2.10 Connecting Probes
Connecting Probes
Connect the probes (or other input cables such as BNC cables) to any of the input terminals of the
following modules. The input impedance is 1 MΩ ± 1 % and approximately 35 pF.
• High-Speed 100 MS/s, 12-Bit Isolation Module: 720211 (HS100M12)
• High-Speed 10 MS/s, 12-Bit Isolation Module: 720250 (HS10M12)
• 4-CH 1 MS/s, 16-Bit Isolation Module: 720254 (4CH 1M16)
• Acceleration/Voltage Module (with AAF): 701275 (ACCL/VOLT)
• Frequency Module: 720281 (FREQ)
• SENT Monitor Module: 720243 (SENT)
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.
Precautions to Be Taken When Using the Modules
• Do not apply voltage exceeding the maximum input voltage or maximum rated voltage to
ground.
L
• To prevent the possibility of electric shock, be sure to fasten the module screws. Otherwise,
the electrical and mechanical protection functions will not be activated.
• Avoid continuous connection under an environment in which the surge voltage may occur.
• Use only specified cables. It is extremely dangerous to use cables that do not meet the
safety standards. (Especially when you are handling high voltages of 42 V or more.)
• To measure high voltage with the 720211 (HS100M12), 720250 (HS10M12), or 720254 (4CH
1M16), use the safety probes (700929, 701947, 702902) or 1:1 safety cables (combination
of 701901 and 701954).
