Equipment
Requirements Calibrator (item 1)
Dual Banana Connectors, two (item 3)
Coaxial cable, one (item 2)
Prerequisites All prerequisites listed on page A–22
1. Set the Calibrator to 18 0 . 000 mV and 6. 0 kHz.
2. Connect the Calibrator to the VX4234 Voltage input using two Dual-Banana
connectors and a Coaxial cable.
3. Set the VX4234 to AC volts and the 2
00
mV range (Function 5, Range 2).
(Note: There is no Range 1 for AC). Acquire a reading from the VX4234 and
verify the response relative to the limits shown in the Test Record (limits are
also shown in Table 9):
