What is the Correct AC Coupling Test for the 720210 Analog Voltage Input Module?

The correct AC coupling test for the 720210 Analog Voltage input module must be performed at 20 Hz.
The service manual, SMDL850-01EN_010 1st Ed, suggests that you perform the AC COUPLING test at 15 Hz. This is a typo and incorrect, the test must be performed at 20 Hz.

Additional Information
  • Confirmation: The QIS720210-E_010 has the correct procedure outline for the AC COUPLING TEST at 20Hz.
  • Confirmation: Yokogawa Corp of America Cal Lab using Intercal METCAL script performs this test at 20 Hz.
