•Data hold
Druk op HOLD om de aflezing op het scherm vast te spijkeren. Druk opnieuw om de meting te hervatten.
•Automatische uitschakeling
De meter wordt na 15 minuten inactiviteit automatisch uitgeschakeld. Druk op WAKE of draai aan de draaischakelaar om de multimeter opnieuw in
te schakelen. Schakel de automatische uitschakeling uit door de voedingsschakelaar en WAKE gelijktijdig in te drukken. Schakel de meter na
gebruik uit via de voedingsschakelaar aangezien een multimeter in stand-by toch verbruikt.
•Relatieve metingen
Deze functie kan gebruikt worden voor alle meetfuncties uitgenomen voor frequentiemeting, diodemeting en meting van cyclische verhouding. Druk
op REL∆om de relatieve waarde vast te leggen. De weergegeven waarde stelt nu de huidige gemeten waarde min de vastgelegde relatieve waarde.
Druk opnieuw om de functie te verlaten.
•Maximum-/minimumwaarde
Deze functie kan gebruikt worden voor alle meetfuncties uitgenomen voor frequentie- en diodemeting. Druk op MAX/MIN om de maximum-, de
minimum- of beide waarden te bepalen. Houd MAX/MIN gedurende 2 seconden ingedrukt om de functie te verlaten.
•De multimeter aan een computer koppelen
Koppel uw DVM2000 aan een pc met behulp van de meegeleverde optische usb-kabel. Houd HOLD gedurende 2 seconden ingedrukt om de
gegevens naar de computer door te zenden. Met de juiste software kunt u nu de gegevens editen. Houd HOLD gedurende 2 seconden ingedrukt om
