),
• Comply with the climatic environmental conditions (see § 4),
• Keep the lens perfectly clean.

1.3.GENERAL

The CA 1730 LASER rangefinder is a non-contact distance measurement instrument that can also calculate areas and volumes. It works by emitting a brief pulse that is reflected from the target and received by a photodetector. The distance between the rangefinder and the target can be computed from the elapsed time between the emission and reception of the signal.

3. CONFIGURATION

3.1.SWITCHING ON / OFF

MEAS

To switch the instrument on (by a long press), activate the LASER, and make a measurement.

CLR

A long press on this key turns the instrument off. The instrument switches itself off automatically after 3 minutes of inactivity.

3.2.EFFACEMENT

CLR

The last action is cancelled or the display of the value is cleared.

3.3.REFERENCE LEVEL

Press the key to toggle the reference point between the front, the back, or the ruler of the instrument. An audible beep indicates that the reference has been changed.

As default, the reference level is on the back of the instrument. When the instrument is switched on, the reference is automatically reset to the default value (back of the instrument).

3.4. LIGHTING OF THE DISPLAY UNIT

Press the key to switch the backlighting on or off.

3.5. CHANGING THE UNITS

A long press on the in, ft.+in).

key changes the unit of measurement (m, ft.

4. MEASUREMENT

Never aim the LASER sight at anyone's eyes.

4.1.SIMPLE DISTANCE MEASUREMENT

During a simple distance measurement, the symbol is displayed.

1: Press MEAS once to activate the LASER.
2: Press MEAS again to trigger the measurement.

The value measured is displayed immediately.

4.2.CONTINUOUS MEASUREMENT (MINIMUM / MAXIMUM)

The continuous (tracking) measurement mode is used to go to a specified distance, for example as indicated by a blueprint. In this mode, the rangefinder can be moved with respect to the target; the measurement is displayed in the third row. The minimum and maximum values are automatically indicated in the first and second rows.

1: Press the MAX/MIN key to activate continuous measurement.
2: Pressing MEAS or stops the function.

4.3.MEASUREMENT OF AREA

1: Press the key, the symbol is displayed.
2: Press twice to make the first measurement, for example the length.
3: Press MEAS again to make the second measurement, for example the width.

The calculated area is indicated in the last row. The individual measurements are recalled in rows 1 and 2, and the perimeter is displayed in row 3.

4.4.MEASUREMENT OF VOLUME

4.5.INDIRECT MEASUREMENT - TWO-POINT PYTHAGOREAN

The indirect measurement is used to determine a distance using auxiliary measurements. For example, a height can be measured by measuring two other distances.

The target points must be on the same line. The orientation of the LASER during the measurement of the second distance must be perpendicular to the line.

7. MAINTENANCE

Except for the batteries, the instrument contains no parts that can be replaced by personnel who have not been specially trained and accredited. The manufacturer cannot be held liable for any accident that occurs following a repair done by anyone other than its customer service department or an approved repairer.

7.1. OPERATING PROBLEMS

Measurement errors may occur on semi-transparent materials, glass, Plexiglas, or similar materials. In such cases applying a sheet of paper will facilitate the measurement. Varnished surfaces can deflect the LASER beam and also lead to measurement errors. The measurement time may be increases in the case of non-reflecting surfaces.

Some errors are reported in the form of codes. The table below links the error codes to possible solutions.

Code Cause Corrective measure
204 Error of calculation Repeat the procedure
208 Too much current Contact your dealer
220 Batteries low Replace them
252 Temperature too high		Place the instrument in a temperature location
253 Temperature too low		Place the instrument in a temperature location
255	Signal received too weak; the measurement time is too long	Use a target plate to improve the reflection
256	Signal received too strong	The target point reflects too much; use a target that reflects less
261 Measurement out range Target outside measurement range
500 Hardware error		Switch the instrument on and several times. If the problem persists, contact your dealer

7.2.CLEANING THE MEASUREMENT LENS

Dust gently with a soft, moist cloth or a blower.

Do not use a solvent.

7.3.CLEANING THE HOUSING

Clean the housing using a cloth moistened with soapy water. Rinse with a damp cloth.
