Settling Characteristics
For first reading or range change error using default delays, add .01% of input step additional error for the 100
µA to 100 mA ranges. For the 1 A range add .05% of input step additional error.
The following data applies for DELAY 0.

1. The source of frequency
measurements and the
measurement input
coupling are determined by
the FSOURCE command.
2. Range dependent, see ACI
for specific range
impedance values.
3. Gate Time is determined
by the specified
measurement resolution.
4. For Maximum Input
specified to fixed range
operation. For auto range,
the maximum speed is 30
readings/sec for ACBAND
³ 1 kHz.
Actual Reading Speed is
the longer of 1 period of
the input, the chosen gate
time, or the default reading
time-out of
1.2 sec.
