Table 3-5 Allowable Measurement Ranging Modes
If you choose sweep measurement or sampling measurement (initial interval ³ 2 ms)
and you do not set a ranging mode, auto ranging is set for voltage measurement
mode channel and limited auto (1nA) ranging is set for current measurement mode
channel automatically.
For sampling measurement (initial interval < 2 ms) , an error occurs if fixed range is
not set.
