Watts Up Portable Plug In Power Meter
Watts Up provides lots of information yet it is simple to use. Only 6 values are displayed in the main modes. The other information is available in the detail mode. Clear English wording (not abbreviations) on the LCD is used to describe what is displayed.Watts Up incorporates sophisticated digital electronics that enable precise and accurate measurements. State-of-the-art digital microprocessor design utilizes high-frequency sampling of both voltage and current measurements for true power.
Power factor is captured so even phase-shifted loads such as motors are accurately measured. Fast, intuitive and easy-to-use, WattsUp? quickly and accurately measures any 120V AC appliance.
This Watts Up Standard Monitor will provide the following information: current watts, minimum watts, maximum watts, power factor, cumulative watt hours, average monthly kilowatt hours, tier 2 kilowatt hour threshold (used to calculate secondary kWh rates), elapsed time, cumulative cost, average monthly cost, line volts, minimum volts, maximum volts, current amps, minimum amps, and maximum amps, but does not have memory - you must write results down for your records. Note that this monitor's watt measure displays "true power", which factors in a device's power factor.
There are two other models to choose from :
- Watts Up Pro has memory and comes with Windows reporting software and communications cable to chart results and also logs a few more parameters than the standard. The PRO model also displays Power cycle.
- Watts Up Pro ES has extended memory to save more data over a longer period of time than the Watts Up Pro. It also has Windows reporting software and communications cable.
All models display this information:
- Cost - in dollars and cents
- Average monthly cost
- Average monthly kWh
- True power
- Cumulative power
- RMS voltage and current (amps)
- Maximum & minimum RMS voltage & current
- Maximum & minimum watts
- Power factor
- Duty cycle
All models are typically in stock and can typically ship the same or next day by method of your choice - UPS, FEDEX, parcel post, etc.
For more information, see the features, and specifications tabs above.
The Bottom Line:
The Standard model measures voltage and current thousands of times a second so it has an incredibly fast response time which enables you to "see the surge" of power when appliances are first turned on. The peak value display captures this surge so it is displayed even if it happens too fast to see live. The minimum RMS voltage display shows the line quality and voltage dips. Minimum RMS current and minimum watts can be used to monitor variances in appliances that run continuously.
Watts up? measures true power (including power factor). True power is what utilities charge for, which can be different than a simple voltage and current measurement (this is called "apparent power"). The duty cycle display shows the percent of time a load is above a preset threshold level. For instance, this threshold can be set to 100 watts and with a refrigerator the duty cycle display will show the percent of time that the compressor is running. A high reading may indicate a bad motor or low freon.

Troubleshooting hints & tips
can easily rate various appliances in terms of the ACTUAL power use. Can measure power levels, or the cumulative use.
The Bottom Line:
This device let you measure the actual power consumption by various devices and appliances, from single watts to 2 KW. It is handy for sizing power lines within the house, sizing uninterruptable power supplies for computers, comparing appliances on power use.
Measures almost everything you want to know about power consumption of any appliance. Very easy to use. Hardy.
Nothing I can think of.
The Bottom Line:
Great features for the price.
