It is Probe type C with 3 Nmm (vs. 11 nMm for probe D), its suitable for surface-treated materials or small objects, however it must fulfill the requirements specified by the standards and by Proceq.
Yes, very easy and has very high repeatability. The exception is a DL probe, which has presumably higher inertia due to the elongated impact body and unstable base of the probe. Due to this, the probe is known to be...
Yes, very easy and has very high repeatability. The exception is a DL probe, which has presumably higher inertia due to the elongated impact body and unstable base of the probe. Due to this, the probe is known to be slightly user-dependant.
Yes, but only if they follow the requirements specified by Proceq. Samples can be measured as coupled and uncoupled.

The wall thickness and mass of the test object can influence hardness testing according to Leeb or UCI. Applicable standards require a minimum wall thickness and minimum mass. If these requirements cannot be fulfilled, additional measures such as coupling or supporting the specimen are necessary.
Uncoupled: Requirements for the Leeb method (impact device D, DL, DC, E, and S) are that parts must weigh at least 5 kg (11 lbs) and have a minimum thickness of 25 mm (0.98 inches) to prevent them from yielding or flexing under the large force created during the time of impact. For the Leeb G this is accordingly higher with a mass of 15 kg (33 lbs) and a thickness of 70 mm (2.73 inches), while for Leeb C, a mass of 1.5 kg (3.3 lbs) and a thickness of 15 mm (0.59 inch) is already enough.
On solid support: 2 kg/4.5 lbs (D, DC, DL, E, S), 0.5 kg / 1.1 lbs (C), 5 kg / 11 lbs (G)
Coupled: 0.05 kg / 0.2 lbs (D, DC, DL, E, S), 0.5 kg / 1.1 lbs (C), 0.5 kg / 1.1 lbs (G)
