For a beginner, ano talaga yung difference? Cheap UNI-T or Aneng vs Fluke 117, yung pera mahal lang ba dahil sa brand, or may real differencia?

Sa career ko nakapag-handle ako ng tatlong meters, first was a Yoke meter from Raon noong 1989, second a Sanwa, current Fluke 117. Mga differences na tangible:

• Input protection, yung Fluke nag-saved sa akin once when I accidentally probed mains while in current mode. Cheap meter would have exploded.
• Accuracy on AC current, yung mura, off by 10-20% sometimes. Fluke parang 1%.
• Response time on transients, Fluke catches sudden dips, cheap meter just averages and you miss the issue.
• Build quality, pwede mong ihulog without worry.

Pero yung beginner-only use cases (DC voltage, continuity, basic resistance), wala namang pinagkaiba talaga yung output. Question is: kelan ka mag-uupgrade?

Daily-driver pa rin Fluke 117 sa shop. Hindi ko maipakita yung pera difference sa customer, pero yung peace of mind when probing a board na hindi mo alam yung max voltage, walang katumbas.

Yung Aneng AN-870 yung dressier-than-it-deserves cheap option. PHP 1200, 4-1/2 digit, true RMS. Comparable accuracy sa cheap Flukes for DC. Pero input protection isolation testing, hindi ako kumpiyansa. Hindi ko ito gagamitin pang-mains work.

Para sa hobby na low-voltage purely: even a UT139C is overkill. UT33C (~PHP 900) does the job for student budgets.
