AC current verification
The following topics describe how to verify ac current.
Verify ac current on the 100 µA to 3 A ranges
To verify ac current accuracy, you will:
•
Apply accurate voltages from the Fluke 5720A or 5730A multifunction calibrator to the DAQ6510
front-panel terminals.
•
Verify that the displayed readings fall within specified limits.
Use the values in the following tables to verify the performance of the DAQ6510. Actual values
depend on the published specifications (see
Example reading limit calculation
(on page 2-4)).
To verify ac current accuracy:
1. On the DAQ6510, press the
FUNCTION
key and select
AC Current
.
2. Press the
HOME
key.
3. Set the range you are verifying.
4. Press the
MENU
key.
5. Under Measure, select
Settings
.
6. Make sure that Detector Bandwidth is set to
30 Hz
.
AC current is specified for the detector bandwidth setting of 3 Hz. 3 Hz measures accurately for input
signals from 3 Hz to 10 kHz, with reading rates of ≈ 0.5 readings/s. To improve v
erification
throughput to ≈ 3.3 readings/s, set detector bandwidth to 30 Hz for frequencies of 30 Hz to 10 kHz.
To verify frequencies 1 kHz and higher, set the detector bandwidth to 300 Hz for faster ≈ 55
readings/s throughput.
