Connecting Probes
Connecting Probes
Connect the probes (or other input cables such as BNC cables) to any of the input
terminals of the modules below. The input impedance is 1 M
Ω
±
1% and approximately
35 pF in parallel.
• High-Speed 10 MS/s, 12-Bit Isolation Module:
701250 (HS10M12)
• High-Speed High-Resolution 1 MS/s, 16-Bit Isolation Module: 701251 (HS1M16)
• High-Speed 10 MS/s, 12-Bit Non-Isolation Module:
701255 (NONISO_10M12)
• Acceleration/Voltage Module (with AAF):
701275 (ACCL/VOLT)
• Frequency Module:
701280 (FREQ)
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.
Precautions to Be Taken When Using the Modules
• Do not apply input voltage exceeding the maximum input voltage, withstand
voltage, or allowable surge voltage.
• To prevent electric shock, be sure to furnish protective earth grounding of the SL1400.
• To prevent electric shock, be sure to fasten the module screws. Otherwise, the
electrical protection function and the mechanical protection function will not be
activated.
• Do not leave the instrument connected to devices in an environment that may
be subject to voltage surges.
• Use only specified cables. Using cables that do not meet the safety
specifications is extremely dangerous (especially when using high voltages
(42 V or higher).
• When measuring high voltages using the 701250 (HS10M12) or the 701251
(HS1M16), use the isolated probe (700929), 1:1 safety cable (combination of
701901 and 701954), or differential probe (700924).
• The BNC part of the passive probe (701940) is made of metal. Therefore, use
the probe at 42 V or less for isolated inputs (701250 (HS10M12), 701251
(HS1M16), 701275 (ACCL, VOLT), and 701280 (FREQ)) for safety reasons. (Do
not connect voltage above 42 V to both the High and Low sides.) For non-
isolated inputs (701255 (NONISO_10M12), etc.), fasten the module screws.
• When measuring high voltage to the 701280 (FREQ), use the isolated probe
(700929).
