The LASer:LIMit:V command sets the LASER compliance voltage limit value.
Syntax Diagram
Parameters An that represents the LASER limit voltage, in volts.
Notes The voltage limit setting is useful for laser protection. When the maximum operating
voltage of a laser is known, the user may set the voltage limit to a value slightly higher
than the maximum operating voltage. Then, if the laser is accidentally disconnected, the
current source will quickly sense the over-voltage and shut off.
In local operation, the voltage limit is entered by selecting the COMP V parameter,
pressing and holding in the (PARAMETER) SET switch. Turn the adjust knob until the
desired value is displayed and then release the SET switch.
Examples "LAS:LIM:V 5.0" -action: the LASER compliance voltage limit is set to 5.0 V.
":Laser:Limit:V 4.60" -action: the LASER compliance voltage limit is set to 4.6 V.
The LASer:LIMit:V? query returns the value of the LASER compliance voltage limit
setting.
Syntax Diagram
- where the response is the LASER limit voltage setpoint.
Notes The voltage limit is valid for all modes of Laser operation.
In local operation, the voltage limit is seen by selecting the COMP V parameter, pressing
and holding in the (PARAMETER) SELECT switch.
Examples "LAS:LIM:V?" -response: 4.5, means the laser compliance voltage limit is 4.5 V.
"Laser:LIM:V?" -response: 10.0, means the laser compliance voltage limit is set to
10.0 V.
