Watts Up Pro (No Longer Sold) (WU-PRO, discontinued)
Specifications and User Guide


Problem: Display (in watts) on the Watts Up Pro does not match the display in the Logger Pro or LabQuest App.
Solution: Press the Mode button on the device to toggle the units until watts are displayed.

Problem: Displayed data are incorrect.
Solution: Devices that turn on and off at high loads can cause the calibration data in the meter to become corrupt. If this happens, unplug and plug back in the meter.
This resets the calibration.
