Hello,
I bought two field meter, which came without the PSU.
They run on DR35 batteries (NiMH, 10.8V 4000mAh).
The manual says:
EXTERNAL POWER SUPPLY
The instrument can be powered by an external DC source
The voltage provided must be from 10 to 18 volts.
Nevertheless, the charge of the battery is possible only if the voltage is greater than 15 Volts.
While the devices work will with a 12V 3A PSU, it won't charge their batteries.
I only have a 15V 4.6A PSU. I used it to charge the batteies and it worked just fine. However, I wonder if using 4.6A instead of the rated 3A will cause harm to the device and/or battery?
Will it charge "faster" and thus develop more heat or strain some components?
Thanks,
Vitor
