2. Adjust the trigger level on the oscilloscope.
3. Connect the Video BNC connector to the analog input of the oscilloscope.
4. Set the time scale of the oscilloscope to display the desired portion of the video sig-
nal. The scan of the photodiodes lasts 1ms in 1KHz mode or 3.8ms in 263Hz mode.
NOTE: If the scanned signal is less than 1.0V, the sarcomere length may be incorrectly
calculated.
NOTE: If no oscilloscope is available, view the signal amplitude by pressing the Display
button. Adjust the amplitude by adjusting the Laser Power knob.
If the laser pattern becomes weak compared to the background (peak height less than
twice the maximum background), then check the quality of the laser pattern with an
oscilloscope as described above.

Understanding the Display
The default display is two lines and shows the temperature of both channels. If you
prefer, you may display information from a single channel, either Channel 1 or Channel 2.

Live Temperature Readout–The temperature of the cuvette connected to Channel 1
displays in the fi rst line, and the Channel 2 cuvette temperature appears in the second
line.
NOTE: The maximum temperature the sensor can monitor is 62.9ºC. If a channel has no
cuvette plugged in, the display will default to the maximum temperature display.
Alarm State–If the temperature of the cuvette is within the defi ned range, OK displays
on the screen. If the temperature falls below the defi ned range, a low alarm sounds and
LO appears on the display. HI appears on the display and a high alarm sounds if the
temperature exceeds the defi ned range. If the alarm is not enabled, no audible alarm is
heard.
