Dual Display LCD Multimeter Voltage Current Power Capacity Resistance Time Meter

Description

Header Features:
1, 16-bit ADC chip to do the voltage and current, 40V range resolution of 0.6mV, mantissa basically does not shake
2, single-chip high-speed microcontroller selection STC15 series
3, long power CJ431 do voltage reference
4,5 milliohms Kang copper do current sampling (loss)
5, resistors are made of 1% precision chip resistors
Basic parameters:
1, Voltage range: 0-40V
2. Current range: 0-10A
3, the power values: 0-1KW
4, the resistance value: 0-10KΩ
5, AH statistics: 0-99AH
6 stopwatch: 0-99 hours
7, the supply voltage: DC5V [prohibited overpressure]
8, the measurement accuracy: 0.5%
9, PCB Size: 36 * 50mm (1602 for the standard size)
First, the wiring methods:
Second, the LCD contrast adjustment:
If you find that the contrast of the LCD screen does not fit, you can adjust the potentiometer to change yellow, you have a small hole behind the PCB can be stretched with a small flat-blade screwdriver adjustment, side adjustment while observing until the appropriate date.
Third, the mode switching:
Press and hold the button energized, you can enter the mode selection, click Select, often by entering
Among them:
mode 1: Power Resistors mode
mode 2: AH statistical model [In this mode, click: Start / Pause, often by clearing]
Mode 1 and Mode 2 After selecting the automatic save, the next power continue to run the last mode
mode 3: fine tuning mode
mode 4: correction mode
Behind two modes do not enter, if not carefully into the power failure can not affect internal data
Package Included:
1x 1602 LCD (yellow green screen )
1x LCD Dual Display Multimeter
