______________
Remove the device from the socket before executing this command. Voltages will be applied to certain pins,
and this may damage the device.
11.4.1 System Test
This selection is used for testing pins function which is I/O input, GND output, VCC output, VPP output.
Clicking Test button, system will auto test. When something is wrong, it will stop and display the fault pin. If it
passes all tests, it will display ‘System test OK!’
11.4.2 VCC Calibration
This selection is used for testing voltage provided for device. By clicking Test button, voltage between the red
pin and the blue pin should be about 5V or 6--6.5V (Dependent on programmer).Click Stop button, it will exit.
11.4.3 VPP Calibration
VPP0 (VPP1) Calibration: 12V
This selection is used for testing voltages provided for IC to program. By clicking Test button, voltage
between the pale blue pin and the blue pin should be 12—12.5V. Click Stop button & it will exit.
VPP0 (VPP1) Calibration: 25V or 21V
This selection is used for testing voltages provided for IC to program. By clicking Test button, voltage
between the green pin and the blue pin should be 25V. Click Stop button & it will exit.
11.4.4 Output test
This selection is used for testing programmer output logic.
Note that it needs a ‘Test Board’ on socket. Test Board is a short-circuit board. For example, P1 pin is
short-circuited with P48 pin. P2 is short-circuited with P47 pin. By clicking Test button, it starts testing. If Test
Board is not on the socket, it will note that ‘Error! No ‘Test Board’ on the socket!’.
