SAFETY
1. SAFETY INFORMATION
This multimeter has been designed in accordance with IEC-1010. This norm pertains to electronic measuring
instruments that belong to an overvoltage category (CAT II 300V and CAT I 600V)
Follow all safety and operating instructions to ensure that the meter is used safely and is kept in good running order.
Full compliance with safety standards can only be guaranteed when the buyer uses the test leads supplied with this
packaging. If necessary, they should be replaced with identical leads.
2. SAFETY SYMBOLS
MAINTENANCE
Before opening the case, always disconnect the test leads from all live circuits.
Avoiding fire risks : respect the specified voltage and current ratings when replacing the fuse (F 200mA / 250V)
(Quick acting)
Do not use the device unless all the covers are in place and securely fastened.
Do not apply abrasives or solvents to the meter. Use a damp cloth and mild detergent for cleaning purposes.
DURING USE
Important safety information, refer to the user manual.
Fuse should be replaced : the rating is specified in the manual.
Never exceed the limit value for protection. This limit value is listed separately in the specifications for each
range of measurement.
Do not touch unused terminals when the meter is linked to a circuit which is being tested.
Never use the meter with category I installations when measuring voltages that might exceed the safety margin
of 600V above earth ground.
Set the range selector at its highest position if the intensity of the tension or current to be measured is
completely unknown.
Disconnect the test leads from the tested circuit before rotating the range selector in order to change functions.
When carrying out measurements on a TV set or switching power circuits, always remember that the meter may
be damaged by any high amplitude voltage pulses at test points.
Always be careful when working with voltages above 60Vdc or 30Vac rms. Keep your fingers behind the probe
barriers at all times during measurement.
Before attempting to insert transistors for testing, always verify if the test leads have been disconnected.
Components should not be connected to the hFE socket while test leads are being used to execute voltage
measurements.
Never perform resistance measurements on live circuits.

Soldering station
SOLDERING STATION
INTRODUCTION
This soldering station is temperature-controlled: sophisticated circuitry regulates the temperature between 150°C
and 450°C.
The unit is a 48W soldering station with a temperature sensor in the ceramic heating element. The heating element
is supplied with the necessary power via a safe 24V transformer, while the bit is completely isolated from the mains.
The control circuitry ensures that devices sensitive to static charges cannot be damaged during the soldering
process. The included bit consists of a copper core that is protected by a steel coating.

Soldering station
WORKING TEMPERATURE
Turn on the complete unit with mains switch on the back, the power indication LED (11) should lit. A well-chosen temperature is essential for efficient soldering. Solder does not flow well when the temperature is too low and this leads to weak
soldering. The flux in the solder evaporates when the tem perature is too high, not giving the solder sufficient time to flow
and possibly damaging the components. The correct temperature and the correct soldering technique practically guarantee a good result. The most c ommon solder alloy consists of 60% of tin (Sn) and 40% of lead (Pb). New lead free solder
consists of 99.7% Tin (Sn) and 0.3% Copper (Cu) or 96% Tin (Sn) and 4% Silver (Ag). If the set temperature is rising, the
“heating LED” (7) will lit, as soon as the temperature is reached, the LED will blink.
For Lead containing soldering a tip temperature of about 250 to 350°C is recommended.
For Lead free soldering a tip temperature between 350 to 400°c is recommended.
It is advisable to use lead containing solder to repair lead containing solderings.
Make sure to turn the temperature control to OFF if the soldering station is not used for long time.
TIPS
ALWAYS KEEP THE SPONGE WET (water only).
Wipe the bit clean before use and keep the tip tinned when the device is not being used.
Prolonged use at high temperatures causes the bit to wear prematurely
Never clean the bit with a file or abrasive materials.
Corrosion on the bit can be removed with very fine emery cloth (600 – 800) or with isopropyl alcohol. Heat and tin
the bit immediately after cleaning
Remove and clean the bit after 20 hours of usage (or at least once a week) to avoid corrosion
Do not use corrosive flux or flux containing chlorine. Resinous flux is safe.
MAINTENANCE
Let the bit cool down before cleaning or replacing it. You can remove the bit by loosening the nut on the bit holder.
Clean the bit holder next by blowing into it forcefully. Do not forget to protect your eyes !
Put the bit back in place and tighten the nut. Wipe clean the rest of the iron and the soldering station with a damp
cloth. Do not use sol vents and make sure no liquid penetrates the housing of the device.

VEILIGHEID
1. VEILIGHEIDSVOORSCHRIFTEN
Deze multimeter werd ontworpen in overeenstemming met de IEC-1010-norm. Deze norm heeft betrekking op
elektronische meetinstrumenten die tot een overvoltagecategorie (CAT II 300V en CAT I 600V) behoren. Volg
nauwgezet alle veiligheids- en bedieningsvoorschriften op. Enkel dan houdt u uw multimeter bedrijfsklaar en kunt u
er zeker van zijn dat u hem op een veilige manier gebruikt.
U voldoet enkel aan de veiligheidsvoorschriften indien u de meegeleverde testsnoeren gebruikt. Zo nodig moet u ze
vervangen door de identieke snoeren.
2. VEILIGHEIDSSYMBOLEN
Belangrijke info i.v.m. de veiligheid, zie gebruikershandleiding.
Zekering vervangen : het type is vermeld in de handleiding.
ONDERHOUD
Voordat u de behuizing openmaakt, moet u controleren of er nog testsnoeren aangesloten zijn op schakelingen die
onder stroom staan.
Vermijden van brandrisico's : respecteer de maximale voltage- en stroomniveaus wanneer u de zekering vervangt (F 200mA /
250V - snelwerkend)
Gebruik de meter nooit met open batterijdeksel.
Reinig de meter enkel met een vochtige doek en een zachte detergent. Gebruik nooit agressieve schuur- of oplosmiddelen.
TIJDENS GEBRUIK
Overschrijd nooit de grenswaarden. Deze waarden worden telkens apart vermeld in de specificaties van elk meetbereik.
Raak geen ongebruikte ingangsbussen aan wanneer de meter gekoppeld is aan een schakeling die u aan het testen bent.
Gebruik de meter nooit voor categorie II-installaties wanneer u voltages aan het meten bent die de veiligheidsmarge
van 600V boven het massapotentiaal (kunnen) overschrijden.
Zet de bereikregelaar op de hoogste stand als de te meten spanning of stroom helemaal ongekend is.
Koppel de testsnoeren los van de geteste schakeling voordat u een andere functie kiest d.m.v. de keuzeschakelaar.
Wanneer u metingen uitvoert op een TV of een schakelende voeding, mag u niet vergeten dat een sterke stroomstoot
ter hoogte van de geteste punten de meter kan beschadigen.
Wees uiterst voorzichtig wanneer u werkt met voltages boven 60Vdc of 30Vac rms.Tijdens uw metingen moet u uw
vingers te allen tijde achter de meetpennen houden.
Voordat u transistors aansluit om ze te testen, moet u nagaan of alle testsnoeren wel degelijk losgekoppeld zijn.
Sluit nooit componenten aan op de hFE-connector terwijl u spanningsmetingen aan het uitvoeren bent d.m.v.
testsnoeren.
Voer nooit weerstandsmetingen uit op schakelingen die onder stroom staan.
Never perform resistance measurements on live circuits.
ALGEMEN E OMS C H RIJVING
Deze module is een batterijgestuurde, handbediende 3 ½-digit digitale multimeter. Met dit apparaat kunt u
weerstanden, gelijk- en wisselspanning en gelijkstroom meten. U kunt continuïteitstesten uitvoeren en u kunt er
zelfs dioden en transistors mee testen.

BESCHRIJVING VAN HET INSTRUMENTENBORD :
1. Scherm met achtergrondverlichting (de achtergrondverlichting brandt alleen als het hele toestel
ingeschakeld is met de schakelaar op de achterkant) 3 ½ digits, 7 segmenten, LCD: 15mm hoog.
2 Draaiknop
Wordt gebruikt om de gewenste functie en het bereik in te stellen. Doet ook dienst als voedingsschakelaar (ON/OFF).
3 Hold - toets
Wanneer u deze knop indrukt, zal het uitleesvenster de laatste waarde vasthouden. Het " " -symbool
blijft op de LCD tot u de knop opnieuw indrukt.
4 "10A" jack
Wanneer u het rode testsnoer aansluit op deze connector, kunt u een max. stroom meten van 10A..
5 "COM" jack
Sluit het zwarte (negatieve) testsnoer aan.
6 "VΩmA" jack
Sluit het rode (positieve) testsnoer aan op deze connector. U kunt nu spanning, weerstand en stroom meten
(uitgez. 10A).
