7 Optional Accessories
7.1 Height Support & Probe Sheath
When the measured surface of the work-piece is smaller than the bottom surface of the instrument, you
can use the optional accessory probe sheath and height support as auxiliary support to complete the
measurement (as shown below).
Height Support and Probe Sheath
Notes
：
1. Length is not less than the driving stroke of the measurements, otherwise the probe may fall
out work-piece, resulting in failure;
2. Confirm measuring platform are locked;
3. Prior to measuring, adjust the height-adjustable legs to a suitable height with calipers.
7.2 Height Lifting Pillar
Height lifting pillar can help to adjust the position more accurately between the work-piece and the
instrument, make the operation more stable and reliable and expand the measuring space, so it can do
roughness measurement of a larger volume work-piece surface.
Using a height support, pay special attention to misuse of the probe close to the work-piece, to prevent
damage to the probe.
When the probe is close to the work-piece surface, the pointer position of the stylus is at the middle
position of the display. When the measured Ra value is smaller recommend measurement platform and
use the remote control to start the measurement, in order to reduce the impact of the external
environment. When using special probes, such as holes, deep grooves and curve surface probe, etc.,
you must use the column height support or other height adjustment device.
