Combined Loop and RCD Tester

USER MANUAL

GSAFETY WARNINGS

■Safety Warnings and Precautions must be read and understood before the instrument is used. They must be observed during use.

■Continuity of protective conductors and earthed equipotential bonding of new or modified installations must be verified before carrying out RCD tests,

or earth fault loop impedance tests.

■Do not leave the instrument connected to the mains supply when not in use.

■Circuit connections and exposed metalwork of an installation or equipment under test must not be touched.

■Ensure that hands remain behind guards of probes/clips when testing.

■The instrument should not be used if any part of it is damaged.

■Test leads, probes and crocodile clips must be in good order, clean and with no broken or cracked insulation.

■The battery cover must be in place whilst conducting tests.

■Voltage indicator LED’s cannot reveal a N-PE supply reversal.

■National Safety Authorities may recommend the use of fused test leads when measuring voltage on high-energy systems.

■When making a 2 wire measurement with the 3 wire lead set, for safety reasons the black test lead should be connected together with the green test.

Users of this equipment and/or their employers are reminded that Health and Safety Legislation requires them to carry out valid risk assessments of all

electrical work so as to identify potential sources of electrical danger and risk of electrical injury such as inadvertent short circuits.

Some national safety authorities recommend fused leads for voltage measurement on high energy systems. If RCD or Loop tests are made it may cause the

fuse to rupture, and so they must be used with caution on voltage testing.

NOTE

THE INSTRUMENT MUST ONLY BE USED BY SUITABLY TRAINED AND COMPETENT PERSONS.

PREPARATIONS FOR USE (ALL INSTRUMENTS) GENERAL OPERATING INSTRUCTIONS

Tests lock (LRCD 220 only)

The LOCK Lindicates when the [Hi] current loop test range is locked

ON.

It is activated by holding down the Llock button, and pressing the

[TEST] button. When activated, the [Hi] current loop resistance

measurement will start when the instrument is connected to a voltage.

The test lock remains on for 30 seconds, after which it resets to off.

Test inhibit

The following conditions may cause the instrument to inhibit testing:

Out of range supply voltage

If an out of range voltage or frequency exists on the circuit under test,

or on a very noisy mains supply, testing will be automatically inhibited.

The RCD tests requires a minimum supply voltage to operate.

If the warning <***V is displayed, the supply voltage is below that

required to perform an RCD test.

*** = supply voltage indication.

Overheating

Repetitive loop testing generates heat within the instrument. If this

heat becomes excessive the instrument will warn the operator and

prevent further testing until the instrument has had a chance to cool

down.

Fuse Blown

A fuse blown will prevent the instrument from making further tests.

The fuse indicator will be displayed.

Batteries

The Megger LRCD series instruments are supplied with batteries fitted.

When batteries become exhausted, refer to page 19, battery replacement.

WWaarrnniinngg::Do not switch the instrument on with the battery cover

removed.

Preliminary test lead check

Functional verification

Before each use of the instrument visually inspect the test leads, prods

and crocodile clips to confirm that their condition is good, with no

damaged or broken insulation.

Default voltmeter

The default voltmeter automatically operates in all test modes, indicating

connection to a live system.

Auto Power-down

To extend battery life the instrument will automatically switch off six

minutes after the last operation.

The instrument can be switched off manually by selecting [OFF] with the

rotary switch, or switched back on again by pressing the [TEST] button.

Backlight operation (LRCD 220 only)

The LRCD LCD display may be backlit, to allow readings to be seen in

adverse lighting conditions. The backlight function can be selected at any

time while the instrument is switched on by pressing the BACKLIGHT J

button.

The backlight function will switch off automatically 15 seconds after the

instrument has finished testing.

Display warning symbols

GRefer to user manual.

Any time the warning triangle is displayed the operator should refer to the

user manual for further information.

LRange lock

Displayed at any time the [TEST] button is locked in the on position.

Setup Procedure

Reverse polarity or line/neutral swapping

This feature is only available on the following models:

LRCD200-EN-SC LRCD210-EN-SC LRCD220-EN-SC

LRCD200-FR-SC LRCD210-FR-SC LRCD220-FR-SC

LRCD200-DE-SC LRCD210-DE-SC LRCD220-DE-SC

LRCD200-NL-SC LRCD210-NL-SC LRCD220-NL-SC

LRCD200-ES-SC LRCD210-ES-SC LRCD220-ES-SC

The set-up menu allows the user to change the way the instrument

behaves when testing on a supply with Line and Neutral connections

swapped. Tests may be permitted or prohibited.

To select Polarity reversal acceptance or rejection:

1. With the instrument switched OFF, hold down the [TEST] button and

turn the range knob to any ON position.

2. Keep the button held down until the instrument displays the ‘SET’

warning.

3. Now release the [TEST] button.

4. Press the [TEST] button again to view the current setting for line/neutral

swapping.

5. The display shows ‘L+L’ (instrument will perform tests with L & N

your type of socket outlets, do not use an adaptor. You may change the

plug once only by cutting the cord as close to the plug as possible and

fitting a suitable plug.

The colour code of the cord is:

Earth (Ground) Yellow/Green

Neutral Blue

Phase (Line) Brown

Note: A plug severed from the power cord must be destroyed, as a plug

with bare conductors is hazardous in a live socket outlet.

Test lead connection

The supplied test leads should be connected to the appropriate sockets on

the rear of the instrument marked L0 and L1, or to the 3 way test socket.

Standard test probes and crocodile clips are supplied for connection to the

circuit under test.

The test lead supplied with the LRCD200, LRCD210 and LRCD220 provides

connection for 3 wire testing, using the 3 wire (red, black and green) lead

set (6220-782) or mains plug lead (6220-740).

Application

This instrument may be connected live to earth or between live

conductors of systems that have a rated voltage of 300V a.c. rms to earth

and an installation (overvoltage) Category III or lower.

This means that the instrument may be connected to any fixed wiring of a

building installation, but not to primary supply circuits such as overhead

cables. To maintain user safety and ensure accurate measurements, only

use the test leads supplied or by Megger Limited.

swapped).

6. Press the [LOCK] button or the PFC button to change the setting.

7. Press the [TEST] button to exit from the set-up menu.

RCD Touch voltage selection

TToosseetttthheettoouucchhvvoollttaaggeeiinnhhiibbiittlliimmiitt::

1. With the instrument switched OFF, hold down the [TEST] button and

turn the range knob to any ON position.

2. Keep the button held down until the instrument displays the ‘SET’

warning.

3. Now release the [TEST] button.

4. Press the [TEST] button twice to view the current settings for the touch

voltage.

The display shows the fault voltage limit, ‘25 V’ or ‘50 V’.

If the fault-voltage display is active, a bar-graph display will also appear.

5. Press the [0º/180º] button to change the limit setting from 25V to 50V

and back.

6. Press the [TYPE] button to turn bar-graph display ON or OFF.

7. Press the [TEST] button to exit from the set-up menu.

Test leads

All test leads form part of the measuring circuit of the instrument and

must not be modified or changed in any way, or be used with any other

electrical instrument or appliance.

The mains plug test lead supplied with the Megger Tester is a test lead that

forms part of the measuring circuit of the instrument. The overall length

of this lead must not be altered. If the power cord plug is not suitable for
