This field specifies the channel set by this dialog box.
Current Auto Ranging Current measurement auto range operation, NORMAL,
SPEED, or RESOLUTION (RESOLN). See
Table 4-6 .
Voltage Auto Ranging Voltage measurement auto range operation, NORMAL,

Table 4-6 Measurement Auto Range Operation
• Basic operation
The channel automatically sets the range which provides the best resolution in
performing the measurement.
• Upward changing operation
If measured data

value1 , the range changes up after the measurement.
value1 = measurement range

rate / 100
• Downward changing operation
If measured data

value2 , the range changes down immediately.
value2 = measurement range

rate / 1000
Description
NORMAL Supports basic operation and downward changing operation
