EMC Warnings

EN 55011 Class A Warning
This is a Class A product. In a domestic environment this product may cause radio
interference in which case the user may be required to take adequate measures.
The XGS-600 was tested with Varian manufactured gauge cables whose pigtails are
connected to the XGS-600 ground stud, and with I/O cables (for remote control, serial
communications and set points) employing combined foil-braid shields and metal shell
connectors with the shields connected to the XGS-600 chassis. Compliance with FCC Part
15 rules and the European Union's EMI requirements cannot be assured unless Varian
supplied gauge cables and foil-braid shielded I/O cables with metal shell connectors are
used. Failure to install the unit in this way may result in the failure to meet the requirements
for radiated emissions and susceptibility.
FCC
This device complies with Part 15 of the FCC rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device must
accept any interference received, including interference that may cause undesirable
operation.

NOTE
The equipment has been tested and found to comply with the
limits for a Class A digital device, pursuant to Part 15 of the FCC
rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is
operated in a commercial environment. This equipment
generated, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction
manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential
area is also likely to cause harmful radio communications
interference in which case the user will be required to correct
the interference at his own expense.
NOTE
It has been observed that transient electromagnetic phenomena
(electrostatic discharges and power line voltage spikes and/or
surges) can cause the XGS-600 to interrupt a measurement
cycle with an error or a blank screen. If this occurs, power
cycle the XGS-600 in order to repeat the measurement.
