venTest OPERATORS MANUAL
4.1.1 Power ON
venTest is switched ON using the green ON/OFF button on the rear panel of the display base unit.
The Datrend logo is displayed, internal sensors are initialized and sensor calibration data is
checked. On successful completion, the main window is displayed and the device is ready for
use. External sensors, such as the gas flow sensor, have their own internal memory and maintain
their calibration data independently.
4.1.2 Power OFF/Power Button Menu
To switch the unit OFF, the ON/OFF button is pressed momentarily, causing the Power Menu
screen to be displayed as in Figure 4. To complete the power OFF process, select Shutdown (1).
To cancel, select the Back icon (4).
WARNING:
If the device fails to respond to the request to turn OFF, the
venTest may be switched OFF by pressing and holding the
ON/OFF switch for more than 6 seconds.
This function should only be used in an emergency situation, as it
may result in data loss.
