Why not use a battery back up system like one would use for a computer? We use to use one to run cooling fans on a Inferred Dryer if there was a power failure. When the power failed the battery back up ( USB) from a computer would run the fans to cool the lamp cases.

Hello there, when we utilize our U8903a with ethernet remote, at that point a similar estimation, we can do likewise from the front board gives us an altogether different outcome. Generally substantially more clamor and THD is estimated utilizing ethernet, than measure it from the front board. Is there any known issue with an answer for this, we could utilize? much appreciated, tamas

I installed a "whole house" generator panel (10 breaker 15,000 watts) and the garage, housing the sprinkler controller, is one of the switchable circuits. So, if I switch on the generator, such as during a brown out in the heat of summer, the sprinkler system works.

(Don't neglect the garage. Though possible, it makes it hard to get the car out if the opener has no power.)

Obviously, if I'm not home, there is no one to connect and turn on the generator, but we're always home.

Panel connection to main breaker panel:


60 foot 6 gauge x4 conductor cable to generator:


Generator stored in garage by back door:


Generator in position. Part of the engine and the exhaust sit outside:

So a U8903a is an audio analyzer, which indeed can measure THD (Total Harmonic Distortion)


But using the audio analyzer remotely with a battery backup or UPS would probably work.


If this is what you are asking, you do need to look at the power consumption, and determine the size of UPS required.
