SWITCHING THE INSTRUMENT ON
:
(The METRALINE RLO-CHECK is switched off.) Press and hold
the «
ϕ
» until you hear a double acoustic signal.
The display is activated. The METRALINE RLO-CHECK is ready
for measurement. The last conducted balancing procedure is
active. The acoustic signal is not suppressed.
SWITCHING THE INSTRUMENT OFF
:
(The METRALINE RLO-CHECK is switched on.) Press and hold
the «
ϕ
» key for at least 2 seconds.
DEACTIVATING THE ACOUSTIC SIGNAL
:
(The acoustic signal is not suppressed.) Briefly press the «
ϕ
» key
.
The
icon appears. The acoustic signal is deactivated
(the acoustic signals for balancing and the voltage alarm remain
activated).
ACTIVATING THE ACOUSTIC SIGNAL
:
(The acoustic signal is deactivated.) Briefly press the
«
ϕ
» key.
BALANCING RESISTANCE OF THE
ACCESSORIES
:
(The METRALINE RLO-CHECK is switched on). Connect the
telescoping rod or the test probe to the measurement coil cable
and connect the cable to the «
Ω
» terminal.
Roll out the cable from the cable retractor and connect the end of
the cable to the alligator clip or the PE adapter for electrical outlets.
Activate the balancing procedure by briefly pressing the «
ϕ
»
key
twice. «
0 Ω
» is displayed.
Contact the end of the telescoping rod
or
the test probe with the
alligator clip or
the PE adapter for electrical outlets for
several seconds.
Blue background, 0.00, two short acoustic signals
followed by a continuous acoustic signal
indicate that balancing has been successfully
completed
(
the displayed value may fluctuate
due to measuring tolerance, for example
between 0.00 and 0.07).
The METRALINE RLO-CHECK is ready for measurement. The
results of this balancing procedure are retained until balancing is
conducted again, even if the battery is replaced or the
METRALINE RLO-CHECK is turned off
.
Red background, E01 and 0
Ω icon
:
Balancing has not been successful (e.g.
because resistance to be eliminated is too
high or the alligator clip didn’t correctly
contact the end of the telescoping rod
etc.). Results of the previous balancing
procedure remain active. Switch the
METRALINE RLO-CHECK off.

MEASURING PROTECTIVE CONDUCTOR
RESISTANCE IN THE INSTALLATION
:
(
The
METRALINE RLO-CHECK is switched on). Connect the
telescoping rod or the test probe to a measurement coil cable
and connect the cable to the «
Ω
»
terminal.
Roll out the cable from the cable retractor and connect the end
of the cable to the alligator clip or the PE adapter for electrical
outlets.
Connect the alligator clip or the PE adapter for electrical outlets
with the selected equipotential bonding reference point (control
panel, earth electrode, pin in an electrical outlet etc.).
Contact the protective conductors located nearby with the
telescoping rod or the test probe.
Important note!
If
resistance of the accessories has not been balanced (see E),
displayed resistance includes the accessories.

(The METRALINE RLO-CHECK is switched on). Connect the
telescoping rod or the test probe to the measurement coil cable
and connect the cable to the «

»
terminal
.
Connect a second test probe to a measurement cable and
connect the cable to the « AUX » terminal.
Briefly press the «

Contact both ends of the telescoping rod or the test probe
for
several seconds. (While doing so, you can
leave the alligator clip or the PE adapter for
electrical outlets connected to the equi-
potential bonding reference measuring
point).
Blue background, 0.00, two short acoustic signals

USING ONLY THE CABLE FROM THE
REEL COMBINED WITH AN ALTERNATIVE
MEASURING INSTRUMENT :
During routine daily work, a simple extension is frequently required
for connection to another measuring instrument. This is possible
with the help of the « AUX » terminal.
(The METRALINE RLO-CHECK is switched on). Undo all
connections (terminals and role-up cable).
Press and hold the «
ϕ
» key for at least 2 seconds in order to
switch the device off.
Connect the alternative measuring instrument to a measurement
cable and connect the cable to the « AUX » terminal.
The cable on the cable retractor is now available for use as an
extension cable.
The circuit set up in this way is protected by the internal fuse in the
METRALINE RLO-CHECK.
The METRALINE RLO-CHECK must remain switched off and may
never be switched on when an external measuring instrument is
connected
.
MEASURING PROTECTIVE CONDUCTOR
RESISTANCE OF A DEVICE NOT
CONNECTED TO THE CABLE REEL
:
(
The
METRALINE RLO-CHECK is switched on). Connect the
telescoping rod or the test probe to the measurement coil cable
and connect the cable to the «
Ω
»
terminal.
(The cable from the cable retractor which is connected to the
selected equipotential bonding reference point can remain
connected.)
Connect an additional test probe to a further measurement
cable and connect the cable to the « AUX » terminal.
Contact all accessible metal parts (of the device which is not
connected to the cable from the cable reel) and the protective
conductor of the device plug.
Important note!
If resistance of
the accessories has not been previously balanced (see G), the
displayed resistance includes the accessories
