ACCURACY ±0.5% FS RUGGED ALUMINUM METAL HOUSING ONE TOUCH™ CALIBRATION TECHNOLOGY SERIES 475 DIFFERENTIAL PRESSURE For use with Natural GasBulletin TE-475 SPECIFICATIONS Service:Air and compatible gases. Wetted Materials:Consult factory. Accuracy:±0.5% FS, 60 to 78°F (15.6 to 25.6°C); 1.5% FS from 32 to 60°F and 78 to 104°F (0 to 15.6°C and 25.6 to 40°C). Pressure Hysteresis:±0.1% of FS. Pressure Limits:See chart. Temperature Limits:0 to 140°F (-17.8 to 60°C). Compensated Temperature Limits:32 to 104°F (0 to 40°C). Storage Temperature Limits:-4 to 176°F (-20 to 80°C). Display:4-digit LCD (.425 H x .234 W digits). Power Requirements:9 volt alkaline battery. Battery included but not connected. Weight:10.8 oz (306 g). Process Connections:Two barbed connections for use with 1/8˝ or 3/16˝ I.D. tubing. Two compression fittings for use with 1/8˝ I.D. x 1/4˝ O.D. tubing (for 100 psi or higher pressure ranges). Agency Approvals:CE, FM approved to CLASS 1, DIV. 2 GROUPS ABCD/T4 Ta = 70°C. OPERATING INSTRUCTIONS ON/OFF: Press ON/OFF to turn the unit on. Press and hold ON/OFF for about 2 seconds to turn it off. Device will automatically shut off after 20 minutes if not in use. ZERO: Vent both pressure ports to atmosphere. Press ZERO button until the LCD displays “-----” then release it. The LCD reads 0 if the zero offset is less than 10% of FS. UNITS: To change units, press both ON/OFF and ZERO buttons simultaneously. BATTERY: Remove retaining screws on end cap at base of instrument to replace battery when LOW BAT is displayed. Use 9 V alkaline battery DURACELL® MN 1604, Energizer® 522, or Energizer®EN22.
