4. Setup
4.1 Charging the Battery
The Inkerma RS-393 comes with a built-in rechargeable lithium-ion battery. Before first use, it is recommended to fully charge the device.
- Locate the Type-C charging port on the side of the device.
- Connect the provided Type-C charging cable to the device.
- Connect the other end of the cable to a standard USB power adapter (not included) or a computer USB port.
- The battery indicator on the display will show charging status. A full charge typically takes a few hours.

4.2 Powering On/Off
- To Power On: Press the Start Measurement button (up arrow icon). The display will light up.
- To Power Off: Press and hold the Clear / Power off button (trash can icon) for a few seconds. The device will also automatically power off after a period of inactivity to conserve battery.
5. Operating Modes
The RS-393 offers multiple measurement modes to suit various needs. Use the Switch Measurement Modes button (grid icon) to cycle through them.
5.1 Single and Dual Laser Measurement
- The device supports both single and dual laser modes. In dual laser mode, it measures from both ends simultaneously.
- To switch between bilateral and single laser modes, refer to the on-screen indicators or specific button functions detailed in the user manual.
5.2 Continuous Measurement Mode
This mode allows for dynamic measurement, displaying real-time distance changes as you move the device.
- Select the continuous measurement mode.
- Move the device slowly towards or away from the target. The display will continuously update the distance.
- The device will also record maximum and minimum values during continuous measurement.

5.3 Area and Volume Measurement
These modes simplify calculations for rectangular areas and volumes.
- Area Measurement: Select the area mode. Measure the length and width. The device will automatically calculate and display the area.
- Volume Measurement: Select the volume mode. Measure the length, width, and height. The device will calculate and display the volume.
5.4 Pythagorean Mode
The Pythagorean mode allows for indirect measurements of height or width using the Pythagorean theorem.
- Select the desired Pythagorean mode (e.g., single Pythagorean, double Pythagorean).
- Follow the on-screen prompts to take the required measurements (e.g., hypotenuse, base).
- The device will calculate the unknown side.
5.5 Angle Measurement
The integrated angle sensor provides real-time angle readings.
- The angle is displayed on the screen as you tilt the device.
- The measurement range for angles is 0° to 90°.

9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery is low or depleted. | Charge the device using the provided Type-C cable. |
| Inaccurate measurements. | Laser lens is dirty; measurement surface is reflective or too bright; device is not stable. | Clean the laser lens. Measure against a non-reflective, solid surface. Ensure the device is stable during measurement. |
| Laser beam is not visible. | Operating in very bright conditions; laser is off. | Move to a less bright environment or use a target plate. Ensure the laser is activated. |
| Cannot switch modes/units. | Buttons are stuck or unresponsive. | Ensure buttons are pressed firmly. If unresponsive, try restarting the device. |
