Frequently Asked Questions - ActiveMaster Digital Laserliner

How to install batteries in the ActiveMaster Digital tester?

Open the battery compartment cover (mark 12) and insert 2 AAA 1.5 V batteries (LR03, alkaline) respecting polarity. Once batteries are installed, the device is immediately operational. It does not have a separate On/Off switch.

How to perform the self-test?

Connect the test probes (1) and (2): the continuity test LED (13) should light up and a beep sounds. Then press the 'AUTOTEST' button: if all LEDs light up and a signal sounds, the self-test is successful.

How to measure voltage with the tester?

Attach the protective caps for CAT III 1000 V or CAT IV 600 V if necessary. Hold the (+) test probe in the right hand and the (-) probe in the left hand. Place the probes on the contacts to test. The device activates automatically for voltages >4.5 V and displays the numerical and bar graph value.

How to check for phase presence (single-pole test)?

Leave the L1 probe free. Touch the conductor to test with the L2 probe. In the presence of AC voltage (approx. 100 V AC min.), the phase display LED (9) lights up. This test requires good batteries. It does not replace a two-pole test to verify absence of voltage.

How to determine the direction of rotating magnetic field?

Connect the L1 and L2 probes to the assumed conductors. If the symbol R (right) appears, the phases are correctly identified. If the symbol L (left) appears, reverse the probes. Perform a cross-check by reversing the probes for confirmation.

What to do if the device does not turn on or does not measure?

Check that the batteries are correctly inserted and in good condition. Test the device on a known voltage source (230 V outlet or battery). If the continuity test (probes shorted) does not work, the batteries may be discharged or the device may be defective.

How to clean and maintain the tester?

Before each use, clean and dry the instrument. Use a dry cloth. Avoid moisture, condensation, and conductive residues. Calibration is recommended once a year to ensure accuracy.

What are the safety risks to know?

Voltage above 25 V AC or 60 V DC can be lethal. Never work alone near dangerous electrical installations. Do not keep the probes in contact for more than 30 seconds. Always use the appropriate overvoltage category (CAT II/III/IV).

How to interpret the polarity display?

The polarity display (4) indicates the sign of the measured voltage: '+' for positive polarity, '-' for negative. This works over the entire voltage range for DC.

What do the overvoltage categories CAT II, CAT III, and CAT IV mean?

CAT II applies to devices plugged into household outlets (single-phase). CAT III applies to fixed installations (distribution boards). CAT IV applies to the power source (meters, circuit breakers). The device comes with protective caps to switch from CAT II to CAT III/IV.

Read the operating instructions and the enclosed brochure „Guarantee and additional notices“ completely. Follow the instructions they contain. Safely keep these documents for future reference.

Function/Application

Voltage and continuity tester for automatic measurement of AC (alternating current) and DC (direct current) voltages. The device can be used to perform a single-phase test and a rotating field test while also indicating the phase direction. The information is indicated by means of an LED display and an acoustic signal.

Safety instructions

• The device must only be used in accordance with its intended purpose and within the scope of the specifications.
• Before every measurement make sure that the area to be checked (e.g. line) and the tester are in perfect operating condition. Test the device by connecting it to known voltage sources (e.g. a 230 V socket in the case of AC testing or a car battery in the case of DC testing). Stop using the device if one or a number of its functions fails.
• If you are working with voltages higher than 25 V AC/60 V DC, exercise extreme caution. Touching the electrical conductors at such voltages poses a risk of life-threatening electric shocks. Take particular care if the 50V warning LED is on.
• Do not use the device in environments in which there are conductive particles or where the occurrence of moisture (in the form of condensation, for example) can create transient conductivity.
• If the device comes into contact with moisture or other conductive residue, work must not be carried out under voltage. At and above voltages of 25 V AC/60 V DC, the presence of moisture creates the risk of life-threatening electric shocks. Clean and dry the device before use. When using the device outdoors, make sure that the weather conditions are appropriate and/or that suitable protection measures are taken.
• If you are taking measurements in the hazardous vicinity of electrical installations, do not work alone and seek guidance from an electrically skilled person before starting work.

AC-tiveMaster Digital

• Isolate the device from all current sources before opening the battery compartment cover.
• The device must not be connected to voltages for longer than 30 seconds.
• Hold the device by the grip sections only. Do not touch the test prods during measurement.
• If possible, do not work alone.
• Use the device only in the correct overvoltage category (without protective cover CAT II 1000 V; with protective cover CAT III 1000 V + CAT IV 600 V)

Symbols

Hazardous electrical voltage warning: Unprotected live components inside the device housing may pose a risk of electric shock.

Danger area warning

Protection class II: The test device has reinforced or double insulation.

CAT II

Overvoltage category II: Single-phase consumers that are connected to standard sockets, e.g. household appliances, portable tools.

CAT III

Overvoltage category III: Equipment in fixed installations and for applications where specific requirements with regard to the reliability and availability of equipment have to be met, e.g. circuit-breakers in fixed installations and devices used in industrial applications which are permanently connected to the fixed installation.

CAT IV

Overvoltage category IV: Devices such as electricity meters, overcurrent circuit breakers and ripple-control units, which are intended for use at or near the infeed into the electrical installation of buildings, and specifically from the main distribution to the supply system.

1 Insertion of batteries

The device is ready for use immediately once the batteries have been inserted. It does not have a separate ON/OFF switch and is therefore always active. As from a measuring voltage of 50 V, the device operates in emergency mode even without batteries.

• Test the voltage tester by applying it to familiar voltage sources
• Connect test prods (1) and (2). The LED for the continuity test (13) lights up and a signal sounds.
• Press the „AUTOTEST“ button. On successful completion of the test, the LEDs for the continuity test (13) as well as all segments of the bar graph light up and a signal sounds.

3 Voltage test

!

To achieve the protection class CAT III 1000 V and CAT IV 600 V the protective covers must be placed over the test prods.

Close-up of a syringe injecting liquid into an electrical outlet (no visible text or symbols)

Hold the base device (+) in your right hand and the second test prod (-) in your left hand. Now apply the test prods to the contacts to be tested (line, socket, etc.).

- The voltage tester is automatically active as from a voltage of >4.5 V and shows the measured voltage both numerically and as a bar graph.

4 Single-pole phase test

- Make contact with the conductor to be tested with test prod L2, L1 remains free during the measurement. The LED (9) will light up if an AC voltage is applied on the conductor.

- The single-pole phase test can only be performed with fully charged batteries inserted.

- The single-pole phase test can be carried out as from an AC voltage of approx. 100 V AC.

- When the single-pole phase test is carried out on the outer conductor, the indicator function may be adversely affected under certain conditions (e.g. when insulating personnel protective equipment is used or at insulated locations).

!

The single-pole phase test is not suitable for checking for zero voltage. To do this, you need to carry out a two-pole phase test.

5 Determining the direction of the rotating field

Clockwise rotating fieldAAnticlockwise rotating field

If the symbol R (7) appears in the display, this means that the presumed phase L1 is actually phase L1 and the presumed phase L2 is actually phase L2.

If the symbol L (7) appears in the display, this means that the presumed phase L1 is actually phase L2 and the presumed phase L2 is actually phase L1.

!

When you crosscheck this by switching round the test prods, the opposite symbol should light up instead.

6 Battery lamp

To switch on the battery lamp, press and hold down button 10. The light switches itself off automatically as soon as the button is released.

7 Calibration

The voltage tester needs to be calibrated and tested on a regular basis to ensure it produces accurate measurement results. We recommend carrying out calibration once a year.
