2.10 Connecting Probes
• Please note that if the circuit being measured is directly connected to the instrument without the use
of a probe, correct measurements may not be possible because of the effect of the input impedance
of the instrument.
• Note that if you use a voltage probe other than an safety probe (700929, 701947, 702902), correct
measurements cannot be displayed when the attenuation is not 1:1, 10:1, 100:1, or 1000:1.
• Follow the instructions given in section 2.2, “Configuring Voltage Measurements,” in the user’s
manual to set the probe attenuation or the current-to-voltage conversion ratio to match the actual
value using the setup menu. If they do not match, measured values cannot be read correctly.
Connecting Current Probes
When using current probes made by YOKOGAWA,* use the probe power supply (701934), sold
separately.
* YOKOGAWA current probes: 701930, 701931, 701932, 701933, 701917, 701918
For details on the connection procedure, see the user’s manual that came with the current probe.

Connecting Clamp-on Probes
YOKOGAWA clamp-on probes 720930 and 720931 can be connected.
For details on the connection procedure, see the user’s manual that came with the clamp-on probe.
