故障一 开机后,按下Marker开关,连续操作操纵杆1和2,箭头标记和光标移动范围缩小,不能达到应有的宽度范围。根据故障现象,考虑是否由于操纵杆1和2下面的电位器积聚灰尘,造成电位器接触不良所致。用无水乙醇清洗电位器后,开机试验,故障排除。 故障二 开机后,按下Marker开关,操作操纵杆1和2,箭头标记和光标均无显示。有时开机后,又可在监视器的左上角或右下角显示箭头标
After the fault is turned on, press the Marker switch and operate the joysticks 1 and 2 continuously. The arrow marks and the cursor movement range are reduced and the width cannot be reached. According to the phenomenon of failure, it is considered whether or not the potentiometer is in poor contact due to accumulation of dust by the potentiometers below the joysticks 1 and 2 . After cleaning the potentiometer with absolute ethanol, start the test and troubleshoot. Fault 2 After turning on the power, press the Marker switch and operate joysticks 1 and 2 with no arrow marks or cursors displayed. After turning on the power, you can also display the arrow in the upper left corner or the lower right corner of the monitor.
