Measurement Category II (as referenced in IEC 60664) connections require protection for high transient overvoltages often associated with local AC mains connections. Certain Keithley measuring instruments may be connected to mains. These instruments will be The following safety precautions should be observed before using this product and any marked as category II or higher.

Power on the 4200A-SCS The 4200A-SCS operates from a line voltage of 100 V to 240 V at a frequency of 50 Hz or 60 Hz. Make sure the operating voltage The power cord supplied with the Model in your area is compatible. 4200A-SCS contains a separate protective earth (safety ground) wire for use with grounded outlets.

To power on the 4200A-SCS: When fi rst starting a Clarius+ application, you must answer “Yes” to an on-screen license agreement. Answering “No” Make sure the power is off. The power switch, on the front makes your system nonfunctional until you reinstall the panel in the lower right corner, is not lit when power is off.
