MeterView XL Programming Software

The fastest and easiest way to program the meter is
using the free Meterview XL programming software.
This software greatly simplifies the programming
process and allows the user to save configuration files
for later use.

The meter connects to the PC via a provided micro-
USB cable and is powered by the USB connection, so
no additional power is needed during programming.

•

Care should be exercised to avoid ground loops
when connecting the USB to an active loop (e.g.
power supply, transmitter, loop-powered meter,
etc.). It is recommended to connect the (mA+)
terminal of the meter to the (-) terminal of a two-
wire transmitter and the (mA-) to the (+) of the
next device in the loop or to the (-) terminal of the
power supply.
