Module Connections
Versa Star Pro meters are compatible with pH electrodes with BNC connectors, ATC probes
and conductivity probes with 8 pin MiniDIN connectors and dissolved oxygen probes (both RDO
optical and polarographic) with 9 pin MiniDIN connectors – the same electrodes and probes
compatible with Orion Star meters, Orion Star Plus meters and Orion Star A series meters.
Make sure the module is properly inserted in the meter and the meter is connected to a power
source using the included universal power adapter.
