Number of current probes that can
be used
701930 (150 A): 3
701931 (500 A): 2
701932 (30 A): 3
701933 (30 A): 3

Supplied voltage
±12 V 2 outputs (up to a total of 1300 mA)
When using current probes, the number of probes that can be used is limited by
the current that runs through the device under measurement (current measured by
the current probe). The characteristics of the measured current versus the current
consumption of a current probe that can be connected to the SL1000 are shown below.
