• MODE INDICATOR – This area consists of arrow indicators on the bottom of the
screen, which point to an icon on the label which indicates whether the transmitter is in
conductive, clamp, or inductive mode.
• UNITS INDICATORS - During normal operation, or when the Rex transmitter is
measuring line voltage and impedance, it is necessary to display information to the
user with the appropriate units. The indicators on the LCD are as follows:
KΩ kilo ohm = 1000 ohms
A ampere, an electrical current measurement unit
mA milliampere = 1/1000 ampere
Hz hertz, a frequency measurement unit
kHz kilohertz = 1000 hertz
Connectors and Accessories
OUTPUT CONNECTOR - This 1/4” phone jack is used to connect the conductive
clips or the optional inductive clamp to the transmitter. The transmitter
automatically detects what accessory has been plugged in and adjusts its
operation and indicators accordingly. It is recommended that you turn the
transmitter's power OFF before removing or inserting accessories from/into this
connector or connecting to a utility. The connector is covered with a spring-
loaded plastic cap to prevent water and dust from damaging the transmitter.
DC INPUT CONNECTOR - This 5.5 mm/2.1 mm, center positive, DC power
connector is used to provide a DC voltage to charge the rechargeable battery.
The universal AC/DC power supply provided with the transmitter as a standard
accessory plugs into this connector to charge the battery. Alternatively, a DC
voltage source capable of supplying 22-30 VDC at 1.5A can be plugged into
this connector to charge the battery. The connector is covered with a spring-
loaded plastic cap to prevent water and dust from damaging the transmitter.
CAUTION
Do not connect conductive clips to live power lines. This is a Hazardous
practice and can permanently damage the transmitter. If you are connecting
to dead power lines, make provisions to avoid accidental activation of
power to the lines. Hazardous live voltage may be present at output
terminals in conductive mode.
