Manual Conventions This manual is intended to provide the user with the basic information necessary to operate a PDR1000 (Digital Pressure Gauge). It also includes a great deal of additional information provided to allow you to optimize PDR1000 use and take full advantage of its many features and functions. “Caution” is used in throughout the manual to identify conditions or actions that could cause harm to the PDR1000 or user of the PDR1000. “Note” is used throughout the manual to identify operating and applications advice and additional explanations. High pressure liquids and gases are potentially hazardous. Energy stored in these liquids and gases can be released unexpectedly and with extreme force. High pressure systems should be assembled and operated only by authorized personnel who have been instructed in proper safety practices. 27

Introduction The PDR1000 Series Reference Digital Pressure Gauges (the Product) are high accuracy digital pressure test gauges. PDR1000 has best performance that can measure precision pressure from -100 kPa to 500 MPa without a separate external power supply in anytime any place, including on-site and laboratory. Also PDR1000 equipped solid and stylish aluminum outer casing for durability. PDK produced PDR1000 with PDK’s unique pressure calibration and production technology that has best performance in its class. PDR1000 is digital pressure gauge for precise pressure measurement and test with Built-in various features. Simply use buttons on front panel to operate and select various functions and external power input section, analog output port (1 to 5 VDC), and communication port (RS232) and batteries change socket on rear panel. Combine pressure comparator or hand pump for using pressure calibrator in field and calibration lab for simple pressure measurement and calibration provides an excellent solution. 28

5.1 Zero Adjustment Using PDR1000 for a long time, it occurs Zero point change because of yearly variation for pressure sensor and PCB components or other environmental condition. If user wants to set Zero, use Calibration Zero function on CAL Function. 5.2 Pressure Calibration PDR1000 is reference pressure measuring gauge. It needs calibration by authorized organization every year if user wants to maintain PDR1000 guaranteed accuracy. Change the slope value with calibration function to changed pressure correction for PDR1000. 5.3 Analog Output Calibration D-SUB terminal on back side of PDR1000 has various analog output for 0 ~ Full Scale pressure value. If output became incorrect because of long time use, calibration output via RS232 communication program is possible. 46
