1. Introduction
This manual provides detailed instructions for the safe and effective use of your Dasqua 220° Digital Angle Finder Protractor. Please read this manual thoroughly before operating the device and retain it for future reference. This tool is designed for precise angle measurement in various applications, including woodworking, metalworking, and construction.
2. Product Overview
The Dasqua Digital Angle Finder Protractor is a versatile measuring instrument featuring a 425mm sliding leg, dual bubble levels, and a backlit LCD for clear readings. It is built for durability and accuracy in demanding environments.
2.1 Key Features
- Precise Angle Measurement: Measures angles up to 220° with an accuracy of ±0.2°.
- MTR/COM Modes: Dedicated modes for calculating double miter angles and compound errors.
- 425mm Sliding Leg: Facilitates measurements in tight spaces and offers smooth adjustments.
- Locking Mechanism: Ensures angles are securely held for transfer.
- Dual Bubble Levels: For horizontal and vertical leveling, providing 1.5mm/m accuracy.
- Backlit LCD: 0.1° resolution display for clear visibility in various lighting conditions.
- Durable Construction: IP54 waterproof housing, resistant to dust, water, and oil.
2.2 Components
- Main Body: Houses the digital display and primary measuring arm.
- Sliding Leg (Extension Plate): Extends from the main body for measuring larger angles or reaching into confined spaces.
- Lock Knob: Secures the sliding leg at a desired angle.
- LCD Display: Shows digital angle readings and mode indicators.
- Control Buttons: (On-Off, Hold, 180°, MTR, COM) for various functions.
- Bubble Levels: One horizontal and one vertical for traditional leveling.
3. Setup
3.1 Battery Installation
The device requires 2 x 1.5V LR6 (AA) batteries for the digital display. To install:
- Locate the battery compartment cover, typically on the side or back of the main body.
- Open the cover.
- Insert two AA batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.
The bubble levels operate mechanically and do not require batteries.
3.2 Initial Power On
Press the On-Off button to power on the device. The backlit LCD will illuminate, displaying "0.0" or the current angle.
4. Operating Instructions
4.1 Basic Angle Measurement
- Power on the device.
- Place the main body and the sliding leg against the surfaces whose angle you wish to measure.
- Adjust the sliding leg until it aligns perfectly with the second surface.
- Read the angle directly from the backlit LCD display.
- Use the lock knob to secure the angle for transfer if needed.
4.2 MTR (Simple Miter) Mode
Press the MTR button to enter Simple Miter Mode. This mode is useful for calculating the miter angle required for a joint. The display will show the miter angle (half of the measured angle) needed for a perfect joint.
4.3 COM (Compound Bevel Cutting) Mode
Press the COM button to enter Compound Bevel Cutting Mode. This mode assists in calculating compound angles for complex cuts, such as crown molding or roof rafters. Refer to specific project requirements for interpreting the displayed values in this mode.
4.4 Hold Function
Press the Hold button to freeze the current angle reading on the LCD. This is useful when measuring in awkward positions where reading the display directly is difficult. Press Hold again to release the reading.
4.5 180° Supplementary Angle Display
Press the 180° button to display the supplementary angle (180° minus the measured angle). This is useful for certain applications where the inverse angle is required.
4.6 Zero Setting
To set the current position as the zero reference, fully close the angle finder and press the On-Off button briefly. The display will reset to "0.0". This allows for relative angle measurements.
4.7 Using the Bubble Levels
The angle finder includes two traditional bubble levels for quick horizontal and vertical leveling. These levels operate independently of the digital display and do not require batteries. Align the tool with the surface and observe the bubble to determine level or plumb.
5. Maintenance
- Cleaning: Wipe the device with a soft, dry cloth after each use. For stubborn dirt, a slightly damp cloth can be used. Avoid abrasive cleaners or solvents.
- Storage: Store the angle finder in its included storage bag in a dry, clean environment when not in use.
- Battery Replacement: Replace batteries when the display becomes dim or unresponsive. Remove batteries if the device will not be used for an extended period to prevent leakage.
- IP54 Rating: The device is IP54 rated, meaning it is protected from dust ingress and splashing water from any direction. While durable, avoid submerging the device in water.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or dim. | Low or dead batteries; incorrect battery installation. | Replace batteries with new AA batteries, ensuring correct polarity. |
| Inaccurate angle readings. | Device not properly zeroed; obstruction; damaged sensor. | Perform zero-setting procedure. Ensure surfaces are clean and flat. If problem persists, contact support. |
| Sliding leg does not lock securely. | Lock knob not tightened sufficiently; debris in mechanism. | Ensure lock knob is fully tightened. Clean any debris from the sliding mechanism. |
