D1500 Data Sheet D-3
Example 1:
A load cell to be used in a weighing application is mated to a D1521 module.
The load cell is rated for 3mV/V, which results in a maximum ±30mV with 10V
excitation. However, in this application, the load cell is used only in tension
so its ideal output will be from 0 to +30mV.
The load cell is mounted in position with the weighing attachments. Clear
any offset data that may be stored in the D1521 module:
Command: $1WE (CZ is write-protected)
Response: *
Command: $1CZ (Clear Zero)
Response: *
Verify that the Zero Trim is cleared:
Command: $1RZ (Read Zero)
Response: *+00000.00
Obtain an initial offset reading from the load cell with no weight attached:
Command: $1RD (Read Data)
Response: *+00002.34
