Measuring Continuity
Figure 5. Continuity Zero Display/Switch and Terminal Settings
A continuity test is used to verify the integrity of connections by making a high resolution
resistance measurement. This is especially important for checking Protective Earth
connections.
Note: In countries where electrical circuits are laid out in a ring, it is recommended that you
make an end-to-end check of the ring at the electrical panel.
WWarning
• Measurements should only be performed on de-energized circuits.
• Measurements may be adversely affected by impedances or parallel circuits or transient
currents.
To measure continuity:
1. Turn the rotary switch to the RLO position.
2. Use the L and PE (red and green) terminals for this test.
3. Before making a continuity test, use the Zero adapter to zero the test leads. Press and
hold until the ZERO annunciator appears. The tester measures probe resistance,
stores the reading in memory, and subtracts it from readings. The resistance value is
saved even when power is turned off so you don’t need to repeat the operation every
time you use the instrument.
Note: Be sure the batteries are in good charge condition before you compensate the
test leads.

Loop Impedance (Line to Protective Earth L-PE)
Loop impedance is source impedance measured between Line (L) and Protective Earth (PE).
You can also ascertain the Prospective Earth Fault Current (PEFC) that is the current that
could potentially flow if the phase conductor is shorted to the protective earth conductor.
The tester calculates the PEFC by dividing the measured mains voltage by the loop
impedance. The loop impedance function applies a test current that flows to earth. If RCDs
are present in the circuit, they may trip. To avoid tripping, always use the Zl No Trip function
on the rotary switch. The no trip test applies a special test that prevents RCDs in the system
from tripping. If you are certain no RCDs are in the circuit, you can use the Zl Hi Current
function for a faster test.
Note: If the L and N terminals are reversed, the tester will auto-swap them internally and
continue testing. If the tester is configured for UK operation, testing will halt. This condition
is indicated by arrows above or below the terminal indicator symbol (
To measure loop impedance no trip mode:

To prevent tripping RCDs in the circuit:
• Always use the
• Preload conditions can cause the RCD to trip.
• An RCD with a nominal fault current of 10 mA will trip.
Note: To do a Loop impedance test in a circuit with a 10 mA RCD, we recommend a trip time
RCD test. Use a nominal test current of 10 mA and the factor x ½ for this test.
If the fault voltage is below 25 V or 50 V, dependent on the local requirement, the loop is
good. To calculate the loop impedance, divide the fault voltage by 10 mA (Loop impedance
= fault voltage x 100).

Earth Resistance Testing by Loop Method
You can also use the tester to measure the earth resistance component of the total loop
resistance. Check your local regulations to determine if this method is acceptable in your
area. You can use three leads or the mains cord to perform this test. Use the connection
shown in Figure 8 when making a 3-wire connection for earth resistance loop test. Zero the
test leads (see sequence for Loop Impedance measurement).

Line Impedance
Line impedance is source impedance measured between Line conductors or Line and
Neutral. This function allows the following tests:
• Line to Neutral loop impedance.
• Line to Line impedance in 3-phase systems.
• L-PE loop measurement. This is a way of making a high current, 2-wire loop
measurement. It cannot be used on circuits protected by RCDs because it will cause
them to trip.
• Prospective Short Circuit Current (PSC). PSC is the current that can potentially flow if
the phase conductor is shorted to the neutral conductor or another phase conductor.
The tester calculates the PSC current by dividing the measured mains voltage by the
line impedance.

Measuring RCD Tripping Time
Figure 11. RCD Tripping Time Display/Switch and Terminal Settings
In this test, a calibrated fault current is induced into the circuit, causing the RCD to trip. The
meter measures and displays the time required for the RCD to trip. You can perform this test
with test leads or using the mains cord. The test is performed with a live circuit.
You can also use the tester to perform the RCD tripping time test in Auto mode, which
makes it easier for one person to perform the test. If the RCD has a special nominal current
setting other than the standard options, 10, 30, 100, 300, 500 1000 mA, you can use a
custom setting with the VAR mode.
Note: When measuring trip time for any type of RCD, the tester first does a pretest to
determine if the actual test will cause a fault voltage exceeding the limit (25 or 50 V).
To avoid having an inaccurate trip time for S type (time delay) RCDs, a 30 second delay is
activated between the pretest and the actual test. This RCD type needs a delay because it
contains RC circuits that are required to settle before applying the full test.

WWarning
• Test the connection between the N-conductor and earth before starting the test. A
voltage between the N-conductor and earth may influence the test.
• Leakage currents in the circuit following the residual current protection device may
influence measurements.
• The displayed fault voltage relates to the rated residual current of the RCD.
• Potential fields of other earthing installations may influence the measurement.
• Equipment (motors, capacitors) connected downstream of the RCD may cause
considerable extension of the tripping time.
Note: If the L and N terminals are reversed, the tester will auto-swap them internally and
continue testing. If the tester is configured for UK operation, testing will halt and you will
need to determine why the L and N are swapped. This condition is indicated by arrows

The tester supplies ½x the rated RCD current for 310 or 510 ms (2 seconds in the UK). If
the RCD trips, the test terminates. If the RCD does not trip, the tester reverses phase and
repeats the test. The test terminates if the RCD Trips.
If the RCD does not trip, the tester restores the initial phase setting and supplies 1x

Measuring RCD Tripping Current
Figure 12. RCD Tripping Current/Switch and Terminal Settings
This test measures the RCD tripping current by applying a test current and then gradually
increasing the current until the RCD trips. You can use the test leads or mains cord for this
test. A 3-wire connection is required.

WWarning
• Test the connection between the N-conductor and earth before starting the test. A
voltage between the N-conductor and earth may influence the test.
• Leakage currents in the circuit following the residual current protection device may
influence measurements.
• The displayed fault voltage relates to the rated residual current of the RCD.
• Potential fields of other earthing installations may influence the measurement.
Note: If the L and N terminals are reversed, the tester will auto-swap them internally and
continue testing. If the tester is configured for UK operation, testing will halt and you will
need to determine why the L and N are swapped. This condition is indicated by arrows
above or below the terminal indicator symbol (

RCD testing in IT systems
RCD testing at locations with IT systems requires a special test procedure because the
Protective Earth connection is grounded locally and is not tied directly to the power system.
The test is conducted at the electrical panel using probes. Use the connection shown in
Figure 13 when performing RCD testing on IT electrical systems.

MAINTAINING THE TESTER
Cleaning
Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or
solvents.
Dirt or moisture in the terminals can affect readings.
To clean the terminals:
1. Turn the meter off and remove all test leads.
2. Shake out any dirt that may be in the terminals.
3. Soak a new swab with alcohol. Work the swab around each terminal.
Testing and Replacing the Batteries
Battery voltage is continuously monitored by the tester. If the voltage falls below 6.0 V
(1.0 V/cell), the low battery icon Mappears on the display, indicating that there is minimal
battery life left. The low battery icon continues to appear on the display until you replace
the batteries.
WWarning
To avoid false readings, which could lead to possible electric shock or personal injury,
replace the batteries as soon as the battery icon ( M ) appears.
Be sure that the battery polarity is correct. A reversed battery can cause leakage.
Replace the batteries with six AA batteries. Alkaline batteries are supplied with the tester
but you can also use 1.2 V NiCd or NiMH batteries. You can also check the battery charge so
that you can replace them before they discharge.
WWarning
To avoid electrical shock or personal injury, remove the test leads and any input signals
before replacing the battery. To prevent damage or injury, install ONLY specified
replacement fuses with the amperage, voltage, and speed ratings shown in the General
Specifications section of this manual.
To test the batteries:
1. Turn the rotary switch to the V position.
2. Press F3 > 2 seconds to initiate the battery test. The Voltage function display clears and
is replaced by the measured battery voltage in the secondary display for 2 seconds, the
Voltage function display then returns.

Testing the Fuse
A fuse test is performed each time you turn on the tester. If leads are plugged into the L and
PE terminals, the fuse test is skipped. If a blown fuse is detected, testing is disabled, FUSE
appears on the primary display, and the tester issues a warning beep.
You can also perform a manual check of the fuse.
To manually check the fuse:
1. Turn the rotary switch to
2. Short the leads and press and hold
