It is necessary to use it when you debug the antennas.
(Forbid debugging the antennas without EAS tester)
Detection devices frequency and testing environment conditions
Detailed introduction to EAS Tester:
EAS Tester
EAS Antenna tester---EAS system anti shoplifting system
Dimension: 140mm* 70mm* 25mm
GW: 0.4kg (without battery)
Electric tension: DV3v
Power supply: Size AA 1.5V * 2
Small size and light weight make it very portable.
Nice assistant to maintenance personnel.
Make sure the EAS system is under operation. Parallel the tester close to transmitter antenna. Press the START ON button.
You can see the main technical parameters (including the three below) of transmitter board displayed in figure.
1. FC: Center Frequency of transmitter (normal 8200+ / - 50Hz).
Adjusting R15 (resistance potentiometer) to change it.
2. FS: Main Frequency Signal of transmitter (normal 150, 160, 170, 180Hz).
Factory default setting is 180Hz. You need to set this parameter on board if no Sync cord is used, to avoid co-channel Interference.
3. SCAN WIDTH of transmitter (normal 880-1000Hz)
Factory default setting is usually 84 to change this parameter. Change the modulation frequency on transmit 80Hz. Adjust R1ter board, this parameter will change accordingly.
Power off in fixed time: Auto power off in 1 minute if not working.
