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
• Toujours mettre l'appareil à mesurer hors tension avant de le brancher sur l'instrument. Il
est extrêmement dangereux de brancher un câble de mesure lorsque l'appareil à mesurer
est sous tension.
• Lors de la mesure de tension élevées, ne pas relier une borne de type enfichable, avec
des parties conductrices exposées, à la borne d'entrée à utiliser comme un fil de mesure. Il
est très dangereux que le connecteur se détache.
