Safety Features
Protection Software Key
For additional safety, you cannot activate the WDM Laser Source (with the
application ON/OFF switch) without unlocking it by entering the security
password “safekey”when prompted.
Note: This password cannot be changed and is the same for all instruments
requiring a software key.
Once the instrument has been unlocked, the Unlock button remains
pressed and the icon shows a closed interlock.
Five-Second Safety Delay
The IQS-2400 WDM Laser Source application provides a five-second safety
delay between the instrument activation and actual light emission. During
this five-second delay, you may cancel the activation of the laser by using
the instrument activation/deactivation switch, by opening the interlock
circuit or by using the software key button.
Note: The source emits a weak signal during the five-second delay.
