Product Q&A
- Q: Can the 3500/42M monitor different transducer types simultaneously?
- A: Yes, it accepts inputs from proximity probes, seismic velocity sensors, and accelerometers.
- Q: What is the primary difference between the 42M and the 40M?
- A: The 3500/42M provides individual 4-20 mA recorder outputs for each channel, whereas the 40M does not.
- Q: How are alarm setpoints configured?
- A: Alarms and monitoring functions are configured via the 3500 Rack Configuration Software.
