The Nortech DU100 Diagnostic Unit is a hand held test instrument capable of providing installation/service personnel with positive verification of the correct operation of a vehicle detector installation. It may only be utilised in conjunction with Nortech inductive loop detectors, which have integral diagnostic capability. Current operational and historical data are transferred from the vehicle detector to the DU100 by means of an optical link. Data transmission form the vehicle detector limit occurs continuously so no service disruption is necessary. Received data is verified for integrity by means of a cyclic redundancy check (CRC) processes, and then displayed on the LCD screen.
The DU100 Diagnostic Unit is indispensable for:
- Setting detector sensitivity
- Performance checks on loops and installation
- Checking intermittent failures through the historical data
- Eliminating any detector crosstalk
Key Features
- Compact, self-contained unit
- Exclusive optical readout
- No service disruptions
- Loop diagnostics
- Historical data available
