Cardinal Scale’s NEST provides fast, accurate, and ultra-portable truck scale diagnostics. Quickly view individual load cell readings and check the home run and weight indicator connections. NEST plugs directly into the trim board of a Cardinal truck scale universal section seal trim box and displays millivolts and pounds readings for up to 12 load cells and the reading from the junction box summing circuitry. Unique to the weighing industry, NEST provides a service technician the toolkit to see where a scale’s potential issues may exist within seconds. There are three display modes: signals display, minimum-maximum display, and signals minus zero.
