Wire Definitions
XH-2.54-3P Fine Wires (Total length: 155mm)
- Fine Red Wire: Positive terminal of operating power supply. Must NOT connect to sources exceeding 30V.
- Fine Black Wire: Negative terminal of operating power supply. Shares ground with thick black wire. Not required when using a shared power supply.
- Thin Yellow Wire: Voltage test lead — connects to the positive terminal of the test circuit power supply.
VH-3.96-2P Thick Wires (Total length: 165mm) — Current Test Leads
- Thick Red Wire: Current test positive terminal. Connects in series after the negative terminal of the load. Connect this wire last and disconnect first.
- Thick Black Wire: Current test negative terminal. Connects to the power supply negative terminal. Connect first and disconnect last.
⚠️ Important: Thick wires must be connected in parallel with shunt resistors. Do not connect them directly to power supply terminals — this will cause a short circuit.

Frequently Asked Questions
Q: What is the operating voltage range for the DC730 digital power meter?
A: The DC730 meter operates on a supply voltage of DC 7–30V, connected via the XH-3P red and black leads. It is critical that you do not exceed 30V on the operating supply, as this may damage the unit.
Q: Can I fine-tune the voltage and current readings on the DC730?
A: Yes. The DC730 supports fine adjustment of both voltage and current display values through on-board adjustable resistors. This allows you to calibrate the meter's readings for greater accuracy in your specific application.
Q: How do I safely connect the thick red and black current test wires?
A: The thick wires must always be connected in parallel with the on-board shunt resistor — never directly to power supply terminals, as this will cause a short circuit. When connecting, attach the thick black wire first and disconnect it last; attach the thick red wire last and disconnect it first.
Q: Is the DC730 power meter suitable for panel mounting?
A: Yes. The DC730 has a compact footprint (79.3 × 42.1 × 26.2 mm) with a mounting aperture of 71.7 × 39.1 mm, making it ideal for installation into enclosures, DIY project panels, or custom lab bench setups.
