4. 3. Instrumentets struktur:

Den sammansatta bildnivån består huvudsakligen av följande delar såsom mikrojusteringsskruv, mutter, graderad skiva, vattenpass, prisma, förstoringsglas, spak samt bas med slät och v arbetsyta.

4. 4. Arbetsprincip:

Den sammansatta bildnivån använder prisma för att få luftbubblor i vattenpasskompositen och förstoras för att förbättra avläsningsnoggrannheten och använder spak- och mikroskruvsändningssystem för att förbättra läskänsligheten. Därför, om arbetsstycket med en lutning på 0,01 mm/m, kan det avläsas exakt i den sammansatta bilden nivån (vattenpasset i den sammansatta bilden nivån spelar huvudsakligen rollen att indikera noll).

5. 5. Driftsmetod:

Placera den sammansatta bilden i nivå på arbetsytan av mätarbetsstycket och gradienten hos mätarbetsstycket orsakar osammanfallande bilder av blåsluftbubblor; Vrid den graderade skivan tills luftbubblans bilder sammanfaller och avläsning kan fås omedelbart. Den faktiska gradienten för mätarbetsstycket kan beräknas med följande formel:

Faktisk gradient=gradientvärde Fulcrum distance Skivavläsning

Fox exempel: Skivläsning: 5 gradienter; Eftersom denna sammansatta bildnivå är fixerad med dess gradientvärde och stödpunktsavstånd, är det gradientvärde: 0,01 mm/m och stödpunktsavstånd: 165 mm.

Så: Faktisk lutning=165 mm 5 0,01/1000=0,00825 mm

(1) före användning, rengör oljedamm med bensin och rengör sedan med absorberande gasväv.

(2) Temperaturförändringar har stor inverkan på instrumentet och därför måste det separeras med värmekälla för att undvika fel.

(3) Under mätningen, rotera den graderade skivan tills luftbubblans bilder helt sammanfaller och sedan kan avläsningarna på både positiva och negativa riktningar tas.

(4) If the instrument is found with in correct zero position, it may be adjusted; Put the instrument on a stable table and rotate the graduated disc to set the tow air bubble images coincide to get first reading a; Then turn the instrument by 180o and put back to its original place. Ra-rotate the graduated disc to get the tow air bubbles coincide to get the second reading b. So 1/2 (α +β ) is the zero deviation of the instrument. Loosen the three supporting screws on the graduated disc and press lightly by hand the embossed adjusting cap; Rotate the disc by 1/2 (α +β) to get the zero deviation and the point line composite; At last fasten the screws.

(5) Efter arbetet måste instrumentets arbetsyta rengöras och beläggas med syrafri, vattenfri, rostskyddsolja och rostskyddspapper; Lägg den i en trälåda och förvara den sedan på en ren och torr plats.

Optical Composite Image Level Maintenance: Antirust Oil & Storage Tips

Proper maintenance ensures your optical composite image level retains its 0.01mm/m precision and durability. Follow these steps to protect its prism technology and mechanical components:

1. Daily Cleaning for Surface Protection

After use, wipe working surfaces (V-groove, edges, lenses) with isopropyl alcohol on a lint-free cloth to remove oils and dust. Use a soft brush for stubborn debris—never abrasives, which can scratch optical parts or damage metal coatings. This preserves the precision ground surfaces (Ra ≤ 0.1μm) critical for accurate readings.

2. Routine Antirust Care for Metal Parts

While the granite base resists corrosion, metal components (screws, levers, hinges) need protection. Apply Storaen’s non-acidic anti-rust oil every 3 months or after moisture exposure:

Apply thinly to threads and pivots with a dropper, avoiding pooling on granite/lenses.
Prevents seizing: Maintains lever mechanism sensitivity (0.001mm precision) for cylindrical slope measurements.

3. Optimal Storage Practices

Store in the included hard case or a dry cabinet to avoid temperature/humidity damage:

Environment: 10°C–30°C, <60% humidity to prevent lens condensation and optical distortion.
Positioning: Lay flat or upright in padded slots; never under heavy objects to avoid misaligning the optical system.
Long-term storage: Reapply anti-rust oil and add a silica packet; inspect 24 hours before use, verifying zero position via 180° rotation calibration.

4. Monthly Functional Inspections

Check performance regularly to ensure reliability:

Bubble clarity: Confirm the composite bubble image aligns smoothly without blur.
Lever movement: Test micro-screws for smooth rotation—stiffness signals needed lubrication.
Flatness check: Use a reference plate to validate factory-calibrated flatness (±0.0003mm/m).

5. Storaen’s Support for Longevity

Leverage our expert services to maintain peak performance:

Factory recalibration: Restores 0.01mm/m precision via ISO-certified equipment for critical applications.

Zero Position Calibration of Optical Composite Image Level: 180° Rotation Method Explained

Accurate zero calibration is vital for your Storaen optical composite image level to maintain its 0.01mm/m precision and ±0.0003mm/m flatness. The 180° rotation method eliminates subtle optical or mechanical shifts, ensuring reliable measurements in critical tasks like CNC machine alignment or aerospace component inspection. Here’s a streamlined, step-by-step guide:

1. Why Calibrate?

Impacts, vibrations, or temperature fluctuations can shift the level’s zero reference, leading to measurement drift. Calibration realigns the bubble vial with the tool’s optical prism and lever system, ensuring consistent baselines for industrial applications where 0.001mm deviations are unacceptable—such as verifying machine tool guides or structural frameworks.

2. Setup Requirements

Storaen optical composite image level (featuring a V-grooved base and micro-adjusting screw)
Certified precision reference flat (e.g., our Storaen granite surface plate, with flatness ≤0.0002mm/m)
A clean, vibration-free workbench in a temperature-stabilized environment (18°C–22°C recommended)

3. Step 1: Initial Measurement

Place the level lengthwise on the reference flat, aligning the V-grooved base with the flat’s central axis. Rotate the micro-adjusting screw until the composite bubble image—created by the 45° prism system—perfectly overlaps in the viewfinder. Record this initial scale reading (A), which reflects the current deviation from true zero.

4. Step 2: 180° Rotation & Second Reading

Carefully flip the level 180° end-to-end while maintaining its longitudinal orientation on the flat (avoid any lateral movement). Adjust the micro-screw again to align the bubble image and record the new reading (B). The difference Δ = |A - B| indicates zero position error; ideal values for Storaen levels should be ≤0.005mm/m.

5. Step 3: Error Correction & Verification

Calculate the target zero position as the midpoint: C = (A + B)/2. Loosen the protective cap on the zero-adjustment screw (typically located near the bubble vial), rotate the screw until the scale reads C, then retighten. Repeat Steps 3–4 until Δ ≤0.002mm/m, ensuring minimal residual error.

6. Pro Tips for Precision

Triple-Check Consistency: Perform 3 calibration cycles, especially after transporting the level or working in environments with temperature swings, to ensure repeatable results.
Lubricate Moving Parts: Apply a drop of Storaen’s non-acidic oil to the micro-screw before adjustment to ensure smooth, backlash-free operation and prevent binding.
Environmental Control: Avoid calibrating near heat sources or drafts, as even minor temperature gradients can affect the granite base’s dimensional stability and introduce errors.
