Informazzjoni dwar is-Sigurtà

Biex tiżgura t-tħaddim u s-servizz sikuri tal-miter, segwi dawn l-istruzzjonijiet:

• Read and understand all instructions and safety information in this manual before operating the meter.
• Teċċedix il-valuri massimi tad-dħul speċifikati għal kull medda ta' kejl.
• Oqgħod attent meta taħdem bil-voltag'il fuq minn 30V AC RMS, 42V peak, jew 60V DC. Dawn il-volumitages joħolqu periklu ta' xokk.
• Dejjem skonnettja l-wajers tat-test miċ-ċirkwit qabel ma tbiddel il-funzjonijiet jew il-firxiet.
• Spezzjona l-wajers tat-test għal insulazzjoni bil-ħsara jew metall espost. Ibdel jekk bil-ħsara.
• Tħaddimx il-miter jekk jidher li għandu l-ħsara jew jekk il-kaxxa tkun miftuħa.
• Kun żgur li l-għatu tal-batterija jkun magħluq sew qabel l-operazzjoni.
• Do not use the meter in wet environments or in the presence of explosive gas or dust.
• When measuring current, ensure the meter is connected in series with the load and the circuit is de-energized before connecting.

Setup

Installazzjoni tal-batterija

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

1. Kun żgur li l-multimetru jkun mitfi u skonnettja l-wajers tat-test kollha.
2. Sib l-għatu tal-kompartiment tal-batterija fuq wara tal-apparat.
3. Uża tornavit biex tiftaħ il-kompartiment tal-batterija.
4. Daħħal żewġ batteriji AAA ta' 1.5V, waqt li tosserva l-polarità korretta (+ u -).
5. Ibdel l-għatu tal-kompartiment tal-batterija u waħħalha bil-kamin.

Konnessjoni taċ-Ċombijiet tat-Test

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:

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

Istruzzjonijiet Operattivi

Powering On/Off and Automatic Identification

Deskrizzjoni tal-Immaġni: 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. Biex tixgħel l-apparat, 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.

Mhux Kuntatt VoltagTest tal-e (NCV)

Deskrizzjoni tal-Immaġni: 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. The multimeter will indicate the presence of AC voltage through an audible beep and/or visual indicator.

Żomm tad-Data u Backlight

Agħfas il- 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.

• VoltagKejl (AC/DC): Connect leads in parallel with the circuit.
• Current Measurement (AC/DC): Connect leads in series with the circuit. Ensure the circuit is de-energized before connecting.
• Kejl tar-Reżistenza: Ensure the circuit is de-energized before measuring resistance. Connect leads across the component.
• Kejl tal-Kapaċitanza: Ensure the capacitor is discharged before measuring.
• Kejl tal-Frekwenza: Connect leads to the signal source.
• Test ta' Kontinwità: For checking circuit continuity. An audible beep indicates continuity.

Deskrizzjoni tal-Immaġni: 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.
