1. Training: one of our Technician had ever used the thickness measuring device which is similar function with your brand. Therefore, without your training, is it fine/easy for us to learn in using it by ourselves?
2. Calibration: I understand that when we purchase, you will give the calibration certificate that come with device, right? How about after the expiry date, how could we have its calibrated again: send device to AGR Thailand? Or send it to USA or request for AGR technician to go our factory?
3. Maintenance: from where we could ask for AGR service? Cost?
