Safety Precautions

This product complies with the requirements of the following European Community Directives:
2014/30/EU (Electromagnetic Compatibility) and 2014/35/EU (Low Voltage) as amended by
2014/32/EU (CE-Marking).
Overvoltage category III 1000V; pollution degree 2.
CAT I: For signal level, telecommunication, electronic with small transient over voltage
CAT II: For local level, appliances, main wall outlets, portable equipment
CAT III: Supplied from a cable under earth; fixed installed switches, automatic cut-off or main plugs
CAT IV: Units and installations, which are supplied overhead lines, which are stand in a risk of persuade of a lightning, i.e. main-switches on current input, overvoltage-diverter, current use counter.
To ensure safe operation of the equipment and eliminate the danger of serious injury due to shortcircuits  (arcing), the following safety precautions must be observed.
Damages resulting from failure to observe these safety precautions are exempt from anylegal claims whatever.

• Never touch the probe tip while operating insulation test Do not use this instrument for high-energy industrial installation measurement. This instrument is intended for use in installation over voltage category III.
• Do not place the equipment on damp or wet surfaces.
• Do not exceed the maximum permissible input ratings (danger of serious injury and/or destruction of the equipment).
• The meter is designed to withstand the stated max voltages. If it is not possible to exclude without that impulses, transients, disturbance or for other reasons, these voltages  are exceeded a suitable presale (10:1) must be used.
• Disconnect test leads or probe from the measuring circuit before switching modes or functions.
• To avoid electric shock, disconnect power to the unit under test and discharge all capacitors before taking any resistance measurements.
• Check test leads and probes for faulty insulation or bare wires before connection to the equipment.
• Please use only 4mm-safety test leads to ensure immaculate function.
• To avoid electric shock, do not operate this product in wet or damp conditions. Conduct measuring works only in dry clothing and rubber shoes, i. e. on isolating mats.
• Never touch the tips of the test leads or probe.
• Comply with the warning labels and other info on the equipment.
• The measurement instrument is not to be to operated unattended.
• Always start with the highest measuring range when measuring unknown values.
• Do not subject the equipment to direct sunlight or extreme temperatures, humidity or dampness.
• Do not subject the equipment to shocks or strong vibrations.
• Do not operate the equipment near strong magnetic fields (motors, transformers etc.).
• Keep hot soldering irons or guns away from the equipment.
• Allow the equipment to stabilize at room temperature before taking up measurement (important for exact measurements).
• Do not input values over the maximum range of each measurement to avoid damages of the meter.
• Do not turn the rotary function switch during voltage or current measurement, otherwise the meter could be damaged.
• Use caution when working with voltages above 35V DC or 25V AC. These Voltages pose shock hazard.
• Replace the battery as soon as the battery indicator “BAT” appears. With a low battery, the meter might produce false reading that can lead to electric shock and personal injury.
• Fetch out the battery when the meter will not be used for long period.
• Periodically wipe the cabinet with a damp cloth and mid detergent. Do not use abrasives or solvents.
• The meter is suitable for indoor use only.
• Do not operate the meter before the cabinet has been closed and screwed safely as terminal can carry voltage.
• Do not store the meter in a place of explosive, inflammable substances.
• Do not modify the equipment in any way.
• Do not place the equipment face-down on any table or work bench to prevent damaging the controls at the front.
• Opening the equipment and service – and repair work must only be performed by qualified service personnel
• Measuring instruments don’t belong to children hands.

Cleaning the cabinet
Clean only with a damp, soft cloth and a commercially available mild household cleanser. Ensure that no water gets inside the equipment to prevent possible shorts and damage to the equipment.
CAUTION!
Note on using the supplied safety test leads according the IEC / EN 61010-031:2008:
Measurements in the field of overvoltage category CAT I or CAT II can be performed with test leads without sleeves with a maximum of up to 18 mm long, touchable metallic probe, whereas for measurements in the field of overvoltage category CAT III or CAT IV test leads with put on sleeves, printed with CAT III and CAT IV must be used, and therefore the touchable and conductive part of the probes have only max. 4 mm of length.

Precautions & Preparation for Measurements

1. Remove the power from the circuit when making the measurement. If any voltage is present in the testing circuit, then an erroneous reading will result.
2. Ensure, that the batteries (6 x 1,5 V AA battery) are connected correctly to the right position into the battery compartment.
3. Rotate the “Function-/Range Switch” to the right position before making measurement.
4. Slide the “Range/Funktion Switch” to the off position if the meter is not used.

Measuring Procedure

6.1. Ohms Measurement (Continuous Check)

1. Connect the RED test plug into V/Ω-jack.
2. Connect the BLACK test plug into COM-jack. 3. Rotate the Function/Range Switch to the “400 ” position.
3. Connect test leads into circuit under test.
4. Read the measured values at the display.

6.2. MegOhm Measurement (Insulation Measurement)
Attention! Never touch the tips of the test leads while insulation measurement.

1. Connect the RED test plug into the V/Ω-jack.
2. Connect the BLACK test plug into the COM-jack.
3. Rotate the Function/Range Switch to the position according the user´s requirement.
4. Connect test leads into circuit under test.
5. Push the Test Button for measurement.

6.3. Continous Insulation measurement

1. Press the Lock/Continous button, until a lock symbol appears at the display.
2. Push the Test button to start the Insulation measurement.
3. Push the Test button again to end the insulation test.

6.4. ACV Measurement

1. Connect the RED test plug into V/Ω-jack.
2. Connect the BLACK test plug into COM-jack-
3. Rotate the Function/Range Switch to the 750 V AC position.
4. Connect test leads into circuit under test.
5. Read the measured values at the display.

6.5. Measuring Consideration for Meg Ohm Testing

1. The amount of time during which the test voltage applied will also affect the reading. With good insulation, the measured value of insulation resistance will slowly increase is applied typically. This is due to the electric absorption effect of the applied DC voltage on the bulk insulation resistance.
2. Measurements made in a humid environment will result in lower insulation resistance values than a dry environment.

Battery Replacement

1. When the upper left corner of LCD Display shows “BAT”, it is necessary to replace the battery. However in-spec measurement may still be made for several hours after LOW BATTERY INDICATOR appears before the instrument becomes inaccurate.
2. Loose the screws on the battery cover, slide the battery cover & remove the battery.
3. Replace with 6 x 1,5 V AA (UM-3) battery and reinstate the cover.

ATTENION !
Batteries, which are used up dispose duly. Used up batteries are hazardous and must be given in the for this supposed collective container.
7.1. Notification about the Battery Regulation
The delivery of many devices includes batteries, which for example serve to operate the remote control. There also could be batteries or accumulators built into the device itself. In connection with the sale of these batteries or accumulators, we are obliged under the Battery Regulations to notify our customers of the following:
Please dispose of old batteries at a council collection point or return them to a local shop at no cost.  The disposal in domestic refuse is strictly forbidden according to the  Battery Regulations. You can return used batteries obtained from us at no charge at the address on the last side in this manual or by posting with sufficient stamps.
Contaminated batteries shall be marked with a symbol consisting of a crossed- out refuse bin and the chemical symbol (Cd, Hg or Pb) of the heavy metal which is responsible for the classification as pollutant:

1. “Cd” means cadmium.
2. “Hg” means mercury.
3. “Pb” stands for lead.

Cleaning and storage:
Periodically wipe the case with a damp cloth and detergent. Do not use abrasives or solvents.
If the meter is not to be used for periods of longer than 60 days, remove the batteries and store them separately.
