YOKOGAWA DL850 ScopeCorder User Manual

Precautions to Be Taken When Using Current Probes
When connecting the current probe to the probe power supply terminal on the right side panel,
make sure that the current does not exceed the range shown below. Otherwise, the DL850/DL850V
operation may become unstable due to the activation of the excessive current protection circuit of the
power supply.
(Total current consumption for A through D) ≤ 1 A

Number of probes that can be used 4
Probes that can be used Current probe (700937, 701930, 701931, and 701933)
Number of current probes that can be used 700937 (15 A): Up to 4
701930 (150 A): Up to 2
701931 (500 A): Up to 1
701933 (30 A): Up to 2
Supply voltage ±12 V, two outputs (up to 1 A total current)
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.
