Ranging Mode
Auto Ranging
Range changing is performed as below.
For measurement
channels
The measurement channel automatically searches for and measures at the range that
provides the best resolution as follows:
• For current measurement, the measurement channel uses the present range if the
following formula is satisfied; otherwise, the channel changes the range.
Range × 0.1 ≤ Measurement value ≤ Range × X/100
where X=115, or 100 at the maximum range.
See also “Enhanced Auto Ranging for Current Measurement” on page 6-8.
• For voltage measurement, the measurement channel uses the present range if the
following formula is satisfied; otherwise, the channel changes the range.
Next lower range value ≤ Measurement value ≤ Range × X/100
where X=110, or 100 at the maximum range.
For output
channels
The output channel automatically searches for and forces at the lowest range that
covers the output value as follows:
• For staircase sweep output, the output channel uses the lowest range that covers
the start and stop values. However, it uses the lowest range that covers the step
output value for the logarithmic current sweep. For the voltage sweep that sets
the power compliance, the channel uses the lowest range (20 V range or more)
that covers the step output value.
• For pulsed bias output, the output channel uses the lowest range that covers the
base and peak values.
• For pulsed sweep output, the output channel uses the lowest range that covers
the base, start, and stop values.
• For quasi-pulsed output and search source output, the output channel uses the
lowest range that covers the start and stop values.
The maximum output value is as follows:
• Maximum current output value = Range × X/100
where X=115, or 100 at the maximum range.
• Maximum voltage output value = Range value
