8 Changing impact body
This tester has a very unique feature, which impact device can convert between D and DL simply by
changing impact body. This two-in-one probe is equivalent to two individual probes. With this optional
accessory, you can take measurement at very narrow surface such as slot bottom, gear tooth that probe
D cannot match. Please refer to the following steps to change impact body. Unscrew the support ring
from the tester and let the impact body D out. Insert the impact body DL into probe and screw the guide
tube onto the probe.
Tester equipped with DL impact device
Note: The block D supplied with the new tester indicates the standard HLD value instead
of LDL value, when measuring on standard block D with DL probe, the reading is LDL
value, which is different from the HLD value marked on the block. If you need standard
LDL value, please contact with the manufacturer.
