Q1: What is the HP-KJS1 used for?
A: It’s used to measure residual stress using the indentation method, acquiring strain signals and converting them into stress results through data processing.
Q2: How many measurement points can I run at once?
A: The system supports 10–100 channels optional, so you can scale from small tests to multi-point measurement.
Q3: Is the operation complicated?
A: No. It uses an LCD touch screen with a simple menu and supports automatic testing.
Q4: How do I export or store the data?
A: Use the USB port for communication and storage, and process/report data on a PC.
Q5: What types of materials are best suited?
A: It’s mainly intended for cases where material hardness is below HRC50.
Q6: What accuracy can I expect?
A: Key specs include ≤ ±0.1% measurement error and ≤ 10 MPa stress error (actual performance depends on test setup and material condition).
Q7: Does it support automated zeroing?
A: Yes—there is 3-point strain auto-zeroing built in.
