Safety
Precautions
Use indoors only .
Use only within the operational environment listed. Do not use in wet or explosive atmospheres.
Maintain ground. The AC inlet ground is connected directly to the frame of the instrument. To avoid
electric shock, connect only to a mating outlet with a safety ground contact.
Caution: Interrupting the protective conductor inside or outside the oscilloscope, or disconnecting
the safety ground terminal, creates a hazardous situation. Intentional interruption is prohibited.
Connect and disconnect properly. Do not connect/disconnect probes, test leads, or cables while they are
connected to a live voltage source.
Observe all terminal ratings. Do not apply a voltage to any input that exceeds the maximum rating of that
input. Refer to the body of the instrument for maximum input ratings.
Use only power cord shipped with this instrument and certified for the country of use.
Keep product surfaces clean and dry. See Cleaning.
Do not remove the covers or inside parts. Refer all maintenance to qualified service personnel.
Exercise care when lifting. Use the built-in carrying handle.
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 hazardous live electrical quantities.
Cease operation immediately and secure the instrument from inadvertent use.
Operating Environment
Temperature:5 °C to 40 °C.
Humidity: Maximum relative humidity 90% up to 31 °C,
decreasing linearly to 50% relative humidity at 40 °C.
Altitude: Up to 10,000 ft (3,048 m) at or below 30 °C.
Measuring Terminal Ratings (C1-C8 and Ext)
Maximum Input Voltage:50 Ω coupling ≤ 5 Vrms
1 MΩ coupling ≤ 400 Vpk max. (Peak AC ≤ 10 kHz + DC)
derating at 15 dB/decade from 10 kHz to 1.6 MHz,
10 Vpk max.above 1.6 MHz
Caution: Measuring terminals have no rated measurement category per IEC/EN 61010-1:2010.
Measuring terminals are not intended to be connected directly to supply mains.
