Model DMM6500 6½-Digit Multimeter with Scanning Calibration and Adjustment Manual
Section 2: Performance verification
DMM6500-905-01 Rev. A/July 2018
2-31
Use the values in the following tables to verify the performance of the DMM6500. Actual values
depend on the published specifications (see
Example reading limit calculation
(on page 2-4)).
To verify AC current accuracy:
1.
On the DMM6500, 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 verification
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.
7.
Connect the DMM6500 to the calibrator as shown in the following figure.
Figure 15: Connections for AC current verification
8.
Source AC current for each of the frequencies listed in the following tables.
For each setting, make sure that the reading is within low and high limits.
