Verification Tests
Performance Verification
Optional AC Voltage Gain Verification
These tests are NOT intended to be performed with every calibration. This
procedure is used to verify additional instrument AC voltage specifications.
Connect the AC Standard across the multimeter’s HI and LO input terminals as
shown in Figure 4-5.
1
Set up the multimeter as follows:
Reset multimeter
*RST
Configure for AC voltage
CONF:VOLT:AC
Select Slow AC filter
DET:BAND 3
2
Set the AC Standard controls as follows:
Output
1 V
Frequency
20 Hz
3
Set the multimeter to the 100 mV range using the following command:
Set range
VOLT:RANG .1
4
Perform the measurement using the READ? command.
5
Verify the result is within specified limits and record the result.
6
Change amplitude range using VOLT:AC:RANG <range> and make a
measurement for each ACV input and range shown in Table 4-6 verifying the
result is within specified limits. Record the result.
