4. Product description

The multitester MS18-2 is the further technical development of the successful MS 18. Next to the functions of the MS-18 the MS 18-2 has also been equipped with power saving measuring electronics, through which the current consumption could be lowered by 70 percent. MS18-2 furthermore has a temporary memory function which delays the LEDdisplayafurther0.5to2secondsinordertoachievepreciseanddenitemeasuringresults. With the MS 18-2 you can check voltage-carrying electric lines and part, whether alternating voltage is applied. This can be carried out either with direct contact or contactless (indirect). The indirect measuring can be especially helpful with insulated lines and parts. Moreover, the polarity of direct voltage sources can be determined. When using the device as a continuity tester for circuit track conductors, chassis earth connections, fuses, power cords, light bulbs, switches and many more can be tested on their function (continuity) when off circuit. A further area of use is the test- ingofcomponentssuchasdiodes,rectiers,condensers,transistors(NPN/PNP),coils,etc.butalsothetestingof microwaves for leakage. The display is via a built-in red LED.

6. Safety instructions

In the case of any damages which are caused due to failure to observe these operating instructions, the guarantee will expire. We do not assume liability for resulting damages. An exclamation mark inside a triangle points to important notes in the operating manual. Please read through the entire manual before putting the device into operation.

• Theunauthorisedconversionand/ormodicationoftheMS18-2isnotpermittedbecauseofsafetyand approval reasons.

• Never exceed the maximum input quantities.

• A reliable display is only ensured at a temperature range of –10 °C to +50 °C and a frequency range of 50 Hz to 500 Hz. The tester is only authorized for the use in closed and dry rooms.

• Avoid all contact to dampness

• Never use the tester if there are any visible damages. Before each use the device needs to be checked if it works correctly.

• Incommercialandindustrialfacilitiestheregulationsforthepreventionofaccidentsoflaiddownbythe professional trade association for electrical equipment and devices need to be observed.

• Static electricity e.g., caused by strong rubbing on the plastic housing, can falsify the reading.

• This tester should be kept out of reach of children.

• The multitester is not suitable to be used as a screwdriver. Be especially careful with voltages larger than 25 V AC or 35 V DC. With voltages like this you can already suffer a life-threatening electric shock.

• This tester can only be used in electrical circuits which are protected with 10A (and/or no capacities largerthan4000VAappear).Inthecaseofanyquerieswhichcouldnotbeansweredbytheseoperating instructions, please a consult specialist or contact our customer service by phone.

7. Description of individual components

a) Inserting the battery / Changing of battery To operate the multitester two round cell batteries type 392A, AG3, LR41, 192 (or identically constructed) are needed. To avoid an electric shock the multitester must not be operated when open. After each battery change a self-test needs to be carried out. To change the batteries you need to:

• Open the battery compartment at the end of the grip with a suitable screwdriver (3). Opening = turn left (anti- clockwise). Also see illustration below.

• Take out the battery compartment lid (3). Carefully bend back the wire clip which holds the round cell batteries.

• Now take out the empty round cell batteries and replace them with two new others of the same type. Take care to observe the polarity of the round cell batteries.

• Carefully bend back the wire in its original position.

• Put the screw back into the device. Carefully tighten the screw. Closing = turn right (clockwise).

Please check the device for damage(s) such as e.g., breaks on the housing etc. Touch the tip (1) of the tester with one hand and at the same time touch the battery compartment lid (3) with the other hand. When the red LED (2) starts blinking, the multitester is in working order and can be used. In case the red LED does not blink, the device must not be used. If necessary change the batteries.16 c) Alternating voltage detection 1Direct contact (70 to 250 V alternating voltage) Touchtheelectricconductor(phase)withthemeasuringtip(1).IftheLED(2)lightsup,thereisvoltage.

Please note that the LED (2) only goes out after approx. 0.5 to 2 seconds after removing the device from the voltage because of the temporary memory function. Guide the measuring tip of the MS18-2 along an electric cable, electrical outlet or the device.

Caution! Microwave radiation is dangerous. This tester can not be compared with a high-tech device. The cost for measuring devices like this are much larger. This is why you should see this test only as an indication for possibly existing microwave radiation.

• Switch your microwave on

• Touch the battery compartment lid (3) with one hand and guide the test tip of the multitester slowly along the door ofthemicrowave.Ifthedoorsealisleaky,theLEDwillstartblinking.If this is the case, the microwave must not be operated anymore. Take the device to a specialist.
