FREQUENTLY ASKED QUESTIONS

Technical Specifications:

Q: What A/D resolution is used by the NR-TH08 measurement unit?

A: The NR-TH08 uses a high-accuracy 24 bit delta-sigma A/D conversion system.

Wiring & Installation:

Q: What are the input specifications for the TRG IN synchronization control terminal on the NR-500?

A: TRG IN requires a voltage input of 10 to 30 VDC with a minimum pulse duration of 2 ms.

Troubleshooting & Compatibility:

Q: What is the synchronization time accuracy between multiple measurement units connected to the NR-500?

A: The synchronization accuracy between connected measurement units is typically plus/minus 1 microsecond or less.

Replacement & Upgrades:

Q: What is the primary difference between the NR-TH08 and the NR-TH08P measurement units?

A: The NR-TH08P model uses miniature thermocouple connectors instead of screw terminals for input.
