FNIRSI HRM-10 Battery Internal Resistance Tester [ & Milli-Ohmmeter] Review

<< < (4/4)

mawyatt:
Anyone measured the actual test current level from the HRM-10?

How does this compare with the Yaorea 1030, 1035 and 2050?

Best,

Paul T:
Here's what I get when testing.  The resistance is reported on the HRM-10, the current on a ZOYI ZT-5566.

R (ohm)   I (mA)
0.0305   23.5 (multimeter in AC A)
2.168   2.45 (multimeter in AC mA)
50.69   0.034 (multimeter in mA, add 48.5 ohm resistor)

Double-Log chart attached.

These accessories would come as stand-alone spares and be purchasable for users who already purchased the HRM-10 with just jaws, not sure about the price, but the seller that sold me the HRM10 would reach out when he got them as spares.

Will likely also pop up at many other stores, but the mentioned source above got back with this listing.

In this review some voltage waveforms are shown:

It is not exactly an answer to your question, but it might provide some insight as to how the measurements are made.
