Connecting Differential Probes (700924)
When using differential probes (700924) made by YOKOGAWA, connect the BNC output
connector to the input terminal of the oscilloscope. In addition, be sure to connect the
GND lead to the functional ground terminal of the SL1400. If necessary, use the auxiliary
grounding lead extension. A measurement of 1400 Vpeak is possible by connecting the
GND lead to the SL1400.
For details on the connection procedure, see the manual that comes with the differential
probe.

WARNING
Precautions to Be Taken When Using High Voltage Differential Probes
Be sure to connect the GND lead of the differential probe (700924/700925) to the
functional ground terminal on the right side panel of the SL1400. Otherwise, high
voltage may appear at the BNC connector making it dangerous. Be sure to connect
the GND lead to the SL1400 before connecting the probe to the parameter to be
measured.
