The remote mounted manifold configurations currently acceptable within the NAM-standard NSS are the following Astava model codes:
M5   M6   M8   M16  M17
These new configured models must also be applied in case of revamping or replacement of old instrument manifolds. To guide you from the "old" model codes to the new model codes an overview is given below. For more technical background on remote mounted manifolds please, click here (Pdf, 105 Kb).
