2.1 Sensitivity The setting of the sensitivity calls the electronics to a value of frequency deviation which a vehicle must produce for setting the output of the detector. The sensitivity can be adjusted for each channel in 4 steps with DIP-switches on top of the front panel.sensitivity levelchannel 1: DIP-Switch 1 and 2 channel 2: DIP-Switch 3 and 41 low(0,64% ∆f/f)2(0,16% ∆f/f)3(0,04% ∆f/f)4 high(0,01% ∆f/f)2.2 Frequency adjustment The operation frequency of the detector can be adjusted in two steps with DIP-switch 5.frequencyDIP-Switch 5lowhighThe permissible frequency range is 30kHz to 130kHz. The frequency depends on the loop inductivity (depending itself on: loop geometry, number of loop turns and loop lead) and the adjusted frequency step.
