5. Setup
5.1 Power Supply Methods
The TS457 offers two primary methods for power supply:
-
DC 5V Two-Wire Power Supply:
- Connect the thin red wire to the positive electrode of your DC 5V power source.
- Connect the thin black wire to the negative pole of your DC 5V power source.
- The yellow wire indicates charging status and should NOT be connected normally during operation. Ensure proper insulation for this wire if not in use.
-
18650 Battery + Power Adapter Board:
- Utilize an 18650 battery in conjunction with a compatible power adapter board (purchased separately) for portable operation.
5.2 Connecting for Measurement (Kelvin Clamp Method)
For accurate measurements, especially of internal resistance, the AC 4-wire (Kelvin) method is recommended. You will need an XH2.54-4P signal acquisition cable and Kelvin clamps (accessories may need to be purchased separately).
- Prepare a 5V power supply or an 18650 battery for the meter.
- Connect the XH2.54-4P signal acquisition cable to the back of the meter.
- Attach Kelvin clamps to the ends of the signal acquisition cable.
- Connect the Kelvin clamps to the positive and negative terminals of the battery or component you wish to test. Ensure good contact.
