WARNING
Dangerous voltage levels, capable of causing death, are present in this instrument.
Use extreme caution when handling, testing, and adjusting this instrument.
Ground the Instrument
To avoid electric shock, the instrument chassis and cabinet must be grounded with the
supplied power cable's grounding prong.
DO NOT Operate in an Explosive Atmosphere
