2.12 Connecting Measurement Leads
Connecting Measurement Leads
When you measure voltage using the 701261 (UNIVERSAL), 701262 (UNIVERSAL (AAF)), 720268
(HV (AAF, RMS)), 701265 (TEMP/HPV), or 720266 (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)), 720268 (HV (AAF, RMS)), 701265 (TEMP/
HPV), or 720266 (TEMP/HPV).
• When measuring high voltages using the 720268 (HV (AAF, RMS)), use a 1:1 safety
adapter lead 701904 or measurement lead 758933 and alligator clip 701954.
