Range key
Each time pressing range up/down keys, the current range switches.
Choose from three current ranges: 0.5 A, 5 A , 30 A. The indicator for
the selected range lights up.
Output terminal
This terminal outputs measured current waveforms at a certain rate.
Connect it to the BNC input terminal of a oscilloscope. Depending on
the current range selected, the output rate varies between 10 V/A (0.5
A range), 1 V/A (5 A range), and 0.1 V/A (30 A range).
Power plug
This plug is connected to a power terminal of a oscilloscope with
probe power supply or to a power supply receptacle of a power supply
unit (model 701934, sold separately) in order to supply power to
702915/702916.
Overload
When a current (DC and 45 to 66 Hz sine wave) exceeding the
following level specified for each current range is detected, the
overload indicator blinks rapidly.
30 A range:
32.5 ±2.5 Arms
5 A range:
5.25 ±0.25 Arms
0.5 A range:
0.525 ±0.025 Arms
The sampling frequency for overload detection is 7.8125 kHz (typical),
and the checking cycle is 500 ms (typical).
