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 temperature 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 common 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 solvents and make sure no liquid penetrates the housing of the device.

MULTIMETER
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 veiligheidsen 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 voltageen 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 schuurof 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.
ALGEMENE OMSCHRIJVING
Deze module is een batterijgestuurde, handbediende 3 ½-digit digitale multimeter. Met dit apparaat kunt u weerstanden, gelijken wisselspanning en gelijkstroom meten. U kunt continuïteitstesten uitvoeren en u kunt er zelfs dioden en transistors mee testen.
