• The BNC part of the Passive Probe for the DL750/DL750P (701940) is made
of metal. Therefore, use the probe at 42 V or less for isolated inputs (701250
(HS10M12), 701251 (HS1M16), 701260 (HV (with RMS)), 701275 (ACCL/
VOLT), 701280 (FREQ), etc.) for safety reasons. (Do not connect voltage
above 42 V to both the High and Low sides.) For non-isolated inputs (701255
(NONISO_10M12), etc.), fasten the module screws.
• The measurement category of the 701260 (HV (with RMS)) is 400V-CATII on
the low side and 700V-CATII on the high side. Use caution because the
overvoltage tolerance differs between the low and high sides.
• When applying high voltage to the 701280 (FREQ), use the isolated probe
(700929).
• In Using the 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 DL750/DL750P.
Otherwise, high voltage may appear at the BNC connector making it dangerous.
• Applying a voltage exceeding the value indicated below may damage the input
section. If the frequency is above 1 kHz, damage may occur even when the
voltage is below this value.

• High-Speed 10 MS/s, 12-Bit Non-Isolation Module (701255)
This module is non-isolated. Be sure to fasten the module screws when
measuring a voltage above 42 V on this module. In addition, use the
dedicated non-isolated passive probe (10:1) (701940).
