3.5 Connecting Probes
• For the 720254 (4CH 1M16)
Maximum input voltage (at a frequency of 1 kHz or less)
• In combination with an isolated probe (10:1) 700929 or (100:1) 701947, or a passive
• In combination with a safety cable (1:1) (701901+701954)
• Direct input (cable that does not comply with the safety standards)
Maximum allowable common mode voltage (at a frequency of 1 kHz or less)
• In combination with an isolated probe (10:1) 700929 or (100:1) 701947, or a passive
• Direct input (cable that does not comply with the safety standards)
Over-Range Indication
If over-range is indicated, the DL850E/DL850EV may be receiving a voltage higher than the
observed waveform or measured waveform values. To prevent electric shock, change the
vertical scale with the SCALE knob so that the entire amplitude of the waveform is displayed
within the waveform display area, and check the input voltage level.
French
Au moment de brancher l'appareil à mesurer sur l'instrument, veiller à ce que l'appareil soit
hors tension. Il est extrêmement dangereux de brancher ou de débrancher des câbles lorsque
l'appareil à mesurer est sous tension.
