Ac Current - Fluke 8588A Operator's Manual

AC Current

The AC Current function provides measurements that use the INPUT A and LO
Input terminals. Push  to put the Product into the AC Current (ACI)
function. The AC Current function features 8 ranges (10 μA to 30 A) for the
8588A and 6 ranges (10 μA to 1 A) for the 8558A. The 10 µA, 100 µA, 1 mA,
10 mA, 100 mA and 10 A, ranges provide 202 % overrange. For example, the
10 A range displays up to 20.2 A. The 30 A range measures up to 30.2 A.
The 10 A and 30 A ranges are not available on the rear inputs.
Resolution can be set from 7 1/2 digits to 4 1/2 digits. The default is 6 1/2 digits
of resolution.
The Product uses a proprietary sampling method to make true-rms ac current
measurements.
ACI Menu
The available ACI menu softkeys are explained below:
 (Range): Each of the ranges can be selected or the Product can be put
into autorange by selecting Auto. Make the range selection with the softkeys or
use the navigational keys to highlight the selection and push .
 (Resolution): ACI has resolution from 4 1/2 digits to 7 1/2 digits. The
default is 6 1/2 digits. Make the resolution selection with the softkeys or use the
navigational keys to highlight the selection and push .
ACI, unlike ACV, has no Band selection. The Product uses the
wideband setting for all ACI measurements, measuring signals up to
100 kHz.
 (RMS Filter): Provides selection of various filters for the rms converter.
These filters allow measurements to be made down to the chosen filter frequency
without degradation of accuracy and excessive reading variation. One of these
filters is always in the circuit. The 40 Hz filter is the default selection at power on.
The filter choices available are 0.1 Hz, 1 Hz, 10 Hz, 40 Hz, 100 Hz and 1 kHz.
Make the selection with the softkeys or use the navigational keys to highlight the
selection and push . The filter setting determines the reading rate in ACI.
See the specifications for the AC filter settings and reading rates. See
