Wiring System Combination

• If you select 1P3W, 3P3W, 3P4W, or 3P3W(3V3A) for the wiring system, the wiring unit is set with the two or three elements adjacent to the selected element whose element numbers are larger than the selected element.

• On models that have four elements installed, up to two wiring units (ΣA and ΣB) are automatically set. The wiring unit symbols ΣA and ΣB are attached to the element numbers in order, starting with the smallest

number.

IM PX8000-02EN

Note

• Because the wiring system with the largest element number is automatically determined according to the settings of the wiring system with the smallest element number, the element with the largest element number cannot be selected.

• You cannot set the wiring units for larger element numbers before the wiring units for smaller element numbers.

Setting the Voltage Measurement Range (Vertical Scale, RANGE Knob)

This section explains how to set a fixed range. (If Auto Range in the U menu is set to ON, the measurement range changes depending on the amplitude of the input signal.)

Turn the RANGE knob to set the voltage measurement range.

• Select from 1.5V, 3V, 6V, 10V, 15V, 30V, 60V, 100V, 150V, 300V, 600V, and 1000V.

• Auto Range in the U menu is set to OFF.

• If you turn the RANGE knob when waveform acquisition is stopped, two values are shown on the measurement range screen. The upper value is the measurement range for the displayed waveforms. The lower value is the measurement range that you have specified. The new range will be applied the next time waveform acquisition is started.

• If you do not operate the RANGE knob for approximately 3 seconds, the measurement range that you are setting with the knob will disappear from the screen.

CAUTION

If the input coupling is AC, in accordance with the frequency response, the input signal is attenuated more in lower frequencies. As a result, even when a high voltage signal is actually applied, it may not be measured as a high voltage signal. Furthermore, the PEAK OVER message may not be displayed on the screen. As necessary, switch the input coupling to DC to check the input signal voltage. Applying an input signal whose voltage exceeds the maximum input voltage of the AUX module may damage the input section.

ATTENTION

Si le courant du couplage d’entrée est alternatif (CA), conforme à la réponse en fréquence, le signal d’entrée est davantage atténué aux fréquences plus basses. Par conséquent, même si vous appliquez un signal de tension élevée, ce dernier risque de ne pas être mesuré comme tel. De plus, le message de dépassement de plage (PEAK OVER) risque de ne pas s’afficher à l’écran. Le cas échéant, basculez le couplage d’entrée sur CC (courant continu) afin de vérifier la tension du signal d’entrée. Si la tension du signal d’entrée dépasse la tension d’entrée maximale du module AUX, la section d’entrée risque d’être endommagée.

Setting the Probe Attenuation (Probe)

1:1, 10:1, 100:1, 1000:1: Displays the voltage probe attenuation

Note

If the probe attenuation is not set correctly, the input signal voltage will not be displayed correctly. For

example, if you use a 10:1 voltage probe but set the probe type to 1:1, the automatically measured amplitude
