SAFETY INFORMATION

• Ensure that user is competent, qualied and authorised to carry

out the required work.

• Avoid working alone.

• Do not use the ModieLamp in wet conditions, or around explosive

gas or vapour.

• Use the ModieLamp only as specied in this manual.

• When using test leads or probes keep your ngers behind the

nger guards.

• Only use leads and probes supplied with the unit.

• Use extreme caution when working around bare conductors or

busbars. Contact with conductors can result in both electric shock
and possible electrocution.

• Use caution with voltages above 30VAC RMS. This voltage poses a

shock hazard.

• Comply with local and national safety requirements when working

in hazardous locations.

• Use only the replacement fuse specied or the protection may be

impaired.

• Always check ModieLamp prior to use.

Description

The ModieLamp comprises of three sections:

• A test lamp set.

• A specially designed digital voltmeter (DVM), and

• A phase sequence indicator.

Features:

• Low input impedance DVM providing immunity to 'phantom' voltages.

• Phase sequence testing.

• Dangerous voltage alarm, (inception voltage and alarm mark/space ratio can

be factory adjusted to meet customer requirements).

• 4.5-digit 6000 count LCD resolution.

• Advanced electronic chip-set providing high accuracy true RMS readings.

• Peak voltage capture mode.

• Hold voltage reading mode.

• Immune to DC voltage components.

• Multiple lead and probe combinations available. Can be further tailored to

meet customer requirements.

• LCD back-light option.

Intended Use:

• Modielamp’s intended use is as a set of test lamps for low voltage neutral

and phase identication (polarity testing) on three phase (3ø) and single
phase (1ø) systems, overhead lines and underground cables, and for general
electrical installation testing and fault-nding.

• The digital voltmeter (DVM) can test voltage from 0.0VAC to 600.0VAC true

RMS.

• Phase sequence on 415VAC 3ø systems can be identied by connecting a

fused third lead (provided) to the unit.

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.
