Calibration check

Use the program Values to check if the detector readings are within specified tolerances.

Quick check

1. Make a mark to mark out the position of the detectors.
2. Tap to zero set the value.
3. Place a shim under the magnet base to lift the M-unit 1 mm (100 mils). The M-unit’s reading shall correspond to the movement within 1 % (±1 mil or ±0.01 mm).
4. Remove the shim from the M-unit.
5. Tap to zero set value.
6. Place the shim under the magnet base of the S-unit. The S-unit’s reading shall correspond to the movement within 1 % (±1 mil or ±0.01 mm).

1. Make sure that the distance is kept.

2. Parallel lift to a known distance. Shim exactly 1 mm (100 mils).

NOTE! The shim must be exactly 1 mm (100 mils).

Precision check

1. Fasten one of the measuring units in a machine tool.
2. Tap to zero set value.
3. Move the unit a known distance. Use the movement of a machine tool spindle.
4. The fastened unit’s reading shall correspond to the movement within 1 %.

Move the unit a known distance.

NOTE! In this example it is only the unit fastened in the machine that is checked.
