PC FUNCTION GENERATOR Velleman PCG10 DIAGRAMS AND CALIBRATION _______________________________________________________________________________________________________________________________________________________ 1. CALIBRATION To allow calibration, the unit must be connected to the computer and the supplied software must be installed. Please consult the `Getting Started' manual for details on the connection and installation procedure. · Select the function generator module [Function generator]. · Select the correct parallel port [Options > Hardware setup]. · Check if the `POWER ON' (LD1) LED lights. If it does not light, check the complete assembly and check the parallel port settings in the · options-hardware setup of the software. · Make sure the frequency is set to 1000Hz (1KHz). Adjust if necessary. · Make sure the offset is set to 0V. Adjust if necessary. · Make sure the amplitude is set to 5Vpp. Adjust if necessary. · Select sinewave output . Readout should now show a sine wave and the `READY' LED (LD2) should light. · Connect a digital multimeter to the `signal out' connector of the generator. Set it to DC volts. Adjust the multi-turn trimmer RV1 until the multimeter displays zero volts. If necessary, adjust the range of the meter to obtain a higher resolution. Now you can check the wave- form, using an oscilloscope or one of our PC- or handheld scopes IF SPECIAL TEST SOFTWARE IS USED THEN CALIBRATION MUST BE DONE WITH THIS SOFTWARE AND PCS500 SCOPE 2 2.
