CARTA Classic — Everlast Atomizer Calibration

The CARTA Classic uses resistance-based temperature control. If the device is over- or under-heating, manually recalibrating the Everlast Atomizer resets the resistance baseline so the device heats accurately.

Before you start

• An external thermometer or IR temperature reader is required to verify calibration
• The device should be at room temperature — as close to 77°F (25°C) as possible before calibrating
• Ensure the atomizer is clean and connections are free of debris

Calibration steps

1. 1
   Power off and prepare the device

   Ensure the CARTA Classic is powered off and cooled to room temperature. Remove any attachments except the Everlast Atomizer.

2. 2
   Inspect the atomizer and connections

   Gently unscrew the top cap of the atomizer to inspect the heating chamber. Check that the atomizer is securely threaded into the base. Clean any debris from the threading or connection pins with a cotton swab and isopropyl alcohol if needed. Dry completely.

3. 3
   Power on the device

   Press the power button 5 times to power on the CARTA Classic.

4. 4
   Access calibration mode

   Press the power button 4 times consecutively. On the 4th press, hold the button down until the device enters calibration mode. The LEDs will indicate calibration mode has been activated.

5. 5
   Follow on-device prompts

   Watch the LED patterns for guidance. The device will automatically adjust resistance based on the atomizer's current state. Follow any specific LED sequences indicated.

6. 6
   Complete and verify

   Release the power button once calibration is complete. The LEDs will confirm successful calibration.

7. 7
   Test the calibration

   Reassemble the atomizer and fire a session. Use your external temperature reader to verify the actual temperature matches the target. If not within range, repeat the calibration process.
