maintenance can prolong the service life of the machine and maintain good 

performance. 

(2) 

Cleaning

: Operators should do thorough cleaning, especially the dust and debris that 

adhere to the vents which can be sweep out by brush or compressed air. Operators 

should be careful when cleaning to not open the enclosure.   

(3) 

Check: 

After cleaning, check carefully whether the equipment is in good condition. 

Turn on the power and check measuring instrument and that the fan is in good condition. 

If no abnormal issues then start the testing.   

(4) 

Ventilation: 

Operator should turn on the power to check the performance of the fan. 

If the cooling fan is abnormal or there is air duct blockage, it could cause the machine to 

overheat.   

(5) 

No-load running: 

If the machine is stored for a long time, it is recommended to first 

let the machine run without load, while not connected to the device under test. 

Components heat will disperse moisture to ensure that the device performance is stable 

and reliable. In areas where the air humidity is high, no-load running on a regular basis is 

an effective measure to reduce equipment failure.   

 

6.3 Troubleshooting 

 

Please see the below table for common issues and their possible solutions. If the 

problem you encountered is not listed here, please contact Eagle Eye Power Solutions, 

LLC for support. 

 

Problem 

Possible reasons 

Solutions 

The machine does not 

start 

Power supply is not 

connected 

Check the device wiring is correct, and check 

whether the local power supply is powered. 

Automatic shutdown after 

starting 

Power anomalies 

Check if the voltages of input working power supply 

is correct 

Abnormal fan rotation 

Power supply not steady 

Provide the steady power supply 

Lack of fan flow, poor 

heat 

dissipation 

Vents or fan blockage 

Check the vents and fan if there is debris, sweep 

out. 

Operation no response
