3.7 Connecting Measuring Leads
Connecting Measuring leads
If measuring the voltage on the 701261 (UNIVERSAL), 701262 (UNIVERSAL (AAF)),
701267 (HV (with RMS)), 720268 (HV (AAF, RMS)), 701265 (TEMP/HPV), or 720266
(TEMP/HPV), connect the measuring leads of a bipolar banana plug terminal to the input
terminal (binding post terminal) as shown below.

WARNING
• When connecting an item to be measured to the SL1000, be sure to turn OFF
the power to the item. Connecting or disconnecting the measuring lead while the
item being measured is turned ON is very dangerous.
• Do not connect a plug-in type terminal with exposed conducting parts to the
input terminal to be used as a measuring lead. It is very dangerous, if the
connector comes loose.
• If a measuring lead comes loose from a module’s connector, do not touch the
measuring lead terminal. Doing so can cause electric shock. If a measuring lead
comes loose, turn OFF the device under measurement.
Using the Module
• To prevent electric shock, make sure to use a measuring lead suitable for
the voltage range being measured on the input terminals of the 701261
(UNIVERSAL), 701262 (UNIVERSAL (AAF)), 701265 (TEMP/HPV) or 720266
(TEMP/HPV).
• If you are measuring high voltages using the 701267 (HV (with RMS)) or
720268 (HV (AAF, RMS)), use a measurement lead(combination of 758933 and
701954) or 1:1 safety cables (combination of 701904 and 701954).
Maximum Input Voltage and Maximum rated voltage to earth
Applying a voltage exceeding the value indicated below may damage the input
section. If the frequency is above 1 kHz, the input section may be damaged even if
the voltage is less than the indicated values.
• For the 701261, 701262, 701265 and 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 earth (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)
