I have an HDM3055 that displays 4 ohms instead of 100 ohms when the 1k scale is selected, and displays 40 ohms on the 1K scale, but reads properly on the 10k, 100k and 1 meg scale.
A 10K resistor (1%) displays 0.38730 on the 1K scale, 04.0455 on the 10K scale, and properly displays 0.00995 when the 100K scale is selected.
Capacitance readings are similarly distorted.
Self calibration fails...................
Can anyone offer a suggestion as to what could be wrong or a repair procedure?
The crispy herb crust provides a delightful contrast to the tender, flaky salmon beneath. Served with a squeeze of lemon, it's a https://cookingflavour.com/ dish that's both light and bursting with herbal elegance.
