Ultimate Precision: The HEIGHT MASTER 515 Series Guide

Establishing precise reference heights on surface plates presents daily challenges for metrology labs. Wringing individual gauge blocks together takes valuable time and introduces stacking errors. The HEIGHT MASTER 515 series solves this issue by offering a rigid, staggered block stack for fast height setting and tool calibration.

This guide explores how this master standard elevates accuracy across quality control facilities.

What Is the HEIGHT MASTER 515 Series?

The 515 series is a high-precision reference instrument manufactured by Mitutoyo.

Featuring a rigid column of permanently stacked gauge blocks, this tool moves vertically via a micrometer head. Technicians use the top and bottom surfaces of the staggered blocks to set height gauges, calibrate bore gages, and inspect machined components instantly.

Key Advantages for Quality Control

Integrating a 515 series master into your calibration room delivers clear technical benefits:

• High Reference Accuracy: Delivers sub-micron block accuracy down to 0.001 mm or 0.00005 inches.

• Dual-Direction Reference: Provides reference surfaces on both top and bottom block faces without flipping the column.

• Fast Height Setting: Replaces individual gauge block stacks to speed up tool setting cycles significantly.

• Counter and Digital Display: Features clear mechanical counters or digital displays to eliminate micrometer reading errors.

Common Metrology Applications

Calibration technicians and quality inspectors rely on the 515 series for essential verification tasks:

1. Height Gauge Calibration: Verify electronic and mechanical height gauges across full travel ranges.

2. Surface Plate Inspection: Transfer precise reference height dimensions to workpieces using dial indicators.

3. Setting Measuring Tools: Calibrate bore gauges, depth micrometers, and comparative measuring instruments.

4. Routine ISO Audits: Maintain strict measurement traceability needed for ISO quality compliance audits.

How to Set Reference Heights in 4 Steps

Follow these simple steps to obtain accurate reference measurements:

1. Clean the Base: Wipe the cast iron base and surface plate using alcohol and lint-free cloths.

2. Thermal Equalization: Allow the unit to acclimate to your room temperature before testing.

3. Adjust the Micrometer Head: Rotate the top micrometer thimble to your desired height setting.

4. Zero Your Indicator: Touch your measuring probe to the block face and zero your gauge.

Final Thoughts

The HEIGHT MASTER 515 series converts complex height setting routines into simple, repeatable tasks. By securing reliable reference standards, this durable instrument protects product quality across your manufacturing facility.
