How do I know if my load cell is damaged?
Signs that your load cell may be broken
- Inconsistent Display Readings.
- The Display Readings Keep Fluctuating Up and Down.
- The Display Will Not Return to Zero When the Load Has Been Removed.
- The Zero Balance Has Changed Dramatically.
- The Display Incorrectly Reads an Overload.
- The Display Reads No Load When a Load is Applied.
How do I reduce the sound on my HX711?
3 Answers. Adding a capacitor across the sense lines can help reduce noise and smooth the signal. Note that in the HX711 spec sheet (page 6) there is even a reference schematic/PCB that shows an RC network on the sense lines, it includes a 0.1uf directly across the sense pin inputs.
How does a load cell work?
By definition, load cell (or loadcell) is a type of transducer, specifically a force transducer. It converts an input mechanical force such as load, weight, tension, compression or pressure into another physical variable, in this case, into an electrical output signal that can be measured, converted and standardized.
How do you test a weigh cell?
A load cell test is performed using a digital multimeter. The digital multimeter is connected between the positive signal wire and the negative signal wire of the load cell. The output between them should be equal or to a value specified in the datasheet. This is the test for load cell output resistance.
How often should a load cell be calibrated?
Calibration interval should not exceed 12 months. The frequency of calibrations should be determined by the user of the load cell based on the following factors: Frequency of use. Severity of service conditions.
Is the hx711 load cell always 0kg?
The only thing I was able to find is that when I unplug one of the red wires from the HX711 is shows 6kg as weight… once I plug it back in it goes back to 0kg the load cells you are using are halve bridges.
Are there any readings from the hx711 configuration?
Even without any cell connected, you should see some datas coming out, probably close to 0.00 Being a newcomer, are you sure your sketch is correctly loaded in the Arduino ? have you tried other sketches ? What do you see on your terminal screen ? On your picture, there is a wire going to Vcc of the HX711 board.
How can I get my hx711 scale to read positive?
So try to switch A+ and A- on the HX711 and see if that helps. You need to do the calibration and (at least for me) the calibration always failed with the two red wires from A+ and A- beeing one way, so I had to switch them to be able to do the calibation and then switch them back to have the scale do positive readings and not negative.
