Setting up a debugging room, matters related to the handheld controller 475
Thread Content
A debugging room is being set up; is it necessary to calibrate the handheld controller 475? Where to calibrate? Thank you!
There is no issue with calibration for 475, as it is merely a terminal for communication protocols such as HART and FF; however, 475 can be used to calibrate instruments
475 is a configuration tool that requires no calibration, similar to a mobile assistant on a computer
But the quality department requires that all testing instruments come with calibration certificates; otherwise it’s unreasonable and they won’t approve it. I’ve been looking for the relevant standards, but I can’t find them :'(
:) The testing instrument requires a calibration certificate! ! ! 475 is just a communication terminal. It can be monitored; the instrument data can be modified. Standard sources (testing instruments) are required when users calibrate the instruments, while intermediate tools do not need calibration certificates
Intermediate devices should also have inspection certificates (with an expiration date). If there are issues such as the inability to modify instrument data, it’s unclear whether the problem lies with the 475 device or with the instrument itself How to define it
No calibration is required. But you can’t just use a 475 – the pressure gauge, ammeter, regulated power supply, standard resistors: all of them need to be calibrated
If you decide whether there’s a problem based solely on the presence or absence of a certificate, then you’re not suitable for this job.
