Illuminometer - Muaj nuj nqi:
1. Taug qab thiab sau cov kev hloov pauv ntawm lub teeb pom kev thoob plaws tag nrho cov txheej txheem, nrog rau lub sijhawm kaw ntev (cov ntaub ntawv kaw txhua txhua 15 feeb, uas tuaj yeem kaw tau ntev txog 5 lub hlis lossis ntev dua), sib xyaw cov ntaub ntawv khaws cia, kaw, thiab xa tawm.
2. Lub tshuab tag nrho muaj kev siv hluav taws xob tsawg thiab siv los ntawm lub roj teeb lithium (built-in), nrog lub roj teeb lub neej ntev tshaj li ib xyoos.
3. Muaj ob hom software, Suav thiab Askiv, thiab koj tuaj yeem xaiv los ntawm lawv. Cov lus Askiv version muaj thoob ntiaj teb universality.
4. Lub software muaj zog ua haujlwm thiab yooj yim saib cov ntaub ntawv.
5. Tsis siv neeg tsim cov ntaub ntawv kaw lus, thiab cov ntaub ntawv khaws cia tuaj yeem ua tiav siv EXCEL, WORD, lossis software tshwj xeeb.
6. Lub sijhawm kaw lub sijhawm tuaj yeem teeb tsa arbitrarily ntawm 2 vib nas this mus rau 24 teev.
7. Cov ntim me me (58 × xya caum-ob × 29mm), kev ua haujlwm yooj yim, kev ua haujlwm tau zoo (tsim rau qhov chaw hnyav, tsis muaj cov ntaub ntawv poob thaum lub zog poob).
8. Nws tuaj yeem ua lub tswb nrov.
