Battery-Powered Digital Pressure Gauges APPLICATIONS Process Control Test and Measurement FEATURES 0.25% Test Gauge Accuracy 316 Stainless Steel Sensor Long Battery Life Rugged Design 0-15 psig to 0-1000 psig, and -30 in Hg to 100 psi The SenSym ICT Digital Pressure Gauge Series devices are designed for pressure applications that involve measurement of any media compatible with 316 stainless steel. With its common 1/4" NPT fitting, the device is designed for many applications requiring precision, ruggedness and reliability combined with a long battery life. The digital readout provides real-time information at the push of a button. Designed for battery operation, this digital gauge has an automatic shutoff feature allowing the user to walk away after taking a reading. The SenSym ICT Digital Pressure Gauge Series is designed for long-term usage. Zero and Span calibration are both possible, but only when the user has access to a reliable pressure reference of known accuracy.

Do not tighten it by turning housing! Use fittings designed for the pressure range of the gauge. Do not apply vacuum to gauges not designed for vacuum operation. Operation Press the round button on the front of the gauge to activate the display. The gauge will stay on for 5 minutes. After this time, the gauge will automatically shut off. The gauge can be shut off at any time by pressing the button again. "LOBAT" will appear in the upper left-hand corner of the display when the battery voltage falls sufficiently. The battery should be replaced soon after the LOBAT indicator comes on or unreliable readings may result.

The Zero and Span controls are noninteractive. The gauge port must be open to the ambient with no pressure or vacuum applied. Adjust the Zero control until the gauge reads zero with the minus (-) sign occasionally flashing. Span calibration should only be attempted if the user has access to a pressure reference of known accuracy. The accuracy of the calibration equipment ideally should be at least four times the gauge accuracy. Zero calibration must be done before span calibration. Record readings at three to five points over the range of gauge and adjust span control to minimize error and meet specifications. Battery Replacement Remove the six phillips head screws on the back of the unit. Carefully remove batteries from the holders by lifting up the positive end of the battery (opposite the spring). Take care not to bend or distort the battery retention springs. DO NOT discard the old battery into fire, any other sources of extreme heat, or in any other hazardous manner. Always replace both batteries at the same time with high quality alkaline batteries. Observe the polarity of the batteries when replacing them. The negative (flat) end of each battery should be inserted first and should face the spring in the battery holder. Replace the back cover, including the rubber sealing gasket.
