1. Introduktion
The VOLTCRAFT VC-750 E is a versatile digital clamp meter designed for non-contact AC/DC current measurement and comprehensive multimeter functions. This device allows for current measurements without interrupting the circuit, making it ideal for electricians, technicians, and service personnel. Its robust, splash-proof (IP54) design ensures reliable operation in demanding environments.
2. Sikkerhedsoplysninger
Always adhere to safety precautions when operating electrical measuring devices. Failure to do so may result in injury or damage to the device. This device is rated CAT IV 600 V, indicating its suitability for measurements at the source of the low-voltage-installation, såsom elmålere og primære overstrømsbeskyttelsesanordninger.
- Sørg for, at enheden er i god stand før brug.
- Overskrid ikke de maksimale inputværdier for nogen funktion.
- Use only the provided test leads or equivalent safety-rated accessories.
- Undgå kontakt med strømførende kredsløb.
- Do not operate the device in wet conditions or explosive atmospheres. The IP54 rating protects against dust and splashing water, but not immersion.
- Udskift batterierne, når indikatoren for lavt batteri vises.

5. Opsætning
5.1 Batteriinstallation
- Find batterirummet på bagsiden af enheden.
- Brug en skruetrækker til at åbne batteridækslet.
- Insert three (3) AAA batteries, observing the correct polarity (+/-).
- Sæt batteridækslet på igen og fastgør det med skruen.
5.2 Tilslutning af testledninger
For bdtage, resistance, capacitance, and diode measurements, connect the test leads:
- Indsæt sort testledning ind i KOM (fælles) indgangsstik.
- Indsæt rød testledning ind i VΩCAP indgangsstik.
6. Betjeningsvejledning
6.1 Tænd/sluk
Turn the rotary switch from the OFF position to the desired measurement function to power on the device. Turn it back to OFF to power off.
6.2 AC/DC strømmåling (Clamp Fungere)
This function allows non-contact current measurement.
- Set the rotary switch to the “A” (Ampere) range for AC or DC current.
- Tryk på clamp udløser for at åbne cl'enamp kæbe.
- Omslut en enkelt leder med clamp kæbe. Sørg for, at kæben er helt lukket.
- Aflæs den aktuelle værdi på displayet.
6.3 bindtage-måling (AC/DC)
- Tilslut testledningerne som beskrevet i afsnit 5.2.
- Set the rotary switch to the “V” (Voltage) range for AC or DC voltage.
- Tilslut testproberne parallelt til det kredsløb eller den komponent, der skal måles.
- Læs bindtage -værdi på displayet.
6.4 Modstandsmåling
- Tilslut testledningerne som beskrevet i afsnit 5.2.
- Set the rotary switch to the “Ω” (Ohm) range.
- Sørg for, at kredsløbet eller komponenten er spændingsløs, før du måler modstanden.
- Tilslut testproberne på tværs af komponenten.
- Læs modstandsværdien på displayet.
6.5 Kapacitansmåling
- Tilslut testledningerne som beskrevet i afsnit 5.2.
- Set the rotary switch to the “CAP” (Capacitance) range.
- Sørg for, at kondensatoren er helt afladet før måling.
- Tilslut testproberne på tværs af kondensatoren.
- Læs kapacitansværdien på displayet.
6.6 Diodetest og kontinuitet
- Tilslut testledningerne som beskrevet i afsnit 5.2.
- Set the rotary switch to the “Ω” (Ohm) range and use the function button to select Diode Test or Continuity.
- For diode test, connect the probes across the diode. The forward voltage drop vil blive vist.
- For continuity, connect the probes across the circuit. An audible tone indicates continuity.
6.7 Specialfunktioner
- TrueRMS Measurement: The VC-750 E provides TrueRMS measurements for accurate readings of non-sinusoidal AC waveforms.
