I. INTRODUCTION The RJC Model 650 Fiber Optic Measurement System (FOMS) is a microcontroller based Instrument designed to support measurements made using RJC pressure sensor assemblies. The Model 650 is NOT designed or certified for making measurements in humans. The Fiber Optic Measurement System and related sensor assemblies are manufactured by RJC Enterprises, L.L.C., 11711 N Creek Parkway South, Suite D-103, Bothell WA 98011, USA. II.
SPECIAL NOTICE THE MODEL 650-02 FIBER OPTIC MEASUREMENT SYSTEM (FOMS) IS DESIGNED FOR USE WITH SC OPTICAL CONNECTORS ENCASED IN A CLAMSHELL ASSEMBLY. OPTICAL CONNECTORS MUST BE CLEAN TO ENSURE EFFICIENT TRANSMISSION OF LIGHT BETWEEN INSTRUMENT AND SENSOR. The FOMS SC optical connector is composed of two parts: x The male Connector, on the Fiber Optic Pressure Sensor assembly, and x The female Adapter with mating male connector, located within the instrument front panel.

III. OPERATING INSTRUCTIONS 1. SETUP o Place Instrument in a well-ventilated location. o Attach line cord to an appropriate 110 VAC outlet (Note: See section 10 for 220 VAC operation). o If data logging is desired, connect an appropriate cable to the USB digital output (Figure 1). o Switch Instrument power to ON (Figure 1). x A green light (Figure 2) indicates Instrument is ON 2.
o To re-zero a sensor that has already been zeroed, press the Zero button 3 times in less than 2 seconds. Notice: The FOMS Display is for use with static pressure measurements only. For dynamic pressure measurements, the USB output must be used. 5. DEALING WITH THE TEMPERATURE SENSITIVITY OF PRESSURE SENSORS Almost all pressure sensors have some sensitivity to temperature change, e.g.
‘stream??’ o When a sensor is attached to the Instrument and has been zeroed, the Instrument will output differential pressure readings to the USB port at a rate of 1000 samples per second. o Each line of streaming data will contain: a sign for negative values, differential pressure in 1 count per 0.1 mmHg, a comma separator, a sequence decimal digit, and two hexadecimal digits that encode a CRC8 value for the previous characters on the line.
o If not already present, install fuses into block (note - two European fuses are required). o Reinstall fuse holder block. Note – the European fuses go into the power module first. o Close the fuse holder door. 11. CALIBRATION For optimal performance, the Model 650 FOMS should be returned to RJC for annual calibration. 12. x x CLEANING THE FEMALE OPTICAL ADAPTER RJC recommends the operator blow out the SC adapter with compressed air between every connector insertion.
Step Action Carefully pull the optical Adapter forward. A pair of needle nose pliers may be helpful in grasping the adapter. Note the orientation of the key slot (up) ( p) and spring p g clip (back). 2 After pulling the adapter clear of the instrument, gently remove the internal male connector from the adapter, being careful not to touch or bump the end/tip of the connector. Set the fiber assembly/connector to the side where it will not be damaged.
IV. DIAGNOSTIC MESSAGES The following messages will appear on the FOMS LED display. Message Reason for Message Suggested Action USB Output Instrument not warmed up. x Allow Instrument to warm up for approximately 10 minutes.
V. WARNINGS The RJC Fiber Optic Measurement System (FOMS) will operate safely and accurately if instructions are followed. x Use of Sensors other than those manufactured by RJC Enterprises can lead to erroneous measurements and/or Instrument malfunction. x The pressure Sensor must be zeroed before use; follow operating instructions given above. x The FOMS Instrument must be connected to a grounded, 110/220 VAC, 50/60 Hz power source.
