Oppsett

Installasjon av batteri

The BST-58F multimeter requires 2 x 1.5V AAA batteries for operation. To install or replace batteries:

1. Sørg for at multimeteret er slått av og koble fra alle testledninger.
2. Finn batteridekselet på baksiden av enheten.
3. Bruk en skrutrekker for å åpne batterirommet.
4. Sett inn to 1.5 V AAA-batterier, og pass på riktig polaritet (+ og -).
5. Sett på plass batteridekselet og fest det med skruen.

Koble til testledninger

Always connect the black test lead to the COM terminal. Connect the red test lead to the appropriate input terminal based on the measurement type:

• For Voltage, Resistance, Capacitance, and Continuity: Connect the red lead to the VΩ-4- terminal.
• For strøm (opptil 10A): Koble den røde ledningen til 10A UNFUSED terminal.

Bruksanvisning

Powering On/Off and Automatic Identification

Bildebeskrivelse: This image illustrates the power-on process and automatic measurement function. The left panel shows the multimeter off, with text "1: Long press the yellow button to start the device". The right panel shows the multimeter with test leads connected, indicating "2: Automatic measurement of gear position". The screen displays "APO" and "HOLD" indicators.

1. For å slå på enheten, long press the yellow O/H button. The multimeter will automatically identify the measurement type (voltage, resistance, continuity) within 3 seconds when test leads are connected to a circuit.
2. The multimeter features an automatic power-off function to save battery.

Non-Contact Voltage (NCV)-test

Bildebeskrivelse: This image shows the multimeter's NCV (Non-Contact Voltage) test feature. The text "NCV Non-contact Test" is prominent, with an arrow pointing to the NCV sensing area at the top of the device. The screen shows "APO" and the NCV/B button is visible.

To perform a Non-Contact Voltage test:

1. Long press the NCV/B button to enter induction mode.
2. Move the NCV sensing area (located at the top of the multimeter) close to the conductor being tested.
3. Multimeteret vil indikere tilstedeværelsen av AC-volumtage gjennom et hørbart pip og/eller en visuell indikator.

Datahold og bakgrunnsbelysning

Trykk på H/* button briefly to activate the Data Hold function, which freezes the current reading on the display. Press it again to release. Long press the H/* button to turn the screen backlight on or off for improved visibility in dark environments.

Generelle måleprinsipper

The BST-58F automatically identifies the measurement type. Ensure test leads are correctly connected for the desired measurement.

• Voltage-måling (AC/DC): Connect leads in parallel with the circuit.
• Strømmåling (AC/DC): Connect leads in series with the circuit. Ensure the circuit is de-energized before connecting.
• Motstandsmåling: Ensure the circuit is de-energized before measuring resistance. Connect leads across the component.
• Kapasitansmåling: Ensure the capacitor is discharged before measuring.
• Frekvensmåling: Koble ledningene til signalkilden.
• Kontinuitetstest: For checking circuit continuity. An audible beep indicates continuity.
