Chapter 4 Calibration Procedures Relay Verification (Optional) Test 1: 34908A Relay Contact Resistance Verification This optional procedure uses an external DMM to make 4-wire ohms measurements across the relay contacts on the 34908A. Note that when measuring the resistance of the contacts of the channels relays, the test also includes the Bank Switch. Note: Be sure to read “Plug-in Module Test Considerations” on page 97. See the diagram on page 117 for the required connections for this test (be sure to probe the inductor at the indicated location). For this measurement, the 34908A is not installed in the 34970A/34972A. Record the 4-wire ohms measurements from the external DMM in the table below. External DMM Ohmmeter Connections Test # HI LO HI Sense LO Sense Measured Value 1 L400 J101, C12 L400 J101, C12 _____________ Ohms 116
