Completely read through the operating instructions, the „Warranty and Additional Information” booklet as well as the latest information under the internet link at the end of these instructions. Follow the instructions they contain. This document must be kept in a safe place and passed on together with the device.

Function/Application

Multimeter for taking measurements in the range of the overvoltage category CAT III up to max. 1000 V/CAT IV up to max 600 V. The meter can be used to measure DC and AC voltages, direct and alternating currents, resistances, capacitances, frequencies and duty factors within the specified ranges; it can also be used for continuity and diode testing.

Symbols

Hazardous electrical voltage warning: Unprotected live components inside the devicehousing 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.

Safety instructions

• The device must only be used in accordance with its intended purpose and within the scope of the specifications.
• The measuring tools and accessories are not toys. Keep out of reach of children.
• Modifications or changes to the device are not permitted, this will otherwise invalidate the approval and safety specifications.
• Do not expose the device to mechanical stress, extreme temperatures or significant vibration.
• Exercise extreme caution when working with voltages higher than 24 V/AC rms or 60 V/DC. Touching the electrical conductors at such voltages poses a risk of life-threatening electric shocks.
• If the device comes into contact with moisture or other conductiveresidue, work must not be carried out under voltage. At and above voltages of 24 V/AC rms / 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.

• In overvoltage category III (CAT III - 1000 V), the voltage between the test device and earth must not exceed 1000 V.

• In overvoltage category IV (CAT IV - 600 V), the voltage between the test device and earth must not exceed 600 V.

• The lowest overvoltage category (CAT), rated voltage and rated current apply when using the device together with the measuring equipment.
• Before taking any measurements, make sure that both the area to be tested (e.g. a line), the test device and the accessories used (e.g. connection cable) are in proper working order. 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).
• The device must no longer be used if one or more of its functions fail or the battery charge is weak.
• The device must be disconnected from all power sources and measuring circuits before opening the cover to change the battery(ies) or fuse(s). Do not switch on the device with the cover open.
• Observe the safety precautions of local and national authorities relating to the correct use of the device and any prescribed safety equipment (e.g. electrician's safety gloves).
• If you have to take hold of the measuring spikes, do so by the grip sections only. Do not touch the measuring contacts whilst the measurement is being taken.
• Make sure that you always select the correct connections and rotary switch position with the correct measuring range for the measurement to be carried out.
• Do not work alone in the vicinity of hazardous electrical installations and only under the guidance of a qualified electrician.
• Disconnect the power supply to the electrical circuit before measuring or checking the diodes, resistance or battery charge.
• Check that all high-voltage capacitors are discharged.
• When connecting to a voltage, always connect the black measuring lead first before the red lead. Follow the reverse procedure when disconnecting.
• Only the original measuring leads may be used. Their voltage, category and ampere rated powers must match those of the measuring device.

Additional information on use

Observe the technical safety regulations for working on electrical systems, especially: 1. Safely isolating from power supply, 2. Securing to prevent system being switched on again, 3. Checking zero potential, two-pole, 4. Earthing and short-circuiting, 5. Securing and covering adjacent live components.

The MAX/MIN/AVG function shows the highest, lowest and average measured values. The measured values are updated each time a higher or lower measurement is recorded. To activate the function, briefly press the MAX/MIN/AVG button. „MAX“ appears together with the highest value on the LC display. By briefly pressing the MAX/MIN/AVG button, the device switches from MAX to MIN and from MIN to AVG. Keep the MAX/MIN/AVG button pressed to exit MAX/MIN/AVG function and return to normal operation.

18EAK function (voltage peak function)

The PEAK function detects the highest positive and lowest negative peak in an AC voltage or AC current wave form. The measured values are updated each time a higher positive or lower negative PEAK is detected.

Activate PEAK "Peak MAX"

"Peak MAX" Highest positive peak

Switch to "Peak MIN"

"Peak MIN" Lowest negative peak

Briefly keep the PEAK button pressed to switch between Peak MAX and Peak MIN. To return to normal operation, keep the PEAK button pressed until Peak on the LC display disappears.

Information on maintenance and care

Clean all components with a damp cloth and do not use cleaning agents, scouring agents and solvents. Remove the battery(ies) before storing for longer periods. Store the device in a clean and dry place.

Calibration

The meter 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.

Data transfer

The device features a Bluetooth®* function that enables wireless data transfer to mobile devices with a Bluetooth®* interface (such as a smartphone or tablet).

The system prerequisites for a Bluetooth®* connection are specified at http://laserliner.com/info?an=ble

The device can set up a Bluetooth ^® * connection with Bluetooth 4.0 compatible devices.

The range is set to a maximum distance of 10 m from the terminal device and greatly depends on the ambient conditions such as the thickness and composition of walls, sources of interference as well as the transmit / receive properties of the terminal device.

Bluetooth ^® must be activated after switching on the device as the measuring system or measuring device is designed for very low power consumption.

A mobile device can link up to the active measuring device via an app.

Application (app)

An app is required to use the Bluetooth®* function.

You can download the app from the corresponding stores for the specific type of terminal device:

Make sure that the Bluetooth®* interface of the mobile device is activated.

After starting the app and activating the Bluetooth ^® * function, a connection can be set up between a mobile device and the measuring device. If the app detects several active measuring devices, select the matching device.

This measuring device can be connected automatically the next time it is switched on.
