1. Operating Instructions a Pressure Calibrator Type TGP 2 HH iq Sse Description The TGP2 is a pressure calibrator incorporating an integrated pressure generator and pressure reference both for battery and mains operation Pressure build up is done using a hand pump and for fine adjustment a metal bellows is used 9 Operating Elements 1 ON OFF KEYPAD Power is supplied by connecting the jack connector of the supplied plug in power supply at the back of the housing Using the ON OFF keypad the TGP 2 can be switched on or off If the jack connector is removed the device automatically switches over to battery operation 2 ZERO POINT KEYPAD This keypad is used to adjust the sensor to zero Zero setting must be carried out with the pressure inputs open During zero setting the red LED over the keypad is illuminated Response times are automatically set to the shortest times and must be reset to the required values if necessary 3 MEASUREMENT RANGE KEYPAD Using this keypad the measurement range is selected The LED over the keypad displays the corresponding measurement range value 4 RESPONSE TIMES To suppress pressure peaks the response times of the instrument can be set using this keypad The corresponding integration times are displayed by the LEDs 5 PRESSURE INPUT Measurement input for negative overpressure 6 VENTILATING VALVES This keypad is used to ventilate the measurement set up 7 PRESSU2. RE INPUT Measurement input for positive overpressure 8 PRESSURE OUTPUT P At this output the pressure produced by the pumps or bellows can be tapped and using a T connector can be connected to the test piece or inputs and pressure or inputs of the TGP2 9 LC DISPLAY The measured pressure is displayed on this LED A negative overpressure is indicated with a minus prefix Should the battery voltage be exceeded the battery symbol display is illuminated 10 PUMPS For large displacement volumes a coarse setting of the measured pressure is selected by the pumps Fine adjustment is carried out as in 11 Caution Excessive pressures can damage the measurement cells 11 BELLOWS For small volume displacements as well as for fine pressure adjustments the metal bellows should be preferably be used The metal bellows has two mechanical stops Turning to the right results in a pressure increase whereas turning to the left causes a decrease Never blow into the pressure connections Measurement ranges up to 100 hPa can thereby be damaged or destroyed Directions for the Calibration of Pressure Hdl ld Measuring Transducer using the Type TGP2 Calibrator Description Pe ON OFF NULL 2 00 10 00 3s fs 2s Versorgung TP3 Ausschlag Zeitkonstante Nullpunkt Multimeter Description The pressure output P of the pressure calibrator should be connected via tubi
