Low battery indication and automatic shutdownTechnical SpecificationsPower supply: 1.5V x 2 (UM-2 or AA)
Operating temperature: 0C to 40C
Storage temperature: -10C to 60C
Dimensions: 145 x 75 x 35 mm
Weight: 220g (without batteries)Communication InterfaceThe MS830L+ Multimeter can be connected to a microcontroller or a computer using a serial communication interface, such as RS-232 or USB. The multimeter transmits measurement data in a formatted string, which can be parsed and processed by the connected device.Code Examples### Example 1: Reading Voltage Measurement using ArduinoIn this example, we will demonstrate how to read voltage measurements from the MS830L+ Multimeter using an Arduino board.```cpp
#include <SoftwareSerial.h>// Define the serial communication pins for the multimeter
#define RX_PIN 2 // Receive pin
#define TX_PIN 3 // Transmit pinSoftwareSerial multimeterSerial(RX_PIN, TX_PIN);void setup() {
// Initialize the serial communication at 9600 bps
multimeterSerial.begin(9600);
}void loop() {
// Send a command to the multimeter to take a voltage measurement
multimeterSerial.println("VOLT:DC?");// Wait for the multimeter to respond with the measurement data
delay(500);// Read the response string from the multimeter
String response = multimeterSerial.readStringUntil('
');// Extract the voltage value from the response string
int voltageIndex = response.indexOf("V=");
float voltageValue = response.substring(voltageIndex + 2).toFloat();// Print the measured voltage value
Serial.print("Measured voltage: ");
Serial.print(voltageValue);
Serial.println(" V");// Wait for 1 second before taking the next measurement
delay(1000);
}
```### Example 2: Reading Current Measurement using Python (PySerial)In this example, we will demonstrate how to read current measurements from the MS830L+ Multimeter using a Python script and the PySerial library.```python
import serial# Open the serial communication port at 9600 bps
ser = serial.Serial('COM3', 9600, timeout=1)while True:
# Send a command to the multimeter to take a current measurement
ser.write(b"CURR:DC?
")# Wait for the multimeter to respond with the measurement data
response = ser.readline().decode('utf-8')# Extract the current value from the response string
current_index = response.find("A=")
current_value = float(response[current_index + 2:])# Print the measured current value
print("Measured current: {:.2f} A".format(current_value))# Wait for 1 second before taking the next measurement
time.sleep(1)
```Note: In both examples, replace the serial communication pins and port numbers with the actual values suitable for your setup. Additionally, ensure that the multimeter is properly configured and connected to the microcontroller or computer before running the code.
