4. Opsætning
4.1 Batteriinstallation
The Fluke 301D/ESP requires two AAA batteries. These are typically included. To install or replace batteries:
- Ensure the meter is turned OFF.
- Find batterirummet på bagsiden af måleren.
- Brug en skruetrækker til at åbne batteridækslet.
- Insert the two AAA batteries, observing correct polarity (+/-).
- Sæt batterirummets dæksel på igen og fastgør det med skruen.
4.2 Tilslutning af testledninger
For bdtage, resistance, continuity, capacitance, and diode measurements, connect the TL75-4201 test leads:
- Insert the black test lead into the "COM" (common) input jack.
- Insert the red test lead into the "VΩ" (voltage/resistance) input jack.
5. Betjeningsvejledning
The Fluke 301D/ESP offers multiple measurement functions, selected via the rotary dial.
5.1 AC/DC strømmåling (Clamp)
To measure AC or DC current up to 600A:
- Drej drejeknappen til A~ (AC Current) or A= (DC Current) position.
- Press the jaw release lever to open the clamp kæbe.
- Enclose a single conductor with the clamp kæbe. Sørg for, at kæben er helt lukket.
- Read the current value on the display. For DC current, observe the polarity.
- For DC current measurements, press the NUL button to clear any offset before taking a reading.

5.2 bindtage-måling (AC/DC)
Til at måle AC eller DC voltage:
- Connect the test leads as described in Section 4.2.
- Drej drejeknappen til V~ (AC Voltage) eller V= (DC bindtage) stilling.
- Touch the test probes to the points where voltage skal måles.
- Læs bindtage -værdi på displayet.
5.3 Modstandsmåling
Sådan måles modstand:
- Sørg for, at kredsløbet er spændingsløst, før du måler modstanden.
- Connect the test leads as described in Section 4.2.
- Drej drejeknappen til Ω (Resistance) position.
- Touch the test probes across the component or circuit to be measured.
- Læs modstandsværdien på displayet.
5.4 Kontinuitetstest
To perform a continuity test:
- Sørg for, at kredsløbet er spændingsløst.
- Connect the test leads as described in Section 4.2.
- Drej drejeknappen til Ω (Resistance) position and press the VÆLGE button until the continuity symbol ()))) vises.
- Touch the test probes across the circuit or component.
- A continuous beep indicates a complete circuit (continuity).
5.5 Kapacitansmåling
Sådan måles kapacitans:
- Ensure the capacitor is discharged before measurement.
- Connect the test leads as described in Section 4.2.
- Drej drejeknappen til KASKET (Capacitance) position.
- Touch the test probes across the capacitor terminals.
- Læs kapacitansværdien på displayet.
5.6 Diodetest
To perform a diode test:
- Sørg for, at kredsløbet er spændingsløst.
- Connect the test leads as described in Section 4.2.
- Drej drejeknappen til Ω (Resistance) position and press the VÆLGE button until the diode symbol (->|) vises.
- Touch the red probe to the anode and the black probe to the cathode of the diode.
- Læs videre bindtage drop on the display. Reverse the probes; the display should show "OL" (open loop) for a good diode.
5.7 Frequency Measurement (Voltage og nuværende)
Sådan måles frekvensen:
- For bdtage frequency, connect test leads and set the dial to V~. Trykke Hz knap.
- For current frequency, clamp the meter around a conductor and set the dial to A~. Trykke Hz knap.
- Read the frequency value in Hertz (Hz) on the display.

7. Fejlfinding
If your Fluke 301D/ESP is not functioning as expected, consider the following common issues:
- Intet display/svagt display: Kontrollér batteriniveauet, og udskift det om nødvendigt. Sørg for, at batterierne er isat med den korrekte polaritet.
- Upræcise læsninger:
- Ensure test leads are fully inserted and not damaged.
- For current measurements, ensure only a single conductor is within the clamp kæbe.
- For DC current, perform a ZERO adjustment before measurement.
- Verify the correct function is selected on the rotary dial.
- "OL" (Overload) Display: The measured value exceeds the meter's range for the selected function. Select a higher range if available, or ensure the measurement is within the meter's specifications.
If problems persist, contact Fluke customer support for assistance.
