The GT310 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 GT310s or one GT310 and one GT320 (essentially, a
GT310 with a dual dot-matrix display instead of a dual 7-segment
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, consider purchasing
General’s RD330 Remote Display with Memory as an optional
accessory. The standalone 4 in. x 4 in. unit, which uses the same
wireless transceiver module as the GT310 and GT320, 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 GT310 display are
compactness and portability.
Another key feature of the GT310 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.
