Precautions
Use proper power cord. Use only the power cord shipped with this
instrument and certified for the country of use.
Maintain ground. This product is grounded through the power
cord grounding conductor. To avoid electric shock, connect only to a
grounded mating outlet.
Connect and disconnect properly. Do not connect/disconnect
probes or test leads while they are connected to a voltage source.
Observe all terminal ratings. Do not apply a voltage to any input
(C1, C2, C3, C4 or EXT) that exceeds the maximum rating of that
input. Refer to the front of the oscilloscope for maximum input
ratings.
Use only within operational environment listed. Do not use in
wet or explosive atmospheres.
Use indoors only.
Keep product surfaces clean and dry.
Do not block the cooling vents. Leave a minimum six-inch gap
between the instrument and the nearest object. Keep the underside
clear of papers and other objects.
Do not remove the covers or inside parts. Refer all maintenance to
qualified service personnel.
Do not operate with suspected failures. Do not use the product
if any part is damaged. Obviously incorrect measurement behaviors
(such as failure to calibrate) might indicate impairment due to
hazardous live electrical quantities. Cease operation immediately and
sequester the instrument from inadvertent use.
