Single-sided caliper 1500 mm – workshop construction
Instrument construction and working with large dimensions
Vernier caliper 1500 mm of the MAJd type is a single-sided caliper for external and internal measurements. Read the result from the main scale and the vernier with 0.05 mm graduations — with no batteries or electronics, the instrument is ready for immediate use and unaffected by coolant, dust, or the magnetic field of a machine tool table.
Internal measurements use the same lower jaws — there are no separate upper jaws. The 200 mm long jaws reach deeper into the workpiece, and the measuring surfaces on their backs measure internal dimensions from 20 mm wide. The clamping screw locks the slider, allowing you to transfer the measured dimension without the setting shifting.
With a 0–1500 mm range, technique matters: the workpiece and instrument should be at the same temperature, and the long beam should be supported or handled by two people. Measure without tilting the jaws — over a meter, even slight misalignment noticeably affects the result.

✓ Zero check: before measuring, close the jaws and check that the "0" marks on both scales align.
How to measure with a 0.05 mm caliper – reading the vernier in three steps
Reading principle with a numerical example
A vernier with 0.05 mm graduations divides one millimeter of the main scale into 20 parts — 20 vernier marks span 39 mm of the scale. Taking a complete reading involves three steps:
1Whole millimetersRead the last main scale mark before the vernier's "0" mark
2Aligned markFind the single vernier mark that aligns perfectly with a main scale mark
3Measurement resultMultiply the number of this mark by 0.05 mm and add it to the whole millimeters
View the scale perpendicularly — reading at an angle causes parallax error
Illustrative diagram — 24.70 mm reading on a caliper with a 0.05 mm vernier
324 mm + 14 × 0.05 mm = 24.70 mm
Measurement accuracy per DIN 862 – 0.05 mm vernier
Resolution, maximum permissible errors, and application range
The 0.05 mm graduation specifies reading resolution, not measurement accuracy. Maximum permissible caliper errors increase with the measured length — DIN 862:2015 specifies values for individual ranges and measurement types. In practice, technique also matters: perpendicular viewing, moderate measuring force, and clean measuring faces.
Vernier designs in workshop calipers
| Vernier | Scale construction | Typical application |
|---|---|---|
| 0.05 mm This model | 20 divisions over 39 mm | general workshop tasks |
| 0.02 mm | 50 divisions over 49 mm | quality control, fits |
DIN 862:2015 specifies the maximum permissible errors for individual lengths and measurement types.

Caliper application limits
For tolerances below 0.05 mm, a caliper is no longer sufficient — use a micrometer. Measure at a temperature close to 20°C: steel expands by approximately 11.5 µm per meter per degree Celsius, so a workpiece that is 10°C warmer produces an error of approximately 172 µm over a length of 1500 mm.
Vernier caliper 1500 mm with a 0.05 mm vernier is a workshop instrument for workpieces beyond the capacity of a 150 mm caliper: shafts, housings, spacings, and bores. With no batteries or electronics, it remains serviceable for years — it only requires a clean guide and periodic verification of readings.
Vernier caliper 1500 mm – frequently asked questions
The 0.05 mm vernier with 20 divisions is quick and easy to read reliably, making it sufficient for typical workshop tasks: turning, bench work, and incoming inspection. For fits and tolerances below 0.05 mm, choose the 0.02 mm version or a micrometer.
Read the whole millimeters on the main scale before the vernier's "0" mark, then find the single vernier mark that aligns with a main scale mark. Multiply its number by 0.05 mm and add it to the whole millimeters, e.g., 24 mm + 14 × 0.05 mm = 24.70 mm.
Insert the measuring faces on the backs of the lower jaws into the bore or groove and open them until they make contact — the smallest measurable dimension is 20 mm. Read the result directly from the scale, just as for an external measurement.
Close the jaws to zero and check that the "0" marks on both scales align and no light is visible between the jaws. Every 6–12 months, compare readings against gauge blocks at several points across the range.
