The thermo-hygrometer draws power from the provided power adapter. Plug the adapter 

into a wall outlet of the appropriate voltage and insert the DC plug into the DC power 

input of the thermo-hygrometer. 

Power is turned on and off with the power switch located below the stand on the back 

panel. To switch the power on, toggle the power switch to the   position. To switch power 

off, toggle the power switch to the   position. The instrument takes a few seconds to 

power up, initialize, and begin normal operation. A self-test is performed, displaying the 

channel configuration and status of the system, calibration, % battery power, memory, 

and buttons. If the thermo-hygrometer calibration has expired and the alert message is 

enabled, the user is notified and must press the E button to continue initialization. If an 

error message is displayed on power up see Troubleshooting. 

After initialization, the temperature and relative humidity measurements for the enabled 

channels are displayed. If recording is enabled, the measurements will be automatically 

stored in memory. The display can be configured to display the measurements in a 

variety of numerical and graphical formats. For information on the various modes of 

operation of the thermo-hygrometer, see Menu Functions.
