5. Opsætning

5.1 Batteriinstallation

1. Find batteridækslet på bagsiden af ​​måleren.
2. Use a screwdriver to loosen the screw(s) and remove the cover.
3. Insert the two LR44 batteries, observing the correct polarity (+/-) as indicated inside the compartment.
4. Replace the battery cover and secure it with the screw(s).

5.2 Tilslutning af testledninger

Insert the banana plugs of the test leads into the appropriate input jacks on the meter. For most measurements, the common (COM) jack will be used with the black lead, and the V1, V2, V3, or A jacks will be used with the colored leads (red, yellow, green) depending on the measurement type and phase configuration.

5.3 USB/RS232 Interface Setup

To connect the meter to a computer for data logging and analysis:

1. Install the provided PC data record graph software from the CD-ROM onto your Windows OS computer.
2. Connect one end of the RS232 interface cable to the meter's RS232 port.
3. Connect the other end of the cable to an available USB port on your computer (an RS232-to-USB adapter may be required if your computer lacks an RS232 port).
4. Follow the software instructions to establish communication with the meter.

6.1 Tænd/sluk

To power on the meter, rotate the function switch from the 'OFF' position to any desired measurement function. To power off, rotate the switch back to 'OFF'.

6.2 Funktionsvalg

The rotary switch allows selection of different measurement modes. Ensure the switch is set to the appropriate function before taking a measurement.

6.3 Måleprocedurer

AC-strømmåling:

1. Rotate the function switch to the 'A' (AC Current) position.
2. Åbn clamp kæberne ved at trykke på aftrækkeren.
3. Enclose only one conductor of the circuit within the jaws. Ensure the jaws are fully closed.
4. Aflæs den aktuelle værdi på displayet.

AC Voltage Measurement (3-Phase):

1. Rotate the function switch to the 'V' (AC Voltage) stilling.
2. Connect the test leads to the V1, V2, V3, and COM input jacks.
3. Connect the test leads to the respective phase conductors and neutral/ground of the 3-phase system.
4. The meter will display the voltage readings for each phase.

Power Measurement (Active, Apparent, Reactive, Power Factor):

1. Rotate the function switch to the 'W/PF' (Power/Power Factor) position.
2. Connect the test leads and clamp the current jaws as required for 3-phase power measurement.
3. The meter will display active power (W), apparent power (VA), reactive power (VAR), and power factor (PF).

6.4 Specialfunktioner

• Data Hold: Tryk på 'HOLD'-knappen for at fryse den aktuelle aflæsning på displayet. Tryk igen for at slippe.
• MAX/MIN Measurement: Press the 'MAX/MIN' button to record the maximum and minimum values during a measurement session. Press again to cycle through MAX, MIN, and current readings.
