HPS141 not calibrated


I purchased the HPS141 component tester add-on for the handheld oscilloscope and have been pleased with its performance until I tested a capacitor. When I test any capacitor it displays the capacitor’s attributes for about a second, and then it blanks the screen and says “not calibrated.” How do I calibrate the device? It seems to do the same with transistors, although not with resistors.

Any assistance would be appreciated!


That’s weird it should come calibrated from the factory.
To enter the calibration procedure you connect all 3 leads together and you push the button and follow the on screen instructions. Also make sure to have a capacitor with value between 100nF and 20µF by hand when doing the procedure.


Awesome - got it! Thank you!
