How to use the evaluation application software
Instruction Manual of ForceSensorEvaluationKit5
１．Communication setting with the board
Set the PC port number, board IP address, and port number, and then click “BIND” button.
Button “FREE” to cancel.
When communication with the board is established, Firmware and Hardware versions of the board are displayed.
２．Select the sensor to be measured
Select SPI, use check box of S1 to S5 to select the sensor1 to 5, and then click “SELECT” button.
Button “RELEASE” to cancel.
３．Enter "Interval" and click "INIT.“
４．Enter “Meas.Times”
*Start sensor operation.
While the sensor is operating, the “INT.” button turns to the light green button.
Click again to stop sensor operating.

How to use the evaluation application software
Instruction Manual of ForceSensorEvaluationKit5
５．Enter X Width and Y Width (Value can be changed even during measurement)
６．Set whether to update temperature
Temperature is updated at set time intervals by checking Interval. (Cannot be changed after START)
“Immed.” button updates the temperature at the timing of clicking the button.
(The key is only enabled after START.)
Temperature updating with the "Immed." button performs temperature updating regardless of the time
interval of Interval. *Compatible with ver.1.0.0.2
７．Click “START” button to begin measuring
８．Click “STOP” button to stop measuring
When the acquisition of the number of times set in "Limit" is completed, the measurement is automatically stopped.
９．Graphing can be disabled by removing “Graph” check box.
Processing capacity is broken in the graph drawing by the specification of the PC, and the data may not be acquired at the
cycle set by "Interval". Graph drawing disabled, data acquisition can be prioritized.
１０． Stop the sensor operation by clicking "INIT." *Stops sensor operation.
When the sensor operation is stopped, the “INT.” button becomes gray.

Evaluation application software “Function of offset calibration”
Instruction Manual of ForceSensorEvaluationKit5
The sensor output has an initial offset. Offsets also occur due to mounting and gravity.
It is possible to calibrate the offset deviation with the "CALIB." Button.
Press the "CALIB." Button again to cancel offset calibration.
↑Clicking "CALIB.“ button changes CALIB to red.
↑Point of calibration
Click "CALIB.“button again to
return CALIB to black.
↓
The average data of 10 times before pressing the
“CALIB” button is used for offset calibration.
↑Point at which offset
calibration was canceled

Evaluation application software “Data save”
Instruction Manual of ForceSensorEvaluationKit5
The data acquired by measurement can be saved with the "Save" button.
Data is saved in UserData folders with the file name “Log”＋“Date, Time”＋“.txt”(LogYYYYMMDDHHSS.txt).
The data will be saved in the following format.
Click “SAVE” button
