Spezzjoni Inizjali:
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.
Istruzzjonijiet Operattivi
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. Kejl tal-Volum DCtage (DCV):
- Set the function/range selector dial to the desired DCV range (e.g., 0.25V, 2.5V, 10V, 50V, 250V, 1000V).
- Qabbad il-wajer tat-test aħmar man-naħa pożittiva (+) taċ-ċirkwit u l-wajer tat-test iswed man-naħa negattiva (-).
- Aqra l-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. Kejl AC Voltage (ACV):
- Set the function/range selector dial to the desired ACV range (e.g., 10V, 50V, 250V, 1000V).
- Qabbad il-wajers tat-test mal-vultaġġ ACtagsors e.
- Aqra l-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):
- TWISSIJA: Qatt ma tqabbad il-multimetru b'mod parallel ma' voltagSors elettroniku meta tkejjel il-kurrent. Dejjem qabbad f'serje mat-tagħbija.
- 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):
- TWISSIJA: Kun żgur li ċ-ċirkwit ma jkollux l-enerġija u li l-kapaċitaturi kollha jkunu skarikati qabel ma tkejjel ir-reżistenza.
- 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.
- Connect the test leads across the component whose resistance you wish to measure.
- 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):
- TWISSIJA: Ensure the capacitor is fully discharged before connecting the multimeter.
- Set the function/range selector dial to the 'C' (Capacitance) range.
- Qabbad il-wajers tat-test mal-kapaċitatur.
- 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.
- Connect the red test lead to the anode and the black test lead to the cathode of the diode. The meter should show a low resistance reading (forward bias).
- Reverse the test leads. The meter should show a very high or infinite resistance reading (reverse bias).
- This function can also be used to check LEDs.
