Battery testing is easier when the result is visible. ๐Ÿ”‹

Set your Sorting Mode limits, test 18650 cells or battery packs, and get a green pass or red check.

The HRM-10 also keeps history records, with 8 readings shown per page.

Save this workflow for your next electronics repair or battery build.

Ever read โ€œ01Bโ€ and assume it means 1ฮฉ?

Thatโ€™s the trap.

For EIA-96 SMD resistor codes:
01 โ†’ base value 100
B โ†’ ร—10
So 01B = 1kฮฉ.

30C follows the same logic:
30 โ†’ 200
C โ†’ ร—100
So 30C = 20kฮฉ.

Power off the board, isolate the resistor, and verify the result with the FNIRSI TMP-600.

Your charger says โ€œfastโ€โ€”but which protocol is actually active?

The FNIRSI FNB58 automatically checks supported charging protocols, then displays live voltage, current and power while your device charges.

Switch interfaces, test compatible protocol profiles, and inspect charging curves or power ripple from one screen.

Does 29.5 ยตF mean a 33 ยตF capacitor is still good?

We checked the same electrolytic capacitor with a component tester and a multimeter, then compared both readings with its marked tolerance.

Capacitance is only one clueโ€”loss, ESR, leakage, and circuit behavior may still reveal a problem.

One device. Three bench tools.

The FNIRSI TMP-610S combines a True RMS multimeter, oscilloscope, and DDS signal generator for electronics troubleshooting.

Three readings. One screen. Less switching around.

The FNIRSI DMC-100 Power Mode displays voltage, current, and calculated watts togetherโ€”useful when checking battery systems, vehicle circuits, and electrical loads.

One glitch. Thirty-two channels. Nowhere to hide.

The FNIRSI DLA-32 Plus captures up to 1 GSa/s on 1 or 8 channels, with up to 32-channel capture at 250 MHz in Buffer mode.
Add 4Gbit hardware memory, USB 3.0 transfer, and 170+ protocol decodersโ€”and complex digital signals become much easier to trace.

AUTO is a great starting pointโ€”but it canโ€™t fix every waveform.

Tiny signal? Adjust the vertical scale and timebase.
Jittery signal? Check the trigger level.
Nothing on screen? Verify the channel and probe ratio.

32 channels in something this small? Yeah, really.

Unboxing the FNIRSI DLA-32 Plus โ€” decodes 170+ protocols, comes with shielded reverse-proof cables so you can't plug it in wrong, mini IC test hooks for the tight spots, and a USB 3.0 cable for fast data transfer.

Built for anyone debugging digital signals who's tired of switching between tools mid-project.
