Úprava metódy a bezpečnostné opatrenia pred pred použitie použitie the multimeter
1, v the proces of použitie the multimeter, you can not use your hand to touch the metal part of the pen, so that on the one hand, you can ensure the accuracy of the measurement, on the other hand, you can also ensure personal safety.
2,Kedy meranie a určité množstvo z elektrina, vy môžem't zmena prevodový stupeň na the rovnaký čas z meranie, zvlášť kedy meranie vysoké napätie alebo vysoká prúd, vy by ste mali platiť viac pozornosť na to to to, inak multimeter bude bude zničené. ak vy potreba do radenie. Mal by som prvý odpojiť merač pero radenie prevodový stupeň a potom meranie.
3, the multimeter musí be umiestniť horizontálne kedy in use. So as not to cause errors. At the same time, should also pay attention to avoid the influence of external_magnetic field on the multimeter.
4, the multimeter is used, should be placed in the conversion switch AC voltage maximum block. If it is not used for a long time, the battery inside the multimeter should be taken out, so as not to corrode other devices inside the meter after the battery leakage.
To je, v neprítomnosť z nameraný výkon pred the meranie, so to the multimeter ukazovateľ v poloha z nula napätie alebo nula prúd.
Mechanický nula vzťahuje sa na the the case of adjusting the head hairspring torque without power, due to movement, teplotné zmeny and iné ukazovatele may change; in general, this is not často potreba na adjust, focus on foot check and adjust, there is no change without adjust.
For the multimeter ohm block zero, it is actually the current through the head to reach the full bias current, and ohm block in an adjustable resistance, I=E / (R + r), R is the resistance value of the adjustable resistor, r is the power supply internal resistance, when the R reaches a certain value, I in order to reach the full bias prúd. Potom prijímať the meraný elektrický slnko Rx, potom I =E/(Rs+R+r), different current corresponds to different resistance to be measured.
① Place the stopper adjustment knob at ΩX1 stop.
Pripojiť the červená pero k the "+" terminal and the black pen k the "1" terminal.
③ will be shorted to the meranie koniec of the pen (lap spolu), pozorovať či the ihla je ukazovanie na the mierka čiara "Ω", as zobrazené in Obrázok 1-4 vyššie, such as not ukazovanie na nula should be adjusted "ohm nula" gombík, so to it body to nula.
④When adjusting the "ohm adjustment" knob, can not make the pointer in the 0", indicating that the table battery power is not enough, you should replace the battery inside the table.
The batérie v v multimeter by mali by by vymenené.
⑤ Many multimeter odpor z the highest multiplikátor blok, in add to press a high voltage battery (9V or 15V), should be replaced according to the requirements of the instructions. If you want to use this gear must be the corresponding battery.
