General Measurement Principles

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

• ສະບັບtage ການ​ວັດ​ແທກ (AC/DC): Connect leads in parallel with the circuit.
• ການວັດແທກກະແສໄຟຟ້າ (AC/DC): Connect leads in series with the circuit. Ensure the circuit is de-energized before connecting.
• ການວັດແທກຄວາມຕ້ານທານ: Ensure the circuit is de-energized before measuring resistance. Connect leads across the component.
• ການວັດແທກຄວາມອາດສາມາດ: Ensure the capacitor is discharged before measuring.
• ການວັດແທກຄວາມຖີ່: Connect leads to the signal source.
• ການທົດສອບຄວາມຕໍ່ເນື່ອງ: For checking circuit continuity. An audible beep indicates continuity.

ລາຍລະອຽດຮູບພາບ: 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.
