Sw13 scale reads HHH - NATASHA COLLIS Gold nugget ring with mixed diamonds

You don't. one of the feet is broken and can't register pressure anymore. You can try to disassemble the entire machine, find the exact pressure sensors and replace them, but these will probably be way more expensive than the original scale.

There is a similar problem on this site and solution.
My digiweigh scale reads HHH What does this mean and how do fix it

I thinkn there is a reset button to press with no weight on the scale if I remember correctly. Might have to calibrate with the test weight too if the calibration is messed up (not likely though).

That means that it is out of range. It is trying to weigh something that is too light. IT could be the sensor is bad or loose.

Try this - While it is off, press and hold both the mode and the tare* keys at the same time and press the On/Off key - Release the keys and observe the display - cycle through a series of numbers. Press the mode key once and observe the display "CAL 0" "100.00" then similar numbers as before. This step calibrates

corn syrup

It worked on mine,
I pushed Mode, Power, Tare at the same time.
It came up in Cal mode.
I added penny's till it was 995 or so then added small pieces paper to it till it was 100 then up popped passed. I turned it off then it works fine now.
Thank You!!!!!!!

My fuzion fz100 scale reads hhh how can I fix it

If the receiver and/or the transmitter display LLL or HHH instead of the probe temperature,
wait for probe to reach room temperature. If LLL or HHH is still displayed it is likely the
internal probe wire has shorted out either through moisture or heat damage.
