10. CHANGING THE PROBE HOLDER
To change the probe holder, raise the probe using the UP key (13) to the upper stop. Remove
it while pushing it up. Introduce the new probe holder
Turn correctly the eccentric probes. Clamp firmly but do not force, using the 2.5 mm imbus
key.
Make sure to keep the same weight (for the part probe + the probe holder) while using other
probes : 2 oz
±
0.5 oz (refer to the indications provided with the set of probe holders).
The probe constant must be measured, see chapter 5.2.
11. ADJUSTING THE MEASURING FORCE
The measuring force is factory set to 1 oz. Only proceed with a change if this is necessary.
The force can be adjusted within a range of 0.9 to 1.8 oz. To do this :
1. Remove the cover (21).
2. Remove the nose (12) by sliding it upwards
↑
in order to gain access to the
adjustment orifice.
3. Insert the carriage adjusting screw into the orifice.
4. Turn the screw clockwise to increase the measuring force. Check the latter using the
force measuring device (Correx type). Too low pressure may affect repeatability. 1
turn = 0.035 oz.
5. Refit the nose and cover.
12. REPLACING THE BATTERIES
As soon as the autonomy of the Z_CAL becomes unsufficient, the batteries should be
changed (lifespan about 4 to 6 years).
1. Purchase a battery pack from your Sylvac agent.
2. Disconnect the instrument, turn it upside down and lay it on its cover (21).
3. Unscrew the protection plate.
4. Disconnect the battery pack, note the the connector’s polarity.
5. Connect the new pack and refit the protection plate.
