Using Limits
The LaserSource supports five different types of limits: current, voltage,
photodiode current, photodiode power, and temperature. Current and voltage
limits are implemented in hardware for high speed response. The other limits are
monitored in software with up to 100ms delay before triggering. There is both a
temperature high and temperature low limit, and if the actual temperature
exceeds either of these limits, the output will be shut off. Likewise, both high and
low limits exist for the sensor (R limits), and the output will be shut off if the
sensor measurement exceeds either of these limits, as determined by settings in
the
Output Off Menu .
Status Messages
The instrument will display status messages indicating several different
conditions that may be of interest to the user. If multiple conditions exist
simultaneously, then the instrument will cycle through each condition, displaying
each status message for approximately one second.
