To specify the channel units
1 Press the probe's associated channel key.
2 In the Channel Menu, press Probe .
3 In the Channel Probe Menu, press Units ; then, select:
• Volts — for a voltage probe.
• Amps — for a current probe.
Channel sensitivity, trigger level, measurement results, and math functions will
reflect the measurement units you have selected.
To specify the probe attenuation
The probe attenuation factor must be set properly for accurate measurement
results.
To set the probe attenuation factor:
1 Press the channel key.
2 Press the Probe softkey until you have selected how you want to specify the
attenuation factor, choosing either Ratio or Decibels .
3 Turn the Entry knob to set the attenuation factor for the connected probe.
When measuring voltage values, the attenuation factor can be set from 0.001:1 to
10000:1 in a 1-2-5 sequence.
When measuring current values with a current probe, the attenuation factor can
be set from 1000 V/A to 0.0001 V/A.
When specifying the attenuation factor in decibels, you can select values from
-60 dB to 80 dB.
If Amps is chosen as the units and a manual attenuation factor is chosen, then the
units as well as the attenuation factor are displayed above the Probe softkey.
