The GT320 can be part of three different kinds of wireless
communication schemes.
1. The meter includes a small USB receiver—called a dongle—that
enables any PC to display all the information shown on the unit’s
display. The “Going Wireless” section of this user’s manual provides
instructions for downloading the software needed to activate this
connection. The advantage of using a PC’s monitor to display the
meter’s measurements is readability: readings sent to the screen
of a laptop or desktop computer are several inches high—large
enough to be visible across a room.
2. With two GT320s or one GT320 and one GT310 (essentially, a
GT320 with a dual 7-segment display instead of a dot matrix
display), each meter can be configured to display its own
measurements on its upper readout, and receive and display the
other meter’s measurements on its lower readout. Both models
include the wireless transceiver module needed to “share” readings
remotely—improving safety in the process—in this way.
3. For even greater remote display versatility, use the GT320 with the
included RD330 Remote Display with Memory. The standalone
4 in. x 4 in. unit, which uses the same wireless transceiver module
as the GT320 and GT310, can not only display the readings of two
multimeters simultaneously on its own dual LCD with 0.67 in.
(17mm) high digits; it can also memorize up to 99 readings or pairs
of readings. In addition to its memory, the advantages of using the
RD330 as a remote GT320 display are compactness and portability.
Another key feature of the GT320 is its pair of double-insulated fused
test leads. Like NCVD/NCCD and wireless device-to-device
communication, the fuse in the red test lead offers the electrician
safety and convenience. It not only prevents excessive currents from
flowing through the meter, potentially injuring the user and damaging
the meter. In addition, the position of the fuse makes changing it fast
and easy. In many other multimeters, changing a blown fuse requires
the user to open up the instrument.
The red lead has a unique square plug. The meter's use of a square
(+) jack prevents potentially damaging use of industry-standard round,
non-fused leads.
