1. Impostazione
1.1 Collegamento dell'alimentazione
The CL24R requires a DC12V 1A power supply or a PD12V PD voltage trigger power supply. Ensure you use the correct power adapter for your region. A US to EU adapter is included if applicable. If your country cannot use the provided power supply, it is recommended to source a local DC12V 1A power supply.
1.2 Metodi di cablaggio
The device supports two wiring methods for connecting the battery or power source:
- Metodo di cablaggio a due fili: This is a simpler method. Connect the positive and negative terminals of the battery to the A+ and A- terminals of the tester respectively.
- Metodo di cablaggio a quattro fili: Recommended for more accurate voltage measurements, as it compensates for voltage drop across the wires. Connect the positive and negative terminals of the battery to A+ and A- for current, and V+ and V- for voltage rilevamento.
