3. Turning on/off and Initializing the Product
3.1 Initializing the Laser
Before Starting
Procedure 1. Make sure the key-lock switch on the front panel is in STBY position.
2. Set the rear panel MAINS power switch to the I position to turn on the product.
3. Turn the front panel key to the right to set it to ON .
• The product performs the initialization routine, the message
Initializing
appears .
The T100S-HP performs self-checks during initialization sequence. Under MODE,
the LED of the APC key is lit. Power setting is set to zero before the laser is
powered up.
• The message
Referencing…
appears to indicate that the system is
performing its self-calibration (internal wavelength referencing). This message
clears once the laser is initialized and ready for operation.
For optimum system performance, we recommend you to let the T100S-HP
perform its self-calibration routine when turning on the system.
4. To skip the self-calibration step (skip
Referencing
): while the message
Initializing…
is displayed, press the 0 key.
Once the initialization routine is complete, the laser output is ready to be enabled:
• The cavity laser is tuned on its central emission wavelength (depending on the
model).
• In the DATA area:
• The first display shows the wavelength ( λ )
• The second display shows the output power (P)
• The third display shows the message
Disabled .
Caution
If the T100S-HP has previously been shut down (see section Shutting Down
the Product, p. 26 ), you must wait at least thirty seconds before initializing
the laser again.
Warning
While the system initializes the laser, it performs the internal wavelength
referencing just after the initialization routine: the T100S-HP produces a laser
beam, even if the system is in
Disable mode.
To avoid eye damage, do not look into the laser output or into the end of an
optical cable. Even though the laser radiation is not visible, the intense
infrared light can cause eye damage.
Caution
Do not switch the product off before the system is fully initialized.
