Wire Connection:

• Thin Red line (VCC): Power Supply + (DC 3.5-30V +)
• (if the measure voltage between DC 3.5-30V, then the Thin Yellow line and Thin Red line can connect together)
• Thin Black line (GND): Power Supply – (DC 3.5-30V -), Measure Voltage – (DC 0-100V -)
• Thin Yellow line (VIN): Measure Voltage + (DC 0-100V +)
• Thick Red line (I+): Current Input +
• Thick Black line (I-): Current Input –
• More detail please check the description picture.

Error Phenomena:

• Due to the aging of the device and change of ambient temperature1. The error becomes larger when measuring small current.Solution: When there is no load, short-circuit 2 pads of KEY and then power on, the module will automatically do zero calibration, after that shut off the module and cut the short circuit point.
• 2. The error becomes larger in whole measurement range
  Solution: When connecting load(half of the range is best), keep adjusting R7 until it displays the same value with the more advanced calibration source.

Package Included:

• 1 x DC 100V 10A Digital Voltmeter & Ammeter
