Hello all,
Do any of you have a HART Communicator model 275 with rechargeable NiCAD battery?
Our original charger has disappeared, and we need to procure one. We are running into conflicting information when researching what is needed.
It would be simplest if someone that has one takes a VDC multi-meter measurement, while charger is plugged in, with the meters positive lead touching the center of the jack plug and the negative lead touching the outside.
Is the 7.5V readout positive or negative? This will tell me what polarity charger to purchase.
