2.12 Connecting Measurement Leads
• 701261, 701262, 701265, 720266
Maximum input voltage (across the input terminals, H and L,
1
at a frequency of 1 kHz or
less)
42 V (DC + ACpeak)
Maximum rated voltage to ground (across the input terminals, H or L, and earth,
2
at a
frequency of 1 kHz or less)
42 V (DC + ACpeak) (CAT II, 30 Vrms)
• 720268 (HV (AAF, RMS))
Maximum input voltage (at a frequency of 1 kHz or less)
• Combination of measurement lead 758933 and alligator clip 701954 or the combination
of 1:1 safety adapter lead 701904 and alligator clip 701954
3
1000 Vrms (1000 VDC or 1414 Vpeak MAX)
• 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)
• Combination of measurement lead 758933 and alligator clip 701954
4
or the combination
of 1:1 safety adapter lead 701904 and alligator clip 701954

1000 Vrms (CAT II),
7
600 Vrms (CAT III)

7 When a signal with large amplitude is applied to the L input, depending on the
number of input channels, the input signal frequency, and the measurement category,
the maximum rated voltage to ground of the L input of the measurement lead or
safety adapter lead is as shown in the following graph.
