The On-line Indicators When lit, these indicate that the Chart software has located and initialized the Quad Tc/mV Amp. If the light does not go on when the software is run, check that the Quad Tc/mV Amp is properly connected.
The Back Panel The back panel of the Quad Tc/mV Amp is shown in Figure 2–2. The Signal Outputs The Quad Tc/mV Amp provides four signals, one for each sensing thermocouple. These signals are accessed on the Quad Tc/mV Amp back panel via four BNC connectors labelled Channel 1 —...

• If you have tried the above suggestions and still cannot get the Quad Tc/mV Amp to work properly, then try using it on another e-corder if you have access to one. If the on-line indicators still fail to light on the second e-corder, the Quad Tc/mV Amp unit may be faulty and should be returned for repair.
