Connecting Measurement Leads
Connecting Measurement Leads
When you measure voltage using the 701261 (UNIVERSAL), 701262 (UNIVERSAL
(AAF)), 701267 (HV (with RMS)), or 701265 (TEMP/HPV), connect the measurement
leads of a plug-in type terminal to the input terminal.
H (red)
L (black)
For the 701261, 701262, and 701265
For the 701267
WARNING
• When connecting the item to be measured, be sure to turn OFF the power to the
item. Connecting or disconnecting the measurement lead while the item being
measured is turned ON is very dangerous.
• 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 electric shock, make sure to use the measurement lead suitable for
the voltage range being measured on the input terminals of the 701261
(UNIVERSAL), 701262 (UNIVERSAL (AAF)), 701267 (HV (with RMS)), or
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)
