2 SAFETY Operate dry-blocks in an ambient temperature between +50°F and 86°F (+10 and +30°C) (+15 to +25°C for optimum accuracy) and humidity between 5 to 95% (non condensing). Note: High humidity will cause icing of the well when operated below zero. The fan runs continuously to moderate the internal unit temperature. Always ensure the air vents and fan aperture are clear and have at least 6 inches (150mm) of space between them and any obstructions.
3.2 Operation 3.2.1 Dry-Block Set-Up Place the dry-block unit on a flat level surface with at least 6 inches (150mm) of space in front and behind. The stand may be swung out to lift the front of the unit. Plug the power cord into a suitable grounded AC power outlet socket. Check for and remove any foreign objects prior to switching on. Turn the instrument on using the switch located on the rear panel, below the power cord.
