Locate the instrument close to the sample being analyzed, and to the Personal Computer (PC) if one is being used. A LEMO-6 connector for RS-232 serial output to a PC is on the right side of the instrument (see Fig 1-1above).

Make sure you install a fully charged set of batteries, or connect the instrument to an external power source (see “External Power Supply (optional)” on page 11), before switching the instrument on and exposing the sensor’s membrane to any liquid.
