# Load Cell Troubleshooting
Load cells are super cool and can help reduce underload and overload situations. They are yet another sensor that can cause trouble.

## Load Cell Mismatch
The load cell mismatch fault rears its ugly head when any of **Weight Scaling** or **Weight Alarm** numbers differs between what's stored on the Stagehand and what's stored in Spikemark.
### How To Fix Load Cell Mismatch
* Click **Update Values** to send the **Spikemark Values** to the Stagehand\
**OR**
* Click **Accept Stagehand Values** to import the **Stagehand Values** into Spikemark.
### When does this typically happen?
* Starting a new show file
* [Swapping to a different Stagehand](#swapping-stagehand)
* [Reconnecting to a Stagehand (rounding error)](#reconnecting-to-the-same-stagehand)
#### In this image, the Weight Scaling numbers are different, so we are telling Spikemark to send the new "Spikemark Values" to the Stagehand
## Swapping Stagehand
If you've connected a new Stagehand, it's almost guaranteed that the stored Load Scale will be different from what is stored in the Spikemark file. In this case you want to push the Spikemark value to the Stagehand:
## Reconnecting to the Same Stagehand
If you haven't changed the show file, Stagehand controller or the hoist yet still encounter the Load Cell Mismatch, the issue is a rounding error. Computers are really good at storing numbers - they can store many digits to the right of the decimal. That's great for precision, but challenging to display and parse for human brains. Spikemark rounds the scale value to fewer digits than is initially stored on the Stagehand, and causes the mismatch fault to display. In this case, you want to **pull the Stagehand Value into Spikemark.**
