11.9 Identifying your refractometer
generation
The following instructions about inserting and removing Safe‑Drive are written for
Safe‑Drive generation 2.1. If you downloaded the instructions online or ordered a manual as
a spare part, it is possible that your Safe‑Drive system is of dierent generation and a
dierent set of instructions is needed. Vaisala strongly recommends upgrading the system
to generation 2.1, for more information see http://www.kpatents.com/support/product-
upgrades-and-notifications/documentation-upgrade-for-safe-drive.
The first place to look for the generation information is the retractor handle. If your retractor
is generation 2, the handle has the code G2. If your retractor is generation 2.1, the handle has
code G2.1. The
dierence between the generations is visible also when looking at the
retractor and the isolation valve. For more information, see the following figure.
