1. Activate the DVM by depressing the POWER ON button. Allow 6 seconds for
unit to self test and calibrate. The unit is ready for testing when the 0.0V
reading is displayed.
2. LOW BATT indicates a battery voltage of less than 2.048VDC. If this is
displayed, the ModieLamp must be recharged using the charger provided, or
via a computer or vehicle USB port.
3. Place the ModieLamp test probes on to the test points.
4. The voltage between the test points will be displayed on the LCD.
5. To enable the test voltage to be temporarily held and displayed following
removal of the test probes from the test point, press HOLD. Pressing HOLD
again returns the unit to its normal metering mode.
6. To enable the peak value of voltage to be captured, press PEAK HOLD. The
maximum value will be constantly displayed and only updated if a higher
value occurs. To deactivate this feature, press PEAK HOLD again.
7. DVM auto switch off occurs after 5 minutes (factory set to user
requirements)
8. Backlight:
• Evaluation model: Backlight automatically switches on when unit
powers up.
• Production model: Backlight will be automatically activated when
ambient light falls below a factory set level via a light sensitive sensor
adjacent to the display. Backlighting can be activated if required
during high ambient lighting levels by covering the light sensitive
sensor opening with a nger or thumb.

GENERAL OPERATING INSTRUCTIONS
Important Note:
Ensure only appropriately trained and qualied personnel use the ModieLamp.
Standard Test-Lamp Usage:
The ModieLamp can be used as a standard set of test-lamps with 480VAC,
415VAC, 240VAC and Load-Glow being readily identiable from the brightness of
the incandescent lamps.
• 480VAC: Full Glow ++ (Rare but occasionally still found in Australia)
• 415VAC: Full Glow (Phase - Phase)
• 240VAC: Half Glow (Phase - Neutral/Earth)
• Load Glow: Ruby Red (Usually apparent when testing across a service
fuse holder with the fuse removed). The supply feeds any connected
load (including the electricity meter voltage coil) via the test lamps.
The level of glow depends on the impedance of the load. The lower the
impedance, the brighter the glow.
General Instructions:
1. Always check the ModieLamp before use.
a. Check leads for any damage to the cables, probes and inline fuse-holder.
b. Check for rm connections between probes, inline fuse-holders and end-
plugs
c. Check for clean and corrosion free test probes.
d. Make sure there are no dangerous cracks or chips.
2. Check the ModieLamp using the Modieprove proving unit.
ModieProve
a. If the ModieProve needs to be tested, there is provided a dummy test
load that can be plugged into the test-points to indicate that the
ModieProve is serviceable.
b. Connect the ModieLamp probes to the ModieProve terminal sockets.
c. If the ModieLamp is serviceable, an LED and a sounder will activate. If
the ModieProve does not activate then the ModieLamp is faulty. It should
be tagged unserviceable and the appropriate authority informed for
repair and replacement.
GL McGavin ModieLamp Manual Page : 7
POLARITY TESTING (GENERAL)
3. The test item connection points should be clean and free from corrosion to
ensure a good contact between the test probe and the test connection point.
4. Use the ModieLamp probes to make contact at the test points.
5. Should the ModieLamp fail to indicate the presence of voltage, it is essential
to test the ModieLamp with the Modieprove proving unit immediately. If the
Modielamp proves serviceable, proceed to next step, otherwise it should be
tagged unserviceable and the appropriate authority informed for repair and
replacement.
6. If upon re-connection to the testing point the unit still does not indicate,
then the test points tested can be considered de-energised.
3ø and 1ø polarity testing can be readily carried out using the ModieLamp.
Most utility companies have their own preferred method of performing the test
depending on location of test and the testing conditions.
In lieu of a preferred company work method, the following procedure can be
adopted to carry out a basic polarity test at a consumer mains switchboard.
Polarity Test of Mains at a Consumer
Switchboard:
1. Turn OFF the main switch/s and any circuit breakers or remove all fuse
carriers.
2. Conrm that bonding conductor to a service support is not connected and
that main neutral is still disconnected from MEN link.
3. Connect supply.
4. Test between the main neutral conductor and the line terminal/s of the main
switch/s. On a multiphase installation, between phases.
a. On a single phase installation the test lamps should light up showing
half-glow, proving that the test lamps are in order and that the required
supply is available.
b. On a three phase installation the test lamps should light up showing full
glow between any two phases and half glow between any phase and
neutral.
5. Test between the main neutral conductor and an independent earth
electrode. The test lamps should not light.
6. Test between an independent earth electrode and the line terminal/s of
main switch/s. The test lamps should light.
GL McGavin ModieLamp Manual Page : 8
NOTE: Failure of the test lamps to light during this test indicates
that the resistance between the independent electrode and the
general mass of earth is too high. If this is the case (and a better
earth cannot be established), disconnect the ModieLamp from the
testing points, unscrew and remove one of the lamps from the lamp
socket, and re-attach the ModieLamp to the test points. The digital
voltmeter (DVM) will now measure the Line to Earth voltage. This
should be equal to the nominal Phase-Neutral voltage.
7. Test between the main neutral conductor and both line and load side of all
circuit protective devices. The test lamps should not light, proving there
is no supply at the circuit protective devices with the main switch/s in the
"OFF" position.
8. Replace the main neutral conductor and main earthing conductor into the
neutral link.
9. Turn the main switch ON.
NOTE: A similar polarity test sequence is required for sub-mains.
NOTE: Replacement of the main earth and neutral into the neutral
link at this time is to minimise the possibility of a potential rise
on the earthing system during tests and causing others on site to
receive a shock.
10. Test between the main neutral conductor and the line side of all circuit
protective devices (CPD's) – proves supply at CPD's (half glow).
11. Test between the phases of circuit protective devices (line side) on a
multiphase installation (full glow).
12. Test between the main neutral conductor and the load side of any circuit
breakers. Test lamps should not light proving the CBs turn off (no-glow).
13. Turn on all CBs and test the load side of all CBs. Lamps should light proving
CBs turn on (half glow).
14. Reinstate any service bonding conductor that was removed.
GL McGavin ModieLamp Manual Page : 9
1. Connect the ModieLamp to any 2 phases. Ensure that both the green and
orange phase rotation indicator neon lamps light up.
2. Connect lead provided to 4mm socket labelled L2. Connect all 3 connections
in the appropriate sequence, e.g.. L1 to Aø (Red phase)ø, L2 to Bø (White
phase), L3 to Cø (Blue phase).
A Green indication shows normal (correct) phase sequence.
An Orange indication shows reversed (incorrect) phase sequence
Using the ModieLamp for Continuity Testing:
If a purpose built continuity tester is not readily available, the ModieLamp
together with the ModieProve can be used together as a Continuity Tester by
connecting them in series as shown. If continuity is established, the ModieProve
LED and audible alarm will activate.
