Using the Laser Head Safely
The laser source used by the Agilent 5519A/B Laser Head is a Class II,
low power (less than 1 mW) helium-neon laser. It will not cut metal or
even burn paper. Therefore, special safety equipment, such as tinted
glasses or shielding, is not necessary. To avoid possible injury from
prolonged exposure, you should not stare directly at the laser light beam
or the beam reflected from a polished surface. (It is safe to look at the dots
of light reflected on an unpolished surface.)
The Agilent 5519A/B Laser Head complies with U.S. National Center for
Devices and Radiological Health regulations 21 CFR 1040.10 and 1040.11.
These regulations may also apply to any end product into which the
Agilent 5519A/B is designed. Care must be taken to ensure that the end
product complies with all applicable national and local laser safety
regulations.
Using Components Safely
When using any Agilent 5530 calibrator system’s electronic component
(including the laser head, air and temperature sensors, and remote control
unit), observe the following guidelines:
• Before connecting a component, make sure the component and cable
are in good condition.
• If a sensor cable is cut, the cable must be replaced before use.
• Be sure the cables do not present a hazard to people working in the
area. Also, place all cables so they will not be damaged by equipment
or people.
• Hold a cable by its connector (the plug, not the cord) when connecting
or disconnecting it.
• Never force a connector into a port. If they do not join easily, they do
not match. Make sure the connector and port match and that the
connector is properly aligned.
• After inserting a connector into a port, do not twist or turn it.
