Use of extensions on PHS-2 system
The PHS-2 has a range of extensions and adaptors. For the best system accuracy, use the following guidelines:
- Always use the probe at the minimum radius - only use extensions when necessary and then the shortest needed to reach a feature
- If an extension is necessary, use the lightest probe and extension combination
Preferred combinations
Extension / adaptor | Radius to probe tip with TP2 or TP20 probe and 30 mm stylus |
HA-8 | 114 mm |
HA-8 + PEL1 | 164 mm |
HA-8 + PEL2 | 214 mm |
HA-8 + PEL3 | 314 mm |
HE-330 | 330 mm |
HE-500 | 500 mm |
HE-750 | 750 mm |
NOTE: When using extensions it is recommended that two C-spanners should be used to fit the probe.
