Common faults and solutions of constant temperature shaker

The large incubator shaker has comprehensive functions and a wide range of applications, but occasionally some faults will affect the normal use of users
.

The technical engineer has synthesized the feedback of the majority of users over the years, and summarized the common faults and solutions of the instrument
.

Share it with you here, I hope it will help you
.

1.
The instrument cannot run normally 1.
Check whether the power indicator light is on, if not, it may be caused by power failure, poor contact, damaged fuse,
etc.

2.
If the power indicator is normal, check whether the controller of the instrument is normally turned on and whether the speed parameters are set
.

2.
Abnormal cooling when the instrument is running 1.
If the instrument is not cooling, check whether the malfunction is caused by the damage of the compressor
.

2.
When the compressor is damaged and used again after repair or replacement, the instrument can be set to balance mode
.

The compressor in the balance mode is always working, and the cooling effect is better, and it can be effectively maintained
.

 　　3.
If it is a single-system operation and you want the compressor to work, the temperature of the box must be lowered to below room temperature; if refrigeration is required, in order to ensure the normal operation of the compressor, the set temperature should be at least 5 degrees Celsius lower than the room temperature
.

 　　4.
If the temperature in the box fluctuates greatly during the operation of the instrument, it may be caused by frequent opening and closing of the box door
.

In this case, the compressor will start frequently, which will shorten its service life in the long run
.

Should try to avoid frequent opening and closing of the door during use
.

 　　3.
Abnormal temperature during instrument operation 1.
It may be that the arrangement of shake flasks is too dense, resulting in poor circulation of the circulation vents.
The position of the shake flasks should be adjusted in time to make them evenly and symmetrically distributed
.

 　　2.
It may be due to the long-term use of long-term light, and the heat conduction of the bulb causes the temperature to be uneven
.

 　　3.
Check the instrument box to see if the circulating fan is working normally
.

 　　4.
If the temperature in the box fluctuates too much, it may be caused by the wrong setting of the cooling method
.

The cooling mode should be reset according to the instructions
.

 　　5.
The instrument cannot control the temperature normally
.

Check whether the temperature control switch is turned on.
If it is turned on, then check whether there is a number displayed on the temperature controller and whether the temperature control setting is performed correctly
.

 　　6.
If the instrument cannot be heated normally, it may be caused by damage to the temperature controller or damage to the heating tube
.

It can be dealt with in time after one by one investigation
.

 　　7.
If the measured temperature is high, it may be caused by the high starting and control temperature.
You can click the cooling button or open the ventilation holes of the instrument
