Laserliner 083 028 Multi Meter Pocket Box

Read the operating instructions and the enclosed brochure „Guarantee and additional notices“ completely. 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 overvoltage category CAT III up to max. 300 V. The meter can be used to measure DC and AC voltages and direct and alternating currents within the specified ranges, as well as for continuity and diode testing.

Symbols

Hazardous electrical voltage warning:
Unprotected live components inside the device and the housing may pose a risk of electric shock.
Danger area warning
Protection class II: The test device has reinforced or double insulation.
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.

Safety instructions

• The device must only be used in accordance with its intended purpose and within the scope of the specifications. Modifications or changes to the device are not permitted, this will otherwise invalidate the approval and safety specifications.

• In overvoltage category III (CAT III), the voltage between the tes device and earth must not exceed 300 V.

• Do not expose the device to mechanical stress, extreme temperatures or significant vibration.

• 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.

• 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.

• 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 isolated from all current sources 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.

• Disconnect the power supply to the electrical circuit before measuring or checking the diodes, resistance or battery charge. Make sure that all high-voltage capacitors are discharged.
  To check, remove the measuring leads of the device from
  the test piece before changing the mode.

• When connecting to a voltage, always connect the black measuring lead first before the red lead. Follow the reverse procedure when disconnecting.

• If possible, do not work alone. Carry out measurements in
  the vicinity of hazardous electrical installations only under the guidance of a qualified electrician.

• The measuring tools and accessories are not toys.
  Keep out of reach of children.

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.

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.

Insertion of batteries / Replacing the fuse

Isolate the device from all current sources before opening the battery compartment cover. Do not switch on the device with the cover open.

Do not touch the green pc-board. Also make sure it is kept clean.

Voltage measurement DC/AC

To take a voltage measurement, turn the rotary switch to position   Then connect the measuring contacts to the object to be tested. The measured value acquired and the polarity appear on the display.

Voltage measurement AC

To take a voltage measurement, turn the
rotary switch to position  Then connect the measuring contacts to the object to be tested. The measured value acquired and the polarity appear on the display.

Resistance measurement

To measure the resistance, turn the rotary switch to position „Ω“.
Then connect the measuring contacts to the object to be tested. The measured value acquired appears on the display. If „O.L.“ appears on the display instead of a measured value, either the measuring range has been exceeded or the measuring circuit is not closed or has been interrupted. Resistances can only be measured correctly in isolation; therefore, the components might need to be disconnected from the remainder of the circuit.

Note: When measuring resistance, to avoid the risk of the results of a measurement being distorted, there must be no traces of dirt, oil, solder spray, or other contamination on the test prods.

Continuity test

To test continuity, turn the rotary switch to position and press the „Mode“ switch once to activate the „Continuity test“ function.
Then connect the measuring contacts to the object to be tested. A measured value of < 30 ohms is recognised as continuity; this is confirmed by an audible signal. If „O.L.“ appears on the display instead of a measured value, either the measuring range has been exceeded or the measuring circuit is not closed or has been interrupted.

Diode test

To test the diode, turn the rotary switch to position
Then connect the measuring contacts to the diode. The measured value acquired for the forward voltage appears on the display. If „O.L.“ appears on the display instead of a measured value, the diode has either been tested in the reverse direction or is faulty.

Current measurement DC/AC

To take a current measurement in the range from 0 to 200 mA, turn the rotary switch to position „mA“ and press the „Mode“ button to set the voltage mode (AC, DC). Disconnect the circuit before connecting the meter. Then connect the measuring contacts to the object to be tested. The measured value acquired and the polarity appear on the display. Disconnect the circuit again before disconnecting the meter.

Note: No currents above 200 mA may be measured in the μA/mA range! Currents above this level trigger the automatic fuse in the meter (fuse 250 mA/300 V quick blow, Ø 5 mm x 20 mm).

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.
