Thaum cov hlau ntes tau yuav, tag nrho cov ntaub ntawv yog khoob, yog li peb yuav tsum tau teeb tsa nws cov hlau thaum siv nws kom nws tuaj yeem ua tau zoo dua, yog li peb yuav tsum tau teeb tsa li cas?
Ua ntej tshaj plaws, qhov peb yuav tsum tau teeb tsa yog qhov rhiab heev. Peb yuav tsum tau teem lub rhiab heev ntawm cov hlau ntes raws li cov khoom kuaj pom, kom nws thiaj li tshem tau cov khoom uas muaj hlau impurities yam tsis muaj qhov yuam kev thaum ua haujlwm. Txhua yam peb yuav tsum tau ua yog ua qhov kev ntsuam xyuas rhiab heev ua ntej: yog tias koj xav tau tshem tawm cov khoom me me hauv cov hlau, koj tuaj yeem nias thiab tuav qhov hloov pauv tsis tshua muaj siab. Kev ntsuas ib ncig ntawm cov khoom yuav tsum ntsuas, thaum muaj cov khoom siv hlau, lub tswb nrov lossis kev co yuav raug tshaj tawm, thiab lub teeb ntsuab yuav tig mus rau lub teeb liab tib lub sijhawm; Thaum lub scan nres, lub suab lossis kev co yuav nres, thiab lub teeb liab yuav tig mus rau lub teeb ntsuab. Vim li no, qhov rhiab heev yog txo los ntawm ntau tshaj 5 zaug. Yog li ntawd, feem ntau nws yog ib qho khoom siv hlau loj uas ntsuas lub sijhawm no.
At this time, it is time to set the metal detector. We need to adjust the sensitivity when the detection interval does not meet the requirements of the rules, put the sound and oscillation switch in the "release" state, and use a small word Insert the screwdriver from the small hole on the handle of the detector and rotate it clockwise until it emits sound, then turn it counterclockwise until it stops sounding, and then turn it half a turn counterclockwise until the sensitivity meets the requirements.
Thaum teeb tsa qhov rhiab heev ntawm cov hlau ntes, qhov tseem ceeb uas peb yuav tsum paub yog qhov siab tshaj plaws ntawm cov hlau ntes no yog dab tsi. Qhov rhiab heev ntawm tus mob no tsis tuaj yeem txiav txim siab raws li qhov loj ntawm kev kuaj pom hlau.
