32 ST-133/ST-133A Controller Manual Version 2.H
Getting Started
1. Set the spectrometer entrance slit width to minimum (10 µm if possible).
2. Turn on the controller power.
Note: The detector overload alarm may sound briefly and then stop. This is normal
and is not a cause for concern. However, if the alarm sounds continuously, even with
no light entering the spectrograph, something is wrong. Turn off the power and
contact the factory for guidance.
3. Turn on the computer power.
4. Start the application software.
Note: If using software other than WinSpec/32 or WinView/32, these instructions
will have to be appropriately adapted.
Setting the Parameters
5. Set the software parameters as follows (following settings are keyed to WinSpec32
software)
Note: This procedure presupposes that the user is basically familiar with the
software. If this is not the case, it may be advisable to review the software manual or
to at least have it as a handy reference while performing this procedure.
Controller/Camera tab page (Setup menu - Hardware)
• Controller type (Setup-Hardware): ST-133
• Controller version: 3 or higher
• Camera type (Setup-Hardware): Select array installed in your detector.
• Shutter type: As appropriate for your detector.
• Readout mode: As appropriate for your detector chip.
Temperature: -15°C (set from Detector Temperature dialog box, accessed by
selecting Detector Temperature on the Setup menu).
The temperature should drop steadily, reaching -15°C in about ten minutes (typical).
At that point the green Temp Lock LED on the Analog/Control module will light
and there will be a locked indication at the computer monitor, indicating that
temperature lock has been established. Note that some overshoot may occur. This
could cause temperature lock to be briefly lost and then quickly re-established. If you
are reading the actual temperature reported by the application software, there may be
a small difference between the set and reported temperature when lock is established.
This is normal and does not indicate a system malfunction. Once lock is established,
the temperature will be stable to within ±0.05°C.
Note: In the case of a TE series camera, connect a source of liquid coolant. For
purposes of these checks, ordinary tap water will be fine. Liquid cooling may be
necessary with type TE cameras (some CCDs, such as the SITe 512x512, don’t
operate correctly unless cooled to approximately -40°C.) With liquid cooling you
will be able to cool type TE cameras to -50°C. Without liquid cooling, a TE camera
can only lock to -5°C, unless it is a model having forced air cooling, in which case
temperature lock down to -40°C can be achieved.
