2.10 Connecting Probes
• 720254 (4CH 1M16)
Maximum input voltage (at a frequency of 1 kHz or less)
• In combination with an safety probe (10:1) 700929 or (100:1) 701947 or a wide
temperature range type (10:1) 7029021
600 V (DC + ACpeak)
• In combination with a safety cable (1:1) (701954)
3
200 V (DC + ACpeak) (as a value that meets the safety standard)
400 V (DC + ACpeak) (maximum allowable voltage, as a value that does not damage
the instrument when applied)
• Direct input (cable that does not comply with the safety standards)
5
42 V (DC + ACpeak)
Maximum rated voltage to ground (at a frequency of 1 kHz or less)
• In combination with an safety probe (10:1) 700929 or (100:1) 701947 or a wide
temperature range type (10:1) 7029022, or a safety cable (1:1) (701954)

400 Vrms (measurement category Other (O))
300 Vrms (CAT II)
Depending on the frequency of the signal applied to the L input and the measurement
category, the maximum rated voltage to ground of the L input of the safety probe and
safety cable is as shown in the following graph.
