## Questions & Answers

**Q: I want to record power outages and hopefully sags/surges in an AC outlet, not necessarily under load. Can it do this?**
A: This logger is designed to monitor energy usage of a period of time.  It is not designed to capture transient events like sudden sags or surges.

**Q: What electrical values does it collect? just watts? of kwh, current volts?**
A: The UX120-018 data logger supports the following measurements: AC Current, AC Voltage, Amps (A), Kilowatt Hours (kWh), Power Factor (PF), Volt-Amps (VA), Volts (V), Watt Hours (Wh) and Watts (W).

**Q: What type of usb cable is needed to connect to the logger?  micro usb? mini usb? proprietary?**
A: The logger requires a type A to mini B standard USB cable.  They are very common and widely available.

**Q: Where is the pro software (as in specific url)?  The download site deosn't seem to work.**
A: The pro software is paid software, you'll need to purchase from Hoboware.  The standard software is what is free on their website.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Very nice wattmeter
*by E***A on June 15, 2023*

My expectations have so far been greatly exceeded. The free software works well. I have not as yet attempted to validate the readings except to eyeball compare it to two other power meters. So far it seem at least reasonable but my impression is that it is accurate.My initial use has been to perform thermal/power qualification on gaming PC's running Blender, Cinebench, OCCT power and other such workloads. The power consumption plots collected in those workloads seem to match the system activity very well so (at the minimum) I feel confident in using it at least as a relative measure. I have attached a sample plot of the power draw of a system running Cinebench R23 on a PC that hits 40K points in the multicore workload. The plot exhibits the expected behavior though it shows an interesting and unexpected (to me) change in the RMS voltage over time.There are two main reasons I wanted this device. (1) my UPS seems to be shutting down due to excessive load om overnight OCCT thermal testing. I want to record the power draw of the UPS to insure that the power is not shutting off. I also want to record the power draw of the system itself to better understand the circumstances.Notes:(0) The construction and quality is quite good though it is a bit expensive considering what is provided.(1) I will eventually try to run the software on Linux under Wine. I believe it should just work.(2) It comes with two AAA batteries preinstalled. The manual claims these should last for 6 months in the worst case. This is good because annoyingly, you have to significantly dismantle the power measurement unit to replace the batteries.(3) As far as I can see, there is no simple means of implementing a scripted start and stop of a measurement.(4) This meter will be good for monitoring PC power consumption whilst gaming. It should at least be useful determine whether there is a power aspect of game crashes.(5) the fastest sample rate is one per second. I'd like it to be faster.(6) I suppose the name HOBO is acronym for something. :)

### ⭐ Display Doesn't Work Properly!
*by C***E on November 2, 2023*

It was working normally for a while but now the display doesn’t work properly. I am unsure of how it broke.I've reached out to their customer service but haven't heard back.

### ⭐⭐⭐⭐ Power logger
*by M***B on January 7, 2021*

From limited use so far, appears to fall within design parameters. I don't give it 5 stars because in order to change the internal battery one must open the entire case. Also, the HOBOware app, which is very powerful, is somewhat confusing to use and limited in certain areas. Case in point, it is near impossible to remove or edit an obvious erroneous data point.
