Load Cell 

Option

The Load Cell option (#170-00-4S-LC) consists of four low profile precision 

scales designed to take more accurate measurements of fluid dispensed from 

filtration tests. Information from each load cell is sent to the user’s computer 

via USB connections.

1.  Set up Load Cells in their designated positions on the base of the 4-unit 

filter press making sure that the corners of the base plates meet with their 

correlated posts.

Place load cells 1 and 2 to the left of their designated support rods and 

load cells 3 and 4 to the right of their designated support rods.

2.  Run the USB cables off to the side along the back panel.

3.  Plug the USB cables into the (#170-00-4S-013) 4-Port Hub.
