Load cells are used in several types of measuring instruments.
IMADA has published several models of load cells, such as ZTS-20N.
ZTS-20N has a 2000Hz sampling rate, so it is feasible to measure time-critical data such as response time.
However, the official software does not provide a protocol for time-synchronization.
This program can record the data from IMADA load cells without official software (except its drivers).
So, when we try to measure an Arduino-based actuator's response time, the program will send a request to Arduino and start recording force data simultaneously.
After the actuator actuates, we can get the response time from the force curve since the start-time is when we send a request to Arduino.
The response time we get will cover:
-
transmission time between Arduino and PC
-
actuating time of actuators
-
the latency of load cells measuring
-
transmission time between load cells and PC

-
Download the code, modify the packet to Arduino in this code.
-
Find the Arduino COM port from Windows Device Manager
-
Build the program and run it.
-
Enter the Arduino's COM port (e.g., COM4)
-
Enter the Arduino's Baud Rate (e.g., 115200)
The program will store the results into .tsv .
Open it by Excel/Numbers/other spreadsheet software.
The program will also calculate response time automatically. The results will be printed on screen.
