• Dimensions: 48 * 29 * 21 mm
• Cutting size:45mm*26 mm
• Power Supply: 3.5-28V DC 12V
• Temperature range: -55 °c - 110 °c (resolution 0.1 °c)
• Power meter range: DC 0.0-99.9W (resolution 0.1W)
• Voltage range: DC 0.00-33.00V (resolution 0.01V)
• Current meter range: automatic precision variable DC 0-999.9mA-3.000A
• Accuracy: ± (0.3% +2 digits)
• Refresh rate: about 200ms / times
• Display: 0.28-inch 4 digit dual LED digital tube
• Display Color: Red+Green

• Voltage Current Meter Mode: The default mode voltage current meter.
• Thermometer power meter mode: press the switch again to switch to the thermometer power meter mode
• Top of the display is the measured voltage, below is the measured current. When measuring current, the power from the measuring circuit.
• Top of the display is the measured temperature, displays *** C; below is the measured power, displays *** P. Without 18B20 chip, it displays -N-C; When the temperature exceeds the range, it displays --- C; If the power out of range, it displays --- P.
• Alternate display mode: press switch once again, the two display mode will alternately change (press again to return to the voltage current meter mode)
• State memory mode: Long press the switch more than 1s, the device will set the current display mode as the default boot mode.

• Red thin wire (VCC): power supply+
• Note: If the measured signal is lower than 28V and have abundant power supply, can be directly used as a power supply module (the thin yellow line and the thin red line parallel use)
• Black thin wire(GND): power supply -, Measurement signal -
• Yellow thin wire (VIN): Measurement signal+
• Red thick wire (I+):Current input+ (connect with load negative)
• Black thin wire(I-):Current input-(in series in power supply negative)

• 1x Temp Power Volt Current Multimeter
• 1x 18B20 temperature sensor chip
