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.
   
Over-range indication
Indicates the number of the channel that over-range is occurring on.
Channel indication when over-range is occurring on multiple channels
Indicates the smallest number among the channels that over-range is

 AVERTISSEMENT
•  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.
