The PiggyMeter is designed to meet the needs of a wide range of users, offering robust performance and reliability. Below are its key technical specifications:

The PiggyMeter is designed for ease of use, but proper handling is essential to ensure accurate measurements and safety. Follow the steps below to use the PiggyMeter effectively:

1. Power On: Insert a 9V battery or connect the PiggyMeter to a USB power source. Turn the rotary switch to the desired measurement mode (e.g., voltage, current, resistance).
2. Connect Probes: Insert the black probe into the COM terminal and the red probe into the appropriate terminal (VΩmA for most measurements or 10A for high-current measurements).
3. Select Range: If the PiggyMeter is not auto-ranging, manually select the appropriate range for the measurement.
4. Take Measurement: Connect the probes to the circuit or component under test. Read the measurement on the LCD display.

• Always start with the highest range when measuring an unknown parameter to avoid damaging the device.
• Do not exceed the maximum input ratings for voltage, current, or resistance.
• Use the optical interface or USB connection to transfer data to a computer for logging or analysis.
• Ensure the device is powered off when not in use to conserve battery life.

The PiggyMeter can be used to measure voltage or current in circuits involving an Arduino UNO. Below is an example of measuring the voltage across a resistor in a simple LED circuit.

// Simple LED circuit example for voltage measurement
// Connect the PiggyMeter probes across the resistor to measure voltage.

const int ledPin = 9; // Pin connected to the LED
void setup() {
  pinMode(ledPin, OUTPUT); // Set the LED pin as output
}

void loop() {
  digitalWrite(ledPin, HIGH); // Turn the LED on
  delay(1000);                // Wait for 1 second
  digitalWrite(ledPin, LOW);  // Turn the LED off
  delay(1000);                // Wait for 1 second
}

1. Build the circuit with the Arduino UNO, LED, and resistor.
2. Set the PiggyMeter to DC voltage mode.
3. Connect the probes across the resistor.
4. Observe the voltage reading on the PiggyMeter display.

Q: Can the PiggyMeter measure AC current?
A: Yes, the PiggyMeter can measure AC current up to 10A using the 10A terminal.

Q: How do I enable data logging?
A: Use the optical interface or USB connection to connect the PiggyMeter to a computer. Install the Aquaticus software to enable data logging.

Q: Is the PiggyMeter suitable for high-voltage applications?
A: The PiggyMeter can measure voltages up to 600V. For higher voltages, use appropriate step-down circuits or equipment.

By following this documentation, users can maximize the functionality and lifespan of their PiggyMeter while ensuring safe and accurate measurements.
