44 MicroMAX System User Manual Version 6.C
• In Acquire mode, every frame of data collected can be automatically stored (the
completed dataset may include multiple frames with one or more accumulations).
This mode would ordinarily be selected during actual data collection. One limitation
of Acquire mode operation is that if data acquisition continues at too fast a rate for it
to be stored, data overflow will eventually occur. This could only happen in Fast
Mode operation.
The remainder of this chapter is organized to first talk about the system on/off sequences.
Then "First Light" procedures for im
aging and spectroscopy applications follow: these
procedures provide step-by-step instruction on how to initially verify system operation.
The last three sections discuss factors that affect exposure, readout, and digitization of the
incoming signal. By understanding these factors and making adjustments to software
settings you can maximize signal-to-noise ratio. For information about synchronizing
data acquisition with external devices, please refer to Chapter 6, Advanced Topics.
EMF and Xenon or Hg Arc Lamps
Before You Start, if your imaging system includes a microscope Xenon or Hg arc lamp,
it is CRITICAL to turn off all electronics adjacent to the arc lamp, especially your
digital camera system and your computer hardware (monitors included) before turning on
the lamp power.
Powering up a microscope Xenon or Hg arc lamp causes a large EMF spike to be
produced that can cause damage to electronics that are running in the vicinity of the lam
We advise that you place a clear warning sign on the power button of your arc lamp
reminding all workers to follow this procedure. While Princeton Instruments has taken
great care to isolate its sensitive circuitry from EMF sources, we cannot guarantee that
this protection will be sufficient for all EMF bursts. Therefore, in order

ystem On/Off Sequences
If your system is configured for the USB 2.0 communication interface, you must follow
the system on/off sequences as stated below. These sequences ensure that
is established and maintained between the camera and the host computer:
The MicroMAX camera must be powered ON before WinView/32 or WinSpec/32 is
opened to ensure communication between the camera and the computer. If WinView
or WinSpec is opened and the MicroMAX is not powered ON, many of the function
will be disabled and you will only be able to retrieve and examine previously
acquired and stored data. You must close WinView or WinSpec, power the camera
ON, and re
new data.
WinView/32 or WinSpec/32 must be closed before powering the camera OFF. If you
power the camera OFF before closing WinView or WinSpec, the communication link
with the camera will be broken. You can operate the program in a playback mode
(i.e., examine previously acquired data) but will be unable to acquire new data until
you have closed WinVie
