Important Information

This guide provides instructions for the Certa 2-in-1 40m Laser and Tape Measure. Ensure the device is charged before first use. The device allows for both physical tape measurements and laser distance measurements, including area, volume, and Pythagorean calculations.

Components Overview

The device consists of the following main parts:

Tape measure
Clip
USB Type-C charging cable
User guide

The control panel features a display, a laser emitter, and four buttons: Power, Measurement/Settings, Measurement Method, and Unit/End.

Operation

Powering on: Press and hold the measurement/settings button for 2 seconds.

Measuring:

Press the measurement/settings button to take a single measurement.
Press and hold the measurement/settings button to take a continuous measurement.

Changing the measurement method:

Press the measurement method button once for area measurement.
Press the measurement method button twice for volume measurement.
Press the measurement method button three times for Pythagoras theorem measurement.

The display will flash to indicate the order of sides that need to be measured for area, volume, and Pythagorean calculations.

Settings and Calibration

To access settings, press and hold the measurement/settings button for 5 seconds until the display shows 'Boot'.

Offset Settings: Press and hold the measurement/settings button for 2 seconds to enter offset settings ('CAL.0'). Adjust the offset between -7mm to 7mm by repeatedly pressing the measurement/settings button. Hold the button for 2 seconds to confirm.
Sound Settings: After offset settings, the display shows sound options. Press the measurement/settings button to toggle sound on/off. Hold for 2 seconds to confirm.
Backlight Settings: After sound settings, the display shows backlight options. Press the measurement/settings button to toggle the backlight on/off. Hold for 2 seconds to confirm.

Changing units: Press and hold the unit/end button to cycle between metres (m), inches (in), and feet (ft).

Changing '0' reference: Press the unit/end button to toggle between measuring from the front or the end of the tape measure.

Clearing Data and Powering Off

Clear data: Press the power button to clear measurement data.
Power off: Press and hold the power button for 2 seconds.

Charging

Plug the USB Type-C charging cable into the charging port.

The tape measure can be slid and secured onto the included clip. The clip can also be passed through a belt or strap for convenient carrying.

Practical help

Common problems

Device not measuring correctly

Check the calibration offset (CAL.0) in settings and adjust between -7mm to 7mm.

Need to clear measurement data

Press the power button to clear the current data.

Laser not turning on

Ensure the device is powered on by holding the measurement/settings button for 2 seconds.

Before use

Charge the device using the provided USB Type-C cable.
Ensure the device is powered on by holding the measurement/settings button for 2 seconds.
Verify the desired measurement unit (m, in, ft).
Check the '0' reference point (front or end of the device).

Specs in practice

Offset adjustment: Allows calibration of the tape measure between -7mm and 7mm to ensure accuracy.
Measurement modes: Includes distance, area, volume, and Pythagoras theorem calculations.

Images and diagrams

The device features a display, laser emitter, and four main buttons: Power, Measurement/Settings, Measurement Method, and Unit/End.

Model compatibility

Requires a standard USB power adapter (not supplied) for charging.
