This multimeter measures voltage, current, resistance, temperature, continuity, and diode test, making it an ideal component for a wide range of projects, from robotics to home automation.Technical SpecificationsMeasurement Range:
+ Voltage: 0-600V AC/DC
+ Current: 0-10A AC/DC
+ Resistance: 0-20M
+ Temperature: -20C to 1000C
Accuracy: 0.5% for voltage and current, 1% for resistance
Sampling Rate: 3 times per second
Communication Interface: USB, RS-232, and I2CCode Examples### Example 1: Basic Voltage Measurement using ArduinoIn this example, we'll use an Arduino board to read voltage measurements from the MECO-603 Digital Multimeter.```cpp
#include <Wire.h>#define MECO603_I2CADDR 0x1E // I2C address of the MECO-603void setup() {
Serial.begin(9600);
Wire.begin();
}void loop() {
Wire.beginTransmission(MECO603_I2CADDR);
Wire.write(0x01); // Select voltage measurement function
Wire.endTransmission();
delay(100); // Allow the multimeter to settle
Wire.requestFrom(MECO603_I2CADDR, 4); // Request 4 bytes of data
int voltage = Wire.read() << 8 | Wire.read(); // Read high and low bytes of voltage measurement
float voltageValue = (voltage / 100.0); // Convert to volts
Serial.print("Voltage: ");
Serial.print(voltageValue);
Serial.println(" V");
delay(1000); // Wait 1 second before taking the next measurement
}
```### Example 2: Current Measurement using Python and PyserialIn this example, we'll use Python and the Pyserial library to read current measurements from the MECO-603 Digital Multimeter connected via RS-232.```python
import serial
import time# Initialize the serial connection
ser = serial.Serial('COM3', 9600, timeout=1) # Replace COM3 with your serial portdef read_current():
ser.write(b'CURR?
') # Send command to read current measurement
time.sleep(0.1) # Allow the multimeter to respond
response = ser.readline().decode().strip()
return float(response)while True:
current_value = read_current()
print("Current: {:.2f} A".format(current_value))
time.sleep(1) # Wait 1 second before taking the next measurement
```### Example 3: Temperature Measurement using Raspberry Pi and PythonIn this example, we'll use a Raspberry Pi and Python to read temperature measurements from the MECO-603 Digital Multimeter connected via USB.```python
import usb.core
import usb.util
import time# Find the MECO-603 device
dev = usb.core.find(idVendor=0x03EB, idProduct=0x6124)# Set the active configuration
dev.set_configuration()while True:
# Send the command to read temperature measurement
dev.write(0x01, b'TEMP?
')
# Read the response
response = dev.read(0x81, 64, 100)
response_str = response.tobytes().decode().strip()
# Extract the temperature value
temperature_value = float(response_str.split(':')[1])
print("Temperature: {:.1f} C".format(temperature_value))
time.sleep(1) # Wait 1 second before taking the next measurement
```These examples demonstrate the versatility of the MECO-603 Digital Multimeter and its ability to integrate with various microcontrollers and programming languages.
