Selecting the Probe Attenuation or Current-to-Voltage Conversion Ratio
You can select the probe attenuation or current-to-voltage conversion ratio for each
voltage/current input channel.
• You can select the attenuation of the voltage probes of the voltage input channels
(CH1, CH3, and CH5 (CH5 is available only on the DL7480)).
1:1, 10:1, 100:1, or 1000:1
• You can select the current-to-voltage conversion ratio of the current probes of the
current input channels (CH2, CH4, and CH6 (CH6 is available only on the DL7480)).
10A:1V or 100A:1V
*
The conversion notation of the YOKOGAWA 700937 Current Probe is 0.1 V/A. This indicates
that the output voltage of the current probe is 1 V when the current probe measures 10 A.
If you connect the 700937 Current Probe to the signal input terminal of the DL7400 and select a
current-to-voltage conversion ratio of 10A:1V, the DL7400 displays the current value measured
on the current probe as 10 A when the output voltage from the current probe is 1 V.
Waveform Computation (Enabling Power Analysis Parameters to Be Assigned to
Computed Waveforms)
You can select whether to assign power analysis parameters to computed waveform
Math1 or Math2.
OFF
Standard waveform computation parameters can be assigned to the computed waveform.
ON
Power analysis parameters can be assigned to the computed waveform.
