Inspecția inițială:

Before first use, inspect the multimeter for any signs of physical damage. Ensure the test leads are securely attached and free from cuts or abrasions.

Instrucțiuni de operare

Before taking any measurement, ensure the multimeter is set to the correct function and range. Always start with a higher range if the approximate value is unknown to prevent damage to the meter.

1. Măsurarea tensiunii continue (DC Vol)tage (DCV):

• Set the function/range selector dial to the desired DCV range (e.g., 0.25V, 2.5V, 10V, 50V, 250V, 1000V).
• Conectați sonda roșie de testare la partea pozitivă (+) a circuitului și sonda neagră la partea negativă (-).
• Citiți voltage value on the DCV scale of the analog display.

Note: The DCV ranges include 0 - 0.1V ±1% and 0.25V/2.5/10V/50V/250/1000V ±3%.

2. Măsurarea AC Voltage (ACV):

• Set the function/range selector dial to the desired ACV range (e.g., 10V, 50V, 250V, 1000V).
• Conectați sondele de testare la priza de curent alternativtage sursa.
• Citiți voltage value on the ACV scale of the analog display.

Note: The ACV ranges are 0 - 10/50/250/1000V ±4%.

3. Measuring DC Current (DCA):

• AVERTIZARE: Nu conectați niciodată multimetrul în paralel cu un vol...tagsursă de curent atunci când măsurați curentul. Conectați întotdeauna în serie cu sarcina.
• Set the function/range selector dial to the desired DCA range (e.g., 50µA, 2.5mA, 25mA, 250mA).
• Break the circuit and connect the multimeter in series with the load. The red lead connects to the higher potential side, and the black lead to the lower potential side.
• Read the current value on the DCA scale.

Note: The DCA ranges are 0 - 50µA/2.5mA/25mA/250mA ±3%. This meter can measure currents as low as 10 micro amps.

4. Measuring Resistance (Ω):

• AVERTIZARE: Asigurați-vă că circuitul este dezactivat și că toți condensatorii sunt descărcați înainte de a măsura rezistența.
• Set the function/range selector dial to the desired Resistance range (e.g., x1, x10, x100, x1K, x10K, x100K).
• Short the test leads together (touch red to black).
• Adjust the Ω-ADJ knob until the needle points to '0' on the Ohms scale. This zeros the ohmmeter.
• Conectați sondele de testare la componenta a cărei rezistență doriți să o măsurați.
• Read the value on the Ohms scale and multiply by the selected range multiplier.

Note: The Resistance ranges are 0 - 2K/20K/2MKohm ±3% and 200M ±5%.

5. Capacitance Estimation (C):

• AVERTIZARE: Ensure the capacitor is fully discharged before connecting the multimeter.
• Set the function/range selector dial to the 'C' (Capacitance) range.
• Conectați sondele de testare la condensator.
• Observe the needle's deflection. The scale provides an estimation of capacitance.

Note: The Capacitance range is 0 - 10 µF.

6. Diode Check:

• Set the function/range selector dial to the Diode check position.
• Conectați sonda roșie la anod și sonda neagră la catodul diodei. Aparatul de măsură ar trebui să afișeze o rezistență scăzută (polarizare directă).
• Inversați sondele de testare. Aparatul de măsură ar trebui să afișeze o rezistență foarte mare sau infinită (polarizare inversă).
• This function can also be used to check LEDs.

Întreţinere

curatenie:

Ștergeți carcasa cu reclamăamp cloth and mild detergent. Do not use abrasives or solvents. Keep the display clean for optimal readability.

Înlocuire baterie:

Replace batteries when the meter's readings become erratic or the needle does not zero correctly in resistance mode. Refer to the "Setup" section for battery installation instructions.
