Full battery charging time - 14 hours. Always look after device when charging. Also, the device
can be charged by connecting to a PC or Power Bank.
If do not use the device, should charge the batteries at least once per two month to avoid batteries
from failure.
2.3.4 Measurements using Ultrasonic Contact Impedance Probe U1
LIMITATION: limited use for measuring products with a coarse-grained structure (e.g., cast iron)
or a weight of less than 100 grams, or a thick less than 1 mm! Typically, such
products must be ground to a massive polished plate.
1. Before measurements, it is necessary to prepare the surface according to p. 2.3.1.
2. Plug the UCI probe.
3. Turn on the device by long pressing < >.
4. As the probe is already connected, the device immediately goes to the <MEASUREMENTS>
section (Figure 2.5).
Figure 2.5 – <MEASURING> section
5. Select the required hardness scale, press < > to assess the selection menu (Figure 2.6),
than select the scale with < > and < > keys (the Rockwell C (HRC), Brinell
(HB), Vickers (HV), Rockwell B (HRB), Shore (HS), Leeb (HL), the measurement of tensile
strength (
σ
v) for carbon pearlite steel (MPA), user scales (U1, U2, U3)).
