Review: FNIRSI HRM-10 Internal Resistance Tester

[@JAKOB1977]

Thats not to shabby.. do like that you compare it to another bench millioohm meter. You can see the fw revision on nr10 in the menu.. "factory default" many tends to not wanna click on that, as hey think it will reset, but you do have a step more, and in there you will get fw info... you will likely have FW0.4 like my own unit..while the latest in the official protocol cloud is still listed as FW0.3. Its pretty straight forward to just cherryrig some cheap kelvin with an GX12-4pin connector, as clamp is far from ideal for bench uecases..

So if i need to know the GEL agm battery need to be changed or not Can i just use multimeter with feature to measure batteries ?

[@NearFarMedia]

If you know the expected internal resistance limits for your battery, then this instrument can be used to see if the battery is healthy or needs to be replaced. If the internal resistance measures more than the specifications, the battery needs to be replaced.

I will be comparing it to a 16 bit 32s pair of Revo DPL8s PL chargers on .xls logging 10 hz. It shows five digits after the zero on teh ACIR logs. Decimal accuracy of the DPL8s calibration is to +/- 1mA Measurement accuracy: Voltage resolution: 78uV (16 bit) Voltage tolerance: +/- 6mV
