1 First configure the boost duration using the
procedure above
2 Press and hold the
key until
BOOST
appears on
the transmitter LCD
3 The transmitter will automatically exit boost mode
after the selected duration

4.15 Transmitter Eco mode
When using alkaline D-Cells in Tx-5(B) and Tx-10(B)
transmitter models you can extend the effective use of
the batteries by enabling Eco mode.
In Eco mode the power output of the transmitter reduces
when the batteries can no longer provide the required
output power.
When Eco mode is active and the power output has been
reduced, the display alternates between
‘POWER‘ and
the current output power level.
The transmitter will emit three beeps every time the
power is reduced. It will then continue emitting two beeps
each minute whilst it operates at a reduced power level.
To enable or disable Eco mode
1 Press the
key to enter the menu
2 Scroll to the
BATT
menu using the
or
keys
and enter it by pressing the
key.
3 Scroll through the battery options using the
or
until
ALK
is displayed. Press the
key.
4 Use the
or
until
ECO
is displayed and press
the
key to enable Eco Mode.
Or
Select
NORM
and press the
key to disable Eco
mode.

4.16 Measure mode
The transmitter has the capability of providing
impedance measurements by determining the resultant
impedance across the crocodile clips of the Direct
Connection lead while connected to the utility. These
measurements can be useful when assessing sheath
fault severity. It is also possible to measure potential
voltage that may be present on utilities to warn of
potentially dangerous or harmful voltages present.
In measure mode the measurement is derived from an
AC signal applied to the utility from the transmitter
Impedance & voltage measurements
1. Connect the Direct Connection leads to the utility
and switch on the transmitter.
2. Hold down the
key until
MEAS
is displayed and
the measuring icon is activated.
The transmitter display will now indicate the voltage
level measured across the connection leads.
3. Press the
key once and the display will indicate
the impedance measured across the connection
leads.
The measurement icon will display the following
symbols:
Figure 4.13 Impedance and voltage measurements
4. To exit
MEAS
mode hold down the key until the
display reverts back to the normal operating screen.
Impedance measurements using
active frequency
1. Connect the Direct Connection lead to the utility and
switch on the transmitter.
2. Select the preferred frequency and output the signal.
3. Press the
key once and the display will indicate
the impedance measured across the connection
leads and also the output power of the transmitter.
4. Press the
key once to return to the normal
operating screen.
4.17 CALSafe
™
Usage logging equipped RD8100 locators can be set to
disable them once they are beyond the expected service
/ calibration date.
When the unit is within 30 days of the service due date
the unit will display at startup the number of days left.
The locator will stop functioning on the service due date.
CALSafe
™ is disabled by default. You can edit the
CALSafe service due date, and enable or disable the
function using the RD Manager PC software package.
Refer to the RD Manager operation manual for further
information.
