Probe Angle Adjustment

The angle of your probe can be adjusted by loosening and then tightening three 

knobs on the positioner arm/universal holder. 

Figure 6

 shows the location of these 

three knobs. If knobs (1) and (2) are loose, there is a possibility that your probe may 

fall over. Make sure these knobs are securely fastened during any measurements. 

Knob (3) may be left loose when the probe is used vertically. If the probe is to be used 

with some slope against the board then it must be tightened as well.

Figure 7

 on page 10 shows a series of pictures displaying some of the axes that can 

be rotated about by loosening and tightening the three knobs shown in 

Figure 6

.

CAUTION

During any measurements, always securely tighten knobs (1) and (2) to avoid the 

possibility that the probe may fall over.
