Pyrocam IV Operator’s Manual Document No. 50337-001 Rev F 2/21/2017 Page 24
STEP 3. Click on the Ultracal button on the Source tab or Quick Access
Toolbar to initiate the Ultracal cycle.
STEP 4. Upon completion, the Ultracal checkbox will turn ON, a measured
signal to noise ratio of the camera in RMS dB will be computed and
displayed and a Green will illuminate in the status bar. Be patient… this
can take more than a minute if the trigger rate is slow or if you are using
pulse mode 1 (single-shot mode).
3.5.4 Ultracal Status Indicator
The Pyrocam powers up in an un-calibrated state. Each time it is powered down all
previous calibration data is lost. BeamGage indicates that an Ultracal cycle has not
been performed by displaying a GRAY in the Status bar.
When a valid calibration cycle has been performed and is in effect, the status indicator
will appear GREEN . As long as you do not disturb the Pyrocam set up or trigger
timing, the indicator will remain GREEN.
A RED status bar indicator is a warning to the operator than trigger conditions may
be affecting the quality of the collected data. If the rate change is slight then the data
may still be useful. The operator must use their own judgment in evaluating and
accepting the results under this condition.
The only conditions that will cause the button to turn RED are listed above in section
3.5.2 as items 1, 2, 3, 4, and 5. Items 6 and 7 are not detectable by the camera and are
left for the operator to monitor.
