Connect GPS cable to GPS INPUT serial port on back of instrument. The Veris instrument is
designed to accept GPS input in NMEA format via an RS232 connector. Note: GPS signals are
frequently affected by electrical interference from magneto electrical systems. If your vehicle uses a
magneto, consider powering the Veris instrument with a 12-volt battery or converting to an alternator
system.

The Veris 3100 is shipped with an accessory power plug. If an alternative connection is desired,
make sure that the unit is properly connected to a power connection that is not controlled by the
ignition switch. If connecting directly to the battery, we suggest a 3 amp. in-line fuse is installed
between the battery and the instrument. Important – Do not allow moisture to enter the
instrument, and do not pass strong magnets near the unit.

Signal Testing – The Veris 3100 is shipped with an Instrument Test Load (Part No. 10447) that will
enable you to quickly check the instrument to ensure that it is functioning properly. To perform this
test, do the following:

1) Disconnect the signal cable from the 9-pin (signal) terminal on the instrument.
2) Connect the test load to the signal terminal.
3) Switch on the unit and go into “data acquisition” mode.
4) The display should show: (approx.)

Shallow

Deep

5) If the readings vary greatly (more than one whole number) contact our service

department.

6) Once the test is complete, remove the test load and reinstall the implement signal cable.
