Input DC voltage *4±VDC
Input DC current
Insurance **0V,1A(delay type)
Center frequency 8.2±0.*5MHz
Scan frequency deviation ±**0KHz
Modulation frequency **0, **0, **0, **0Hz
2. Setting and debugging of T*4 transmitter
1) There are 4 routes of modulation signals of **0, **0, **0, **0Hz on the panel of T*4 transmitter, which can be selected for using, especially when EAS equipment multi-point installation is difficult for online connection, so as to avoid the interference between EAS equipment. The **0Hz modulation signal has the priority for selection. If to change the modulation signal on the panel of transmitter, it needs to regulate the frequency sweep range at the same time; its method is as following item.
2) Frequency sweep range
Put EAS tester vertically on the top of transmitter case, press EAS tester power switch, and adjust R*4 to let of EAS: displaying ***0±*0KHz. If no EAS tester, use oscillograph for adjustment, firstly disconnects the P5 terminal antenna on transmitter panel, set the JP1 on 1&2. Connect the probe of oscillograph to the transmitter TP4, earth to TP2, adjust the potentiometer R*4, making the level at TP4 point is 0.7Vp-p sine wave, then re-connect the P5 terminal antenna properly, set JP1 on 2&3.
3) Radio frequency output amplitude: adjustment of radio frequency output amplitude relates to the testing gate distance. Connect the probe of oscillograph to TP7, earth to TP8. Adjust R*3 can change the amplitude of radio frequency output, and TP7 point is the sine wave of ****0 Vp-p.
4) Center frequency adjustment: Connect the probe of frequency recorder to TP6, earthing to TP8. Adjust R*5 potentiometer to 8.2±0.*5MHz.
3. Operating several transmitter without online connection (stagger frequency)
If there are 2 sets (or more) of testers being used on a same field, and their online connection is difficult, by changing the transmitter’s modulation frequency **0, **0, **0 and **0Hz, to let each transmitter have different modulation frequency, so as to avoid interference with each other.
For detailed application, it needs to consider the real situation on the field, and keep following principles:
If there are 2 sets (or more) of testers being used without online connection, the distance between them shall be greater than *0M.
