Optimize Image Parameters
To optimize the image parameters, refer to instructions that
follow.
Gain Levels
The [Gain 1] and [Gain 2] buttons have adjustment ranges
from 1 to 8. Increases of the gain value cause the image
to become brighter. Adjust gain levels depending on your
needs, the type of the examination, and the depth of
penetration of external light conditions.
You can also adjust gain levels with your fingers or the stylus.
Gain 1 can be adjusted in the active field located at the
top of the scanning sector. Gain 2 can be adjusted at the
bottom of the sector.
Probe Frequency
The 4Vet operates with broadband probes that are able to
emit signals of different frequencies.
The range of available frequencies depends on the type of
the probe. Refer to Appendix D, Specifications.
To change the signal frequency, use the [MHz -] and [MHZ +]
