5. Istruzzjonijiet Operattivi
5.1 Proċedura Ġenerali tal-Kejl
- Dawwar id-dial rotatorju għall-funzjoni tal-kejl mixtieqa.
- Qabbad il-wajers tat-test jew il-klamp the jaws to the circuit under test as appropriate for the selected function.
- Read the measurement value(s) on the dual LCD display.
- If the reading is unstable or out of range, adjust the function or range if manual ranging is available.
5.2 Kejl tal-Kurrent AC/DC (Clamp)
This function measures current without breaking the circuit.
- Dawwar l-arloġġ li jdur lejn il- A~ (Kurrent AC) jew A- Pożizzjoni (Kurrent DC).
- Iftaħ il-clamp xedaq billi tagħfas il-grillu.
- Enclose only one conductor of the circuit within the jaws. Ensure the jaws are fully closed.
- Aqra l-valur tal-kurrent fuq id-displej. Għal kurrent DC, osserva l-polarità.
