Compact and lightweight designCode ExamplesThe following code examples demonstrate how to use the UNI-T UT33D multimeter in various contexts.### Example 1: Measuring Voltage and Current using Python and pySerialThis example uses Python with the pySerial library to read voltage and current measurements from the UT33D multimeter.```
import serial
import time# Open the serial connection to the multimeter
ser = serial.Serial('COM3', 9600, timeout=1) # Replace COM3 with your device's serial portwhile True:
# Send a command to the multimeter to take a measurement
ser.write(b'MEAS:VOLT:DC?
')
voltage_response = ser.readline().decode().strip()
voltage_value = float(voltage_response.split(',')[0])
print(f'Voltage: {voltage_value:.2f} V')ser.write(b'MEAS:CURR:DC?
')
current_response = ser.readline().decode().strip()
current_value = float(current_response.split(',')[0])
print(f'Current: {current_value:.2f} A')time.sleep(1) # Take a measurement every 1 second# Close the serial connection
ser.close()
```### Example 2: Measuring Resistance using an Arduino and UT33D LibraryThis example uses an Arduino board with the UT33D library to measure resistance using the multimeter.```
#include <UT33D.h>UT33D multimeter;void setup() {
Serial.begin(9600);
multimeter.begin();
}void loop() {
float resistance = multimeter.measureResistance();
Serial.print("Resistance: ");
Serial.print(resistance);
Serial.println(" ohms");delay(1000); // Take a measurement every 1 second
}
```### Example 3: Measuring Frequency using a Raspberry Pi and PythonThis example uses a Raspberry Pi with Python to measure frequency using the UT33D multimeter.```
import serial
import time# Open the serial connection to the multimeter
ser = serial.Serial('/dev/ttyUSB0', 9600, timeout=1)while True:
# Send a command to the multimeter to take a measurement
ser.write(b'MEAS:FREQ?
')
frequency_response = ser.readline().decode().strip()
frequency_value = float(frequency_response.split(',')[0])
print(f'Frequency: {frequency_value:.2f} Hz')time.sleep(1) # Take a measurement every 1 second# Close the serial connection
ser.close()
