Roundtest RA-120 and RA-120P
Series 211 - Form Measuring Instrument
This is a compact roundness tester with D.A.T. (Digital Adjustment Table) function.
The Roundtest RA-120 and RA-120P give you the following benefits:
– The turntable displays centering and leveling adjustments digitally, making this challenging task
easy enough for even an untrained operator to perform, through these four simple steps:
1. Preliminary measurement of two cross sections on the workpiece.
2. The centering and leveling adjustment values are displayed.
3. The digital micrometer heads on the rotary table are adjusted to match the values displayed.
4. Centering and leveling is complete. [Centering range : ±3 mm - Leveling range : ±1°]
