Veiligheidsinligting

Om veilige werking en diens van die meter te verseker, volg hierdie instruksies:

• Read and understand all instructions and safety information in this manual before operating the meter.
• Moenie die maksimum invoerwaardes wat vir elke meetbereik gespesifiseer is, oorskry nie.
• Wees versigtig wanneer u met voltagbo 30V AC RMS, 42V piek, of 60V DC. Hierdie volumestagdit hou 'n skokgevaar in.
• Ontkoppel altyd die toetsdrade van die stroombaan voordat u funksies of reekse verander.
• Inspekteer toetsdrade vir beskadigde isolasie of blootgestelde metaal. Vervang indien beskadig.
• Moenie die meter gebruik as dit beskadig lyk of as die kas oop is nie.
• Maak seker dat die batteryklep stewig toe is voor gebruik.
• Do not use the meter in wet environments or in the presence of explosive gas or dust.
• Wanneer stroom gemeet word, maak seker dat die meter in serie met die las gekoppel is en dat die stroombaan gedeaktiveer is voordat u dit koppel.

Opstelling

Battery installasie

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

1. Maak seker dat die multimeter afgeskakel is en ontkoppel alle toetsdrade.
2. Vind die batteryklepdeksel aan die agterkant van die toestel.
3. Gebruik 'n skroewedraaier om die batterykompartement oop te maak.
4. Insert two 1.5V AAA batteries, observing the correct polarity (+ and -).
5. Plaas die deksel van die batterykompartement terug en maak dit met die skroef vas.

Toetsleidings verbind

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:

• Vir Voltage, Resistance, Capacitance, and Continuity: Connect the red lead to the VΩ-4- terminaal.
• For Current (up to 10A): Connect the red lead to the 10A UNFUSED terminaal.

Bedryfsinstruksies

Powering On/Off and Automatic Identification

Prentbeskrywing: 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. Om die toestel aan te skakel, 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.

Kontakloos Voltage (NCV) Toets

Prentbeskrywing: 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 toets:

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. Die multimeter sal die teenwoordigheid van WS-volume aanduitage deur 'n hoorbare piep en/of visuele aanwyser.

Data Hold en Backlight

Druk die 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.

General Measurement Principles

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

• Voltage Meting (WS/GS): Connect leads in parallel with the circuit.
• Stroommeting (WS/GS): Connect leads in series with the circuit. Ensure the circuit is de-energized before connecting.
• Weerstandmeting: Ensure the circuit is de-energized before measuring resistance. Connect leads across the component.
• Kapasitansiemeting: Ensure the capacitor is discharged before measuring.
• Frekwensiemeting: Connect leads to the signal source.
• Kontinuïteitstoets: For checking circuit continuity. An audible beep indicates continuity.

Prentbeskrywing: This image displays the multimeter and lists its key measurement capabilities: 1KHz True RMS, NCV induced voltage, AC and DC current, AC and DC voltage, Zero fire line identification, and Resistance on and off. It also shows icons for various measurement types like voltage, current, frequency, and diode test, indicating the multimeter's versatility.
