Page 4: Installation
INSTALLATION DESCRIPTION OF THE SP-MODULE The SP-MODULE is capable of measuring low pressures with a ±1% accuracy - ideally suited for proper building pressurization and air flow control. Transmitters can withstand up to 10 psig overpressure with no damage to the unit. Variable capacitance sensor design provides excellent sensitivity and long-term stability. - Page 5 SP-MODULE Fig. 1 Exploded view of the SP-MODULE Do NOT install or use a damaged module. Contact your distributor to obtain another unit. Take a few moments to write the complete serial number found on the side of the module on page 1 of this manual. This will be useful for future reference.

Page 8: Connecting The Output Wire
- When extending an output wire, solder all connections. - Never run low voltage cables parallel to high voltage wires to prevent interference. - Output cables must cross power cables at a 90° angle. ALWAYS switch power to the sensor OFF before opening the sensor. SP-MODULE rev.04... -
Page 9: Using The Sensor
Whenever possible, any zero and/or span offsets should be corrected by software adjustment in the user's control system. Use the zero and span adjustments on the SP-Module (668 Series) only if abso- lutely necessary. The SP-Module (668 Series) is calibrated in the vertical, position the unit and follow the zero adjustement procedure listed below. - Page 10 Span on full scale output adjustments should only be performed by using an accurate pressure standard (electronic manometer, digital pressure gage, etc.) with at least comparable accuracy to the SP-Module (668 Series) (<±1% full scale). With full scale pressure applied to the high pressure port (reference port open to atmosphere) adjust span to achieve 20 mA output.
