RayTek ThermoView Ti30 user manual Tip

Page 45

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.

Tip:

The minimum temperature interval between the MIN and MAX values is 5

C / 9

 

θ

 

θ

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 decrease 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 5θ C / 9θ F.

Note: Both wheels have endless adjustment action (no détente).
