Specifications of the Probe Power Supply Terminals (Optional)
Item
Number of probes that can be used 4
Probes that can be used Current probe (701930, 701931, 701932, and 701933)
Number of current probes that can be used 701930 (150 A): Up to 2
701931 (500 A): Up to 1
701932 (30 A): Up to 2
701933 (30 A): Up to 2
Supply voltage ±12 V, four outputs (up to 1 A total current)
* Up to four 700937 current probes can be used, but this probe is a discontinued product.
When using the current probe, the number of probes that can be used is limited by the current
generated by the device under measurement (current measured by the current probe). The measured
versus consumed current characteristics of current probes that can be connected to the instrument are
indicated below.
