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
