Hi bear. I have never heard of that charger. I googled it and found it lacking: any charger that touts how strong it is and how many miles of fence it can charge but does not say how many joules it is is not worth buying. Recommended brands that I have used are speedrite and Gallagher. Premier is also good but I have not used them. Consider: 15 miles of single strand twine for cows, ie out of the weeds, is very different from pouldtry netting which sags into the weeds. You'd never get 15 miles of that. The 1 joule plug in speedrite I have cost about $100 and is fine for bees and bear. I've had it about 5 years with no problems (it is plugged in in a shed). So I'd recommend and upgrade. Around here big box stores sell junk like zareba, which is Maybe fine for horses but certainly would never keep our sheep in, even their "30 mile" ones....
However, how many volts does the fence test at when it is working and how many volts does the ground rod test at the same settings? What is the minimum and maximum reading on you meter? Do you have galvanised or copper ground rods? And what crofter said is good too.
Bottom line, get a better charger. A bear can "sniff" the voltage before he touches the fence. I have heard of bear cought on trail cam that would come to the fence, sense it's voltage, and sit down and wait (because they had somehow discovered it worked intermittently). When the charger malfunctioned he would get up and calmly walk through the fence to tip the hives....
Good chargers and fences are good for beekeepers.... Good luck!
