4.4 TUNING
4.4.1 LOOP INDUCTANCE (TUNING) RANGE
The detector will automatically tune to a loop and lead-in combination within the tuning
range of 20 to 2500 microHenry with a Q factor greater than 5.
4.4.2 ENVIRONMENTAL TRACKING
The detector automatically and continuously compensates for component drift and
environmental effects throughout the tuning range and across the entire temperature range.
4.4.3 GROUNDED LOOP OPERATION
Each detector channel will operate when connected to poor quality loops including those
that have a short to ground at a single point.
4.4.4 LEAD-IN LENGTH
The unit will operate with lead-in (feeder) lengths up to 5,000 feet (1,524 m.) with
appropriate loops and proper lead-in cable.
4.5 LOOP INPUT (LIGHTNING PROTECTION)
The loop input incorporates lightning and transient protection devices and the loop
oscillator circuitry is transformer-isolated for each channel. The lightning protection will
