The High Speed Inputs can be used with either dry or wet field contacts. For Wet
contacts, the common rides on a unit-generated Nominal 15V DC. No user program-
ming is necessary to use either wet or dry field contacts.

5.10: IRIG-B Connections
IRIG-B is a standard time code format that synchronizes event time-stamping to
within 1 millisecond. An IRIG-B signal-generating device connected to the GPS
satellite system synchronizes Nexus® 1250/1252 meters located at different
geographic locations. Nexus® meters use an un-modulated signal from a satellite-
controlled clock (such as Arbiter 1093B). For details on installation, refer to the User’s
Manual for the satellite-controlled clock in use. Below are installation steps and tips
that will help you.
Connection
Connect the (+) terminal of the Nexus® meter to the (+) terminal of the signal gen-
erating device; connect the (-) terminal of the Nexus® meter to the (-) terminal of
the signal generating device.
