1. Press one of the CH1 to CH8/4 keys to select the channel. The CH menu
appears.
You can select up to channel CH4 and CH8 on the DL7440 and DL7480, respectively.
2. Press the Probe soft key. The Probe menu appears.
3. Press the soft key corresponding to the desired attenuation/current-to-voltage
conversion ratio.
You can select the attenuation or the current-to-voltage conversion ratio of the probe of
each channel according to the probe being used from the following.
1:1, 10:1, 100:1, 1000:1, 10 A:1 V (0.1 V/A), or 100 A:1 V (0.01 V/A)
• 1:1 to 1000:1 are probe attenuation settings.
• 10 A:1 V (0.1 V/A) and 100 A:1 V (0.01 V/A) are probe current-to-voltage
conversion ratio settings. The model name of the supported current probe is
indicated inside the parentheses.
Note
If the attenuation or the current-to-voltage conversion ratio is not set correctly, the voltage and
scale values of the input signals will not be displayed correctly. For example, if you set the
attenuation to 1:1 when you are actually using a 10:1 probe, the displayed value for the
waveform amplitude will be 1/10th the actual value.
