2. Opsætning
2.1. Batteriinstallation
The Fluke 1653B is battery-powered. Before initial use, or when the low battery indicator appears, ensure fresh batteries are installed. Refer to the battery compartment cover for correct polarity and battery type (typically AA or C cells, depending on the model variant).
- Find batterirummet på bagsiden af enheden.
- Open the battery compartment cover using a screwdriver or coin if necessary.
- Insert the required number of batteries, observing the correct polarity (+/-) as indicated inside the compartment.
- Luk dækslet til batterirummet forsvarligt.
2.2. Første opstart
Press the green power button (labeled with a circle and vertical line) located near the bottom left of the control panel to turn on the device. The digital display will illuminate and perform a self-test.
3. Betjeningsvejledning
This section provides general guidance for operating the Fluke 1653B. Always refer to the on-screen prompts and safety warnings during operation.
3.1. Selecting a Measurement Function
Use the large rotary dial on the right side of the device to select the desired measurement function. The selected function will be indicated on the display.
- VOLTS (V.): For measuring AC/DC voltage.
- INSULATION (RISO): For insulation resistance tests.
- CONTINUITY (RLO): For low-ohm continuity tests.
- LOOP (ZL NO TRIP): For loop impedance measurement without tripping RCDs.
- LOOP (ZL HI CURRENT): For high current loop impedance measurement.
- ΔT RCD TIME: For RCD trip time measurement.
- IΔN RCD TRIP: For RCD trip current measurement.
- RE JORD: For earth resistance measurement.
- FASEROTATION: For determining phase sequence.
3.2. Udførelse af en test
Once a function is selected and test leads are connected appropriately, press the large PRØVE button (located on the bottom left) to initiate the measurement. The display will show the measurement result.
De NUL button can be used to null out lead resistance for accurate low-ohm measurements.
3.3. Using Memory Functions
The device includes internal memory for storing measurement values. Use the HUKOMMELSE button and the arrow keys to navigate and save readings. Refer to the on-screen prompts for specific memory operations.
- Trykke HUKOMMELSE to access memory functions.
- Use the up/down arrow keys to scroll through stored readings or memory locations.
- Function buttons (F1-F4) may provide additional options related to memory, such as saving, recalling, or deleting data.
3.4. PC Interface
The Fluke 1653B features a PC interface for documentation and reporting. Connect the device to a computer using the appropriate cable (sold separately) and use Fluke's software (if applicable) to download and analyze stored data.
4. Vedligeholdelse
Proper maintenance ensures the longevity and accuracy of your Fluke 1653B.
4.1. Rensning
Clean the instrument casing med annonceamp cloth and mild detergent. Do not use abrasive cleaners or solvents. Ensure the device is powered off and disconnected from any electrical circuits before cleaning.
4.2. Opbevaring
When not in use for extended periods, remove the batteries to prevent leakage. Store the device in a dry, cool place, away from direct sunlight and extreme temperatures.
4.3. Kalibrering
