====== OpenLogger - Calibration ======

===== First-Time Calibration =====

Before being used for the first time, a new OpenLogger must first be calibrated. This process determines constants used to accurately calculate analog voltages for data points being logged, and stores these constants in non-volatile memory.

**Note:** //After first-time calibration, described in this guide, a device can be recalibrated, if desired, through its Configuration Menu, found through the Device Manager in WaveForms Live.//

=== 3. ===
Connect the red wire on pin 6 (DC OUTPUT 1) to the solid orange wire on pin 35 (Analog Input 1). Take a look at the [[test-and-measurement:openlogger:reference-manual#openlogger_pinout|OpenLogger Pinout]] in the Reference Manual for details on which wire corresponds to which OpenLogger pin.
