DMM6500 6½-Digit Multimeter with Scanning Calibration and Adjustment Manual
To verify ac voltage accuracy:
1. Connect the DMM6500 HI and LO INPUT connectors to the calibrator as shown in the following
figure.
2. On the DMM6500, press the FUNCTION key and select AC voltage.
3. On the home screen, select the button next to Range and select 100 mV.
4. Press the MENU key.
5. Under Measure, select Settings.
6. Make sure that detector bandwidth is set to 30 Hz.
AC voltage is specified for the detector bandwidth setting of 3 Hz. Three Hz measures accurately for
input signals from 3 Hz to 300 kHz, with reading rates ≈ 2 readings/s. To improve verification
throughput to ≈ 20 readings/s, set detector bandwidth to 30 Hz for frequencies of 30 Hz to 300 kHz.
To verify frequencies 1 kHz and higher, set the detector bandwidth to 300 Hz for faster ≈ 200
readings/s throughput.
7. Source ac voltages for each of the frequencies listed in the
(on page 2-12) table.
8. Repeat these steps for each range and frequency listed in the tables below. For each voltage
setting, be sure that the reading is within low and high limits.
