Specificaio:
Ipu volage: DC5V
Operaig volage: abou 30mA
Trasisor eser corol
The eser is corolled by a roary ecoder swich.
The roary ecoder swich ca have a oal of 6 operaios, shor press, log press, lef ur, righ ur, press lef ur, press righ ur.
Press oce i he off sae o ur o he power ad sar he es.
Afer a es is compleed, if o device is deeced. Log press he swich or roae he swich lef ad righ o eer he fucio meu. Afer eerig he fucio meu, he lef or righ swich ca selec up ad dow he meu iem. To eer a fucio iem, press he swich oce. Whe you eed o exi from a fucio, hold dow he swich.

Feaures:
1. Digial liquid crysal display, easy readig, ca display he measured daa ad graphics
2. Roary swich corol, easy o use buo measureme
3. Log press he es buo o exi he frequecy measureme fucio. The frequecy measureme rage is from 1Hz o above 1MHz. Whe he measured frequecy is lower ha 25KHz, he cycle is displayed
4. Square wavig geeraor, here are muliple levels of squarewavig frequecy opioal, lef or righ roaio es buo o swich differe square wavig frequecy, log press he es buo o exi he squarewavig geeraor
5. Pulse sigal geeraor, lef or righ roaio es buo o adjus pulse duy cycle from 1% o 99%. Log press he es buo o exi he pulse geeraor
6. Use 5V Type-c power supply ierface for power supply, cusomers ca also solder 9V baery ierface for power supply
7. Auomaic shudow, shudow curre is oly abou 20A

Noe:
Before esig he capacior, discharge he capacior firs, ad he iser he es base for measureme, oherwise he microcoroller of he eser may be damaged.

Package icludes:
1x GM328A rasisor eser

Calibraio:
1. Teser calibraio is used o elimiae he error of is ow compoes, so ha he fial es resuls are more accurae. Calibraio is divided io rapid calibraio ad full-fucio calibraio.
2. Operaio mehod of quick calibraio: shor coec he hree es pois TP1, TP2 ad TP3 wih wires, ad he press he es buo, while payig aeio o he scree. The scree color will chage o whie ex o black backgroud, ad he promp "Selfes mode.. ?" Afer ha, press he es buo o eer he rapid calibraio process; If he message "Selfes mode.. ?" Afer ha, if here is o key wihi 2 secods, a ormal es process will be carried ou. Fially, he resisace values of he wires a he hree es pois of TP1, TP2 ad TP3 are displayed. Oce you go hrough he quick calibraio process, you"ll see some daa o he scree, jus igore i. Wai uil a blikig srig appears o he scree"Isolae he Probes!" Afer ha, remove he shor wires of TP1, TP2, ad TP3. The quick calibraio is compleed uil he srig "Tes Ed" appears o he scree. For he firs calibraio, use full fucio calibraio.
3. Full fucio calibraio eeds o be accessed from he fucio meu, ad a addiioal 220f capacior is required. Full-fucio calibraio performs a more comprehesive calibraio process ad akes loger. Oce i he feaures meu, roae he es buo o he meu iem "Selfes", he press he es buo o eer he fully fucioal calibraio process, wih he blikig srig "shor Probes!" poppig up o he scree firs. As wih he quick calibraio, he hree es pois are shored wih wires ad wai for he calibraio process o occur, wih he srig "isolae Probes!" flashig o he scree. , remove he shor i hree es pois lead, coiue o wai for he calibraio process, he scree srig "1 - | | - 3 & g; For 100f, isall he 220f capacior o he es pois TP1 ad TP3. Wai uil he scree promps "Tes Ed" ad he full-fucio calibraio process is complee.
