Chapter 5 Troubleshooting 

 

Possible  faults  in  use  of  UT1000X  and  troubleshooting  methods  are  listed  below.  Please  handle  fault  as  the 

corresponding steps. If it cannot be handled, please contact with the distributor or local office and provide the 

model information (press Utility 

System

 About to check).

 

 

5.1 

No Display on Screen(Blank Screen) 

 

If the waveform generator is blank screen when press the power switch on the front panel. 

1) 

  Inspect whether power source is connected well.

 

2) 

 

Inspect whether power button is pressed.

 

3) 

 

Restart the instrument

4) 

  If  the  instrument  still  can’t  work,  please  contact  with  the  distributor  or  local  office  for  product 

maintenance service.

 

 

5.2 

No Waveform Output 

In correct setting but the instrument has no waveform output display.

 

1) 

  Inspect whether BNC cable and the output terminal is connected well

 

2) 

 

Inspect whether CH1, CH2 button is turned on

3) 

  If the instrument still can’t work, please contact with the distributor or local office for product 

 

maintenance service.

Maintenance and Cleaning

 

(1)

 

General Maintenance 

Keep the instrument away from the direct sunlight. 

    Caution     

Keep sprays, liquids and solvents away from the instrument or probe to avoid damaging the instrument 
or probe. 

 

(2)    Cleaning 

       

Check  the  instrument  frequently  according  to  the  operating  condition.  Follow  these  steps  to  clean  the 

external surface of the instrument: 

a. Please use a soft cloth to wipe the dust outside the instrument. 

b. When cleaning the LCD screen, please pay attention and protect the transparent LCD screen.
