Yes, I tried calibrating on syringes with similar size, but it is not as precise as calibration tool - alaris.
I saw offer on partsource and despite of price level, I not sure if it can pass EU customs. Alaris requires calibration on 10,15,20,25,30mm due to service manual. I will try to manufacture in on my own.
Alaris representative in here is not going to sell service tools, even if price will be much higher than on partsource.
Fresenius Agilia syringe pumps also requires service tool - force tool, displacement, syringe size.
