10.1 GELIJKSPANNING METEN
1. Stel het gewenste meetbereik in d.m.v. de draaiknop. Stel de
schakelaar in op het grootste bereik indien de te meten gelijkspanning
niet vooraf gekend is en verminder dan geleidelijk om de ideale
resolutie te bepalen.
2. Sluit de meetsnoeren aan op de meetbron.
3. U kunt nu de intensiteit van de spanning en de polariteit van het rode
meetsnoer aflezen op de LCD-display.
10.2 WISSELSPANNING METEN
1. Stel het gewenste meetbereik in d.m.v. de draaiknop.
2. Sluit de meetsnoeren aan op de meetbron.
3. U kunt nu de intensiteit van de spanning aflezen op de LCD-display.
11. Stroom meten
Meet niet in circuits met spanningen > 500 V
Wees uiterst voorzichtig bij metingen hoger dan 60 DC of 30 VAC
rms.
Houd tijdens metingen uw vingers steeds achter de
beschermingsrand van de meetpennen!
1. Stel het gewenste meetbereik in d.m.v. de draaiknop (DCA).
2. Sluit de meetsnoeren IN SERIE aan op het circuit waarvan u de
belasting wilt meten.
3. U kunt nu de intensiteit van de spanning en de polariteit van het rode
meetsnoer aflezen op de LCD-display.
12. Weerstand meten
Voer geen weerstandsmetingen uit in circuits waarop spanning
aanwezig is. Zorg ervoor condensatoren in het circuit volledig
ontladen zijn.
1. Plaats de draaiknop in de gewenste stand ("").
2. Sluit de meetsnoeren aan op de weerstand en lees de LCD-display.
3. Zorg ervoor dat bij weerstandsmetingen geen spanning meer op het
circuit staat en condensatoren volledig ontladen zijn.
