Fine-tuning the Pulse One for your Grow

The Pulse One comes with one of the most accurate sensors on the market, and pre-calibrated from the factory. Read why you probably do not need to do a calibration.

Before Getting Started

1. Confirm that your Pulse is placed in the right spot in your grow

2. Confirm that your Pulse is on AC power (not batteries).

3. Get an accurate thermometer and hygrometer - the "standard" that you'll be calibrating to.

4. Make sure that the Pulse and whatever meter you are calibrating it with have been in your environment for at least 24 hours to account for measurement hysteresis.

5. Make sure that the meter you are calibrating the Pulse with is directly adjacent (pretty much touching) the Pulse, and has been there 24 hours. There can be big differences in temperature and humidity for sensors that are even 1-2 feet apart.

6. If you have any calibration settings already, wipe them out at the device's settings page (see step 1 in procedure below).

Calibration Procedure

NOTE: If the device you are calibrating is on batteries, you have to wait at least 10 minutes between calibrations to see the new data. It is strongly suggested to have the device on AC power while calibrating.

1. Click on the device in the dashboard

2. Click on the settings tab above the chart

3. Calibrate the temperature first by either typing in a value or pressing the up and down arrows. Click out of the field or press enter if you were typing.

4. You should see this pop up if successful:

5. Wait 3 minutes (13 minutes if on batteries), this lets the device collect the newly calibrated data (since it takes into account the dew point, humidity will change as well).

6. Refresh the page.

7. Enter the humidity that you want to calibrate the pulse to in the humidity field either by using the arrows or typing in the value. Click out of the field or press enter if you were typing.

8. You should see the success pop up again.

9. Leave the settings page and check the new data after about 3 more minutes (13 minutes if on batteries).

10. Enjoy your newly re-calibrated Pulse. You shouldn't have to re-calibrate for a long time, as the sensor has good temporal stability, however, if the conditions of your grow change significantly (new lighting setup, different HVAC / fans, etc), it might be worth revisiting.
