- Zero reset: Sets any angle as a reference zero for relative angle measurement
- Hold function: Locks the current reading for easy recording and reading
- Simple calibration: Calibrates using a known-angle surface without special fixtures
- Auto-orienting display: LCD remains upright for clear reading at any angle (Pro 360 feature)
- Low-power design: Up to ~500 hours of battery life for long-term field use

Operating Instructions for Mitutoyo Pro-360-950-317 Digital Protractor
Quick Start Guide
Basic operation: Press ON/OFF → wait 5 seconds for stabilization → place firmly on the surface → press ZERO to set zero → press MODE to change display mode.
Key functions: HOLD to lock reading, ALT to switch horizontal/vertical reference, no internal calibration (requires external reference surface).
- Power On & Basic Measurement
- Power on
Short press ON/OFF; the LCD lights up and enters 360° measuring mode (default horizontal reference: 0.0° horizontal, 90.0° vertical).
- Stable reading
Place the reference base firmly against the measured surface and wait 5 seconds for the reading to stabilize.
- Read the angle
360° mode: 0.0°–360.0°
180°×2 mode: press MODE; 0.0°–180.0° (dual direction)
90°×4 mode: press MODE; quadrant-based display
- Power off
Hold ON/OFF for 3 seconds to shut down; auto power-off for energy saving.
- Core Function Operations
| وظيفة | عملية | طلب |
| Zero Reset (Relative Measurement) | Press ZERO/ON to set current surface as 0.0° | Relative angles, workpiece tilt, assembly gaps |
| Reading Hold | Short press HOLD to lock; press again to release | Recording in hard-to-reach areas |
| Reference Switch (ALT) | Short press ALT to toggle horizontal/vertical (0.0° ↔ 90.0°) | Squareness, angle to vertical surface |
| Display Mode Switch | Press MODE to cycle: 360° → 180°×2 → 90°×4 → 360° | Different measuring scenarios |
| Battery Replacement | Open rear cover, install 6LR61 9V battery | Long field use |
- Calibration Method (No Internal Calibration)
This model has no built-in self-calibration; use a known-angle standard surface (square, master protractor, precision V-block).
Steps:
- Clean the standard surface and instrument base.
- Place on the standard surface (على سبيل المثال, 90°) and wait 5 ثواني.
- If the reading deviates, note the offset and correct manually or send for service.
- Verify at 0°, 45°, and 90° for full-range accuracy.
- Typical Application Procedures
- Machine tool leveling
Power on → 90°×4 mode → place on guideways → read tilt → adjust feet to 0.0°±0.1°.
- Workpiece squareness inspection
Power on → press ALT for vertical reference → measure side → read deviation.
- Relative angle measurement
Power on → zero on reference → measure target surface → read relative angle.
- Flatness inspection
360° mode → measure multiple points → record max/min difference.
- عملية & نصائح الصيانة
قبل الاستخدام: Clean all contact surfaces; avoid strong magnetic fields.
أثناء الاستخدام: Handle gently; use fixtures for curved surfaces.
صيانة: Verify every 3 شهور; store dry at -10°C~+40°C; remove battery during long storage.
- استكشاف الأخطاء وإصلاحها
| Symptom | Cause | حل |
| Unstable / fluctuating reading | Poor contact, vibration, magnetic interference | Clean surfaces, secure unit, move away from magnets |
| Large measurement error | Uncalibrated, dirty base | Recalibrate, clean base |
| No display | Dead battery / poor contact | Replace 6LR61 9V battery, check contacts |
| Buttons unresponsive | Wear or moisture | Send for professional repair |
- أمان & Compliance
Do not disassemble the unit; this voids warranty and damages the sensor.
