Steps of Correction

The correction is made to match DVP02LC-SL with the weight of the load cell, including the correction
by MPU and correction by software. The correction by MPU is done by first connecting DVP02LC-SL to
a DVP series PLC MPU and correcting by using TO/FROM instructions. The correction by software, on
the other hand, is done by connecting DVP02LC-SL to a PC via a RS-232 communication cable and
correcting on the software.

7.1 Correction by MPU

In this example, we connect DVP02LC-SL to a DVP series PLC MPU and correct CH1 by TO
instruction.
1. See 4.1 for how to connect DVP02LC-SL to the left side of the PLC MPU and supply power to
the two devices.
2. Connect the load cell to CH1. See 4.4 for external wiring.
3. Set up every parameter and eigenvalue according to the actual measuring requirements and
specifications of the load cell. In this example, we use the default settings of all parameters.
