Sensors and Signal Output Sources That Can Be Connected
The table below shows the sensor and signal output source that can be connected. Appropriate input
presets are provided for each sensor and signal output source. For information on how to set presets,
see “Input Settings (Input Setup)” in section 2.8, “Configuring Frequency, Revolution, Period, Duty
Cycle, Power Supply Frequency, Pulse Width, Pulse Integration, and Velocity Measurements,” in the
user’s manual.

* For the internal equivalent circuit when the preset setting is Pull-up 5V, see the “Frequency Measurement”
section in chapter 4, “Vertical Axis” in the feature’s guide (IM DL350-01EN).
WARNING
If over-range is indicated, the instrument may be receiving a voltage higher than the observed
waveform or measured waveform values. To prevent electric shock, change the vertical scale
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 occurring on

AVERTISSEMENT
En cas de dépassement de plage, l’instrument risque de recevoir une tension supérieure à la
forme d’onde observée ou aux valeurs de forme d’onde mesurées. Pour éviter tout risque de
choc électrique, modifier l’échelle de gain vertical de sorte que l’amplitude entière de la forme
d’onde s’affiche sur l’afficheur, et vérifier le niveau de tension d’entrée.
Dépassement de plage
Indique le numéro de canal sur lequel le dépassement de plage a lieu.
L’indication du canal en cas de dépassement de plage sur des canaux multiples
Indique le numéro le plus petit parmi les canaux sur lequel le dépassement a lieu.
