all times;
Once
Gain
has been initially set as
2
Gain
=
Min
Max
−
, the user can then change
Gain
manually.
In
Manual
mode the user can adjust
Gain
and
Level
manually. Use this measurement
mode when you need more freedom to define
Level
and
Gain
values. This mode provides
the flexibility to bring both MIN and MAX values to the desired cut-off levels and to adjust
the temperature interval to a minimum, thus maximizing color resolution. Using the Manual
mode efficiently requires more experience with both thermal imaging techniques and specific
knowledge of the equipment being inspected. However, Manual mode provides the best
possible image definition as to the specific inspection situation at hand, both from a thermal
resolution and temperature level standpoint.
It is worth noting once again the importance of properly focusing the Ti30 Imager. Once a
properly focused image is stored and downloaded to a computer, you can use the InsideIR
software to adjust the level and gain of an individual image (perfecting the image quality on
the PC in a controlled office environment versus in the field).
Tip:
The minimum temperature interval between the MIN and MAX values is 5
°
C / 9
°
F. It is important to remember that by decreasing the difference between MIN and
MAX values increases the likelihood of
image noise
. Only bring the difference
between MIN and MAX to the minimum when you absolutely need the best
thermal resolution available.
Gain and Level Thumbwheels
The
Level Thumbwheel
control increases
Level
by pulling the wheel towards the
back of the imager and decreases
Level
by pushing the wheel forward towards the front of
the imager. When
Level
is increased both MIN and MAX values increase accordingly and
when
Level
is decreased both MIN and MAX values are decreased accordingly.
The
Gain Thumbwheel
control increases
Gain
by pulling the wheel towards the back
of the imager and decreases
Gain
by pushing the wheel toward the front of the imager.
When
Gain
is increased, MIN value decreases and MAX value increases accordingly. When
Gain
is decreased, MIN value increases and MAX value decreases accordingly.
Gain
can be
decreased up to the point when the difference between MIN and MAX values is 5
°
C / 9
°
F.
Note:
Both wheels have endless adjustment action (no détente).
