Notes: ① In “Jumper” column, JX means the JX of the measurement is connected in the common use circuitry of
Diagram 6 and Diagram 7.
② In auto mode, it has to press Range key for ACV mode to select ACmv measurement.
③ TSTB=1, the current is input with 400mV/4V; TSTB=0, the current is input with 40mV/400mV. For details,
please refer to “15.13 Current Measurement”.
④ The Mode is to input measuring Hz/Duty with ADP path.
⑤ ADP can input 400.0mV/40.00mV, autoranging, display 4000, 400.0.
