Looking for a handheld device
Thread Content
Domestic instruments do not support the HRAT protocol, so using an HRAT handheld device is ineffective. What is needed is a handheld instrument that can be connected to the circuits of these domestic instruments, allowing for the setting of ranges, resetting, and zeroing of the instruments. I hope the experts can give me some advice.
It also depends on whether your instrument supports that protocol; if Hart doesn’t support it, then there’s probably no other communication protocol available either. Don’t even think about it.
As long as it can’t be operated with a handheld controller, it still has button controls, right? Isn’t that the same thing?
He just wants to avoid going to the site and adjust the meter right in the cabinet
It’s possible to go in and configure it without a protocol; I’m really good at this, huh
What protocol is used for domestic configuration, namely for current value signals?
To set the parameters, you need to access the inside of the meter; in any case, a communication protocol with the meter is required. Otherwise, you should buy a meter that allows for one-click reset via the panel buttons
