Frequently Asked Questions - TPT320 Megger

How to test continuity with the TPT320?

Make sure the circuit is not live. Connect both probes. The continuity LED lights up and the buzzer sounds continuously for resistance below 500 kΩ. No value is displayed on the LCD screen.

How to measure AC or DC voltage?

Connect both probes to the circuit. The voltage is indicated by the LEDs and the value appears on the LCD screen. The buzzer sounds above approximately 38 V AC or 100 V DC. Polarity is shown by the + or - LEDs.

What does the display 'OL' mean?

The 'OL' (Over Load) display indicates that the measured voltage exceeds 690 V. The tester should not be used beyond this limit.

How to check the battery status?

Perform a self-test by short-circuiting the test probes. If the continuity LED lights up and a beep sounds, the batteries are sufficient. If the low battery indicator appears on the LCD screen, replace the batteries with two AAA 1.5 V batteries.

How to replace the batteries?

Remove the probes from any circuit. Unscrew the battery cover, replace the used batteries with two AAA/LR03 1.5 V batteries observing polarity, then screw the cover back on.

What safety precautions should be observed?

Do not use the device in a humid environment. Always check the tester on a known voltage source before and after use. Keep your hands behind the protective barriers. Do not use the device if the housing is damaged or if batteries are leaking.

How to test phase rotation?

Hold the tester and the remote probe firmly, hands behind the barriers. Connect both probes to a 4-wire three-phase system. The R LED indicates a right rotating field, the L LED a left rotating field.

What if the flashlight does not turn on?

Press the flashlight switch. If it does not turn on, check the batteries. The flashlight turns off automatically after approximately 10 seconds.

How to test a diode with the TPT320?

Connect probe L1 (-) to the anode and L2 (+) to the cathode. The continuity LED lights up and the buzzer sounds. Reverse the connections: no signal indicates a functional diode.

How to clean and maintain the TPT320?

Keep the device clean and dry. Do not use solvents. Store it in a dry place at room temperature. Remove the batteries if the device is not used for an extended period.

Before commencing any testing, short the prods together to check the batteries.

The TPT320 is designed to offer a high degree of safety. It conforms to standards DIN VDE 0682-401 and IEC/EN 61243-3.

To ensure that the unit is operated safely, please read the following instructions before using the device.

■ Do not use the instrument in a humid environment.
■ Before testing a live circuit the voltage tester should be checked by connecting to a known voltage source (e.g. a suitable 120 / 230 V outlet or a suitable proving unit) before and after use.
■ Tests for voltage should be made with both poles.
■ Extreme care must be conducted when testing voltages above 50 V AC / 120 V DC.
■ Ensure the tester is only used within the stated measurement ranges and in low voltage installations up to 690 V and in the measuring category it has been designed for.
■ When testing ensure hands are behind the barriers on the main body and remote probe. Avoid touching the tips.
■ The instrument must be in good order, clean, dry and with no broken case or damaged lead or probes.
- Do not use the unit with battery cap removed and ensure when changing the batteries no probe is connected to any circuits.
■ Do not use the instrument if one or more functions are not working correctly.
■ The voltage warning triangle LED will illuminate to indicate voltage is present at the tips in the event of exhausted batteries while testing. This must not be used for measuring purposes.
■ The audible indication should be considered for audibility in noisy environments.
■ Remove the batteries if the tester is not to be used for a long period of time.
■ The voltage tester must not be used with exhausted or leaked batteries. Danger of electric shock!

General point: Voltage tests have priority on the TPT320. If no voltage is detected at the probe tip (<10 V), the device is in continuous test mode.

Introduction

The Megger TPT320 voltage tester provides electricians and electrical engineers with voltage indication but has additional functions / features that makes the instrument more versatile.

The TPT320 features both LCD and LED displays that provide AC and DC voltage measurement from 12 to 690 volts, in addition, a continuity function ranging from 0 to 500 kΩ. Continuity and voltage measurements are accompanied by an acoustic sounder.

A bright LED torch feature allows safe working in poorly lit environments.

When conducting a test between phase and earth on a circuit protected by an RCD, RCBO and Safety Breaker the TPT320 will not trip these devices.

The phase rotation indication feature is simplified which avoids the crossing of the test probes adopted by some 2 pole testers.

With safety in mind, the TPT320 is CAT IV 600 V rated with an IP64 rated strong body that provides an easy and comfortable grip. GS38 shrouds are provided as standard.

The unit has a feature that will warn the operator of dangerous test voltages even when the batteries have become exhausted.

Please note: To comply with GS38 (minimum exposed tip) the metal caps on each prod must be unscrewed and replaced with the supplied plastic tip shrouds.

Operating instructions

Auto-power-on / switching on

The tester switches on when it detects continuity, an AC or DC voltage above approx. 10 V or a live phase on L2 (single pole test). It can also be switched on with the torch light button.

Auto-power off

Tester is automatically powered off after 5 sec when there is no signal detected by the probes. The torch light switches off after approx. 10 sec.

Self test

Before commencing any measurements with the TPT320 a self test should be made. Short the probes tips together; the continuity LED will illuminate and a continuous audible tone will be heard. This procedure checks the batteries have sufficient power to operate the voltage tester correctly.

CAUTION: This test does not indicate the tester is capable of indicating correct supply voltage; a known live supply or a dedicated proving unit should be utilised to check the voltage measuring capability of the unit before and after testing.

If only the voltage warning LED illuminates (>50 VAC / >120 VDC) and the LCD display is blank then check the batteries.

(This feature must not be used as a means of continuing voltage indications.)

If the low battery indicator appears in the LCD window then change the batteries.

Continuity test

Ensure the circuit under test is not energised. Connect both test probes to the circuit. The continuity LED illuminates and buzzer sounds continuously to indicate continuity < 500 kΩ. Note: No continuity measurement is available on the LCD display.

Diode test

Connect the L1 - probe to the anode of the diode and the L2 + probe to the cathode. The continuity LED will illuminate and the buzzer will sound. Reversing the connections, the continuity LED will not illuminate and no sound will be present.

AC/DC Voltage test

690 VAC DC 400 230 120 50 24 12 + - Rx L R 235.2

690 VAC DC 400 230 120 50 24 12 + - Rx L R 120.0

Connect both probes to the circuit under test. The voltage is indicated by LEDs and the LCD display.

The buzzer sounds when a threshold voltage of approximately 38 VAC or approximately 100 VDC is exceeded.

Voltage polarity is indicated in following manner.

AC: Both + and - 12 V LEDs are on.

+DC: +12 V LED is on.

-DC: -12 V LED is on.

When the L2 probe + is the positive (negative) potential, the Polarity indication LED indicates "+DC" ("-DC").

During a voltage test, L or R LEDs may illuminate.

For voltages over 690 V the LCD will display 'OL'.

Single-pole phase test

690 VAC DC 400 230 120 50 24 12 + - Rx L R

Hold the tester securely in your hand. Connect the "L2+" probe to the object under test.

Voltage warning LED lights up and buzzer sounds when a voltage of approximately 100 V AC or more exists in the object under test.

(Pol ≥ 100 VAC)

Function of this test may not be fully achieved if the insulation condition / grounding conditions of user or of the equipment under test are not good enough.

Note: Verification of live-circuits should not be dependent on a Single-pole phase test only.

Phase rotation test

690 VAC DC 400 230 120 50 24 12 + - Rx L R 4 152

690 VAC DC 400 230 120 50 24 12 + - L R Rx 4 15.2

L LED and R LED's for the Phase rotation test may operate on various wiring systems, but an effective test result can only be obtained on three-phase 4-wire systems.

Hold the tester and remote probe firmly in each hand, ensuring hands are behind the hand barriers, and connect both probes to the object under test. Phase-to-phase voltage is indicated by voltage LEDs and LCD display.

R LED lights up for Right rotary field. (L1, L2, L3)

L LED lights up for Left rotary field. (L1, L3, L2)

Measurement principle: The instrument detects the phase rising order referencing the user as earth. The function of this test may not be fully achieved if the insulation condition/ grounding conditions of user or of the equipment under test are not good enough.

Torch light

Pressing the torch light button will turn on the light and after approximately 10s it will turn itself off.
