4. time is an initial period to be ignored 2 Pot VR2 is not currently used 3 Pot VR3 configures test time from 1 to 20 seconds Test time is the maximum time the tester waits for a flat zone It a flat zone is detected test is stopped immediately 5 Final Remarks Our Tester is VERY flexible and affordable It can be used as an standalone tester or integrated into a PLC PC PAC controlled panel It has traceability capabilities thru its serial remote control and monitor protocol Several testers can be parallelized for faster or lot testing The possibilities are many Let us know you testing and production needs We have the knowledge and experience to turn your requirements into a working solution
