Introduction
This instruction manual provides comprehensive guidance for the safe and effective use of your SOLA WMD 500 Digital Protractor. The SOLA WMD 500 is designed to measure, draw, and transfer angles quickly and easily with an accuracy of ±0.3°. Please read this manual thoroughly before operating the device and retain it for future reference.
Product Overview
The SOLA WMD 500 Digital Protractor combines the functionality of a protractor and a ruler, making it a versatile tool for various applications, including metalworking and woodworking.
- Integrated Stop Edge: Features an integrated stop edge for accurate and reliable measurements, allowing it to function as a try square.
- Ruler Functionality: Both legs include a continuous millimeter/centimeter scale for use as a standard ruler.
- Robust Construction: Constructed with reinforced aluminum legs and stiffening ribs for durability. The black anodized finish with laser scaling ensures wear resistance and readability.
- Digital Angle Measurement: Measures outer and inner angles with a precision of ±0.3°.
- Manual Leg Fixing: Allows for powerful, manual fixing of the legs to precisely transmit angles.
- Hold Function: Enables saving of measurement readings.
- Zero Function: Provides a zero reference for incremental measurements.

Setup
Battery Installation
The SOLA WMD 500 Digital Protractor requires one CR2032 button cell battery (included).
- Locate the battery compartment on the side of the digital display unit.
- To open the battery compartment, press firmly with two fingers on the designated points and slide the cover open. This child-safe design prevents accidental opening.
- Insert the CR2032 battery with the positive (+) side facing upwards.
- Close the battery compartment cover securely until it clicks into place.

Operating Instructions
Power On/Off
- Press the power button (⏻) to turn the device on or off.
- The device will automatically shut off after a period of inactivity to conserve battery life.
Measuring Angles
- Loosen the manual fixing knob to allow the legs to move freely.
- Position the protractor against the object or surface to be measured, ensuring both legs are flush.
- Read the angle directly from the LCD display.
- Tighten the manual fixing knob to lock the legs in place for angle transfer.

Hold Function
- Press the "HOLD" button to freeze the current angle reading on the display. This is useful for recording measurements or when the display is not easily visible during measurement.
- Press the "HOLD" button again to release the reading and return to live measurement.
Zero Function (Incremental Measurement)
- To set a new zero reference for incremental measurements, position the protractor at the desired starting angle.
- Press the "ZERO" button. The display will show "0.00°", and subsequent angle movements will be measured relative to this new zero point.
- To return to absolute angle measurement, press the "ZERO" button again.

Maintenance
- Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the display or finish.
- Storage: Store the protractor in a clean, dry place away from direct sunlight and extreme temperatures.
- Battery Replacement: Replace the CR2032 battery when the display indicates low power or becomes dim. Follow the battery installation steps in the "Setup" section.

Troubleshooting
- Display Not Working:
- Check if the device is powered on.
- Ensure the battery is correctly installed with the correct polarity.
- Replace the CR2032 battery if it is depleted.
- Inaccurate Readings:
- Ensure the protractor legs are fully extended and flush against the measurement surface.
- Verify that the ZERO function has not been accidentally activated, leading to incremental measurements.
- Clean the measurement surfaces of the protractor to remove any debris.
- Legs Not Moving Smoothly:
- Loosen the manual fixing knob completely.
- Check for any obstructions or debris in the hinge mechanism.
