Test 4-3: AC Voltage Test
This test verifies AC voltage accuracy on the 87.5 mV and 300 V ranges
using sine wave inputs at
≥
50% of full scale. The input frequency varies
from 20 Hz to 10 kHz. The DC component must be <10% of the AC
component.
NOTE
The DC Voltage Performance test must be performed prior to the AC
Voltage test to check the A/D accuracy on all ranges. If the DC Voltage test
has not been performed, the AC voltage must be checked on all ranges.
Equipment Setup
1.
Connect the equipment as shown in Figure 4-3.
WARNING
The AC Standard (Datron 4708, Option 20) can produce
dangerous voltages which are present on the terminals. Do not
touch the front (or rear) panel terminals unless you are sure no
dangerous voltage is present.
