3.7 Connecting Measurement Leads
Connecting Measurement Leads
When you measure voltage using the 701261 (UNIVERSAL), 701262 (UNIVERSAL (AAF)),
701267 (HV (with RMS)), and 701265 (TEMP/HPV), connect the measurement leads of a plug-in type
terminal to the input terminal.

WARNING
• When connecting a device under measurement to the instrument, be sure to turn off the
device. It is extremely dangerous to connect or remove measurement leads while the
device under measurement is on.
• When measuring high voltages, do not connect a plug-in type terminal with exposed
conducting parts to the input terminal to be used as a measurement lead. It is very
dangerous, if the connector comes loose.
Precautions to Be Taken When Using the Modules
• To prevent the possibility of electric shock, always connect measurement leads that
match the voltage range that you are measuring to the signal input terminals of the
701261 (UNIVERSAL), 701262 (UNIVERSAL (AAF)), 701267 (HV (with RMS)), and
701265 (TEMP/HPV).
• When measuring high voltages using the 701267 (HV (with RMS)), use a measurement
lead 758933 and alligator clip 701954.
Maximum Input Voltages and Maximum Allowable Common Mode Voltages for the Modules
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.
• For the 701261, 701262, and 701265
Maximum input voltage (across the input terminals, H and L,
1
at a frequency of 1 kHz or less)
42 V (DC+ACpeak)
Maximum allowable common
mode voltage (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)
3-30
