In the experiment, some faults often occur on the equipment, which makes the experimenter encounter some problems in the work.

First, the experimenter used a constant temperature shaker.

The first is to be familiar with the basic tools and appearance of the lower shaker.

The second is to learn the performance and basic operation of the shaker.

The third is to know the experimental requirements, and the equipment usage capacity.

Solve the most common problems in the constant temperature shaker equipment in the experimental work and study, and master the small problems of solving the experimental phenomenon.

First, the tray does not run LCD screen without display:

1. The external power supply is not connected. The power plug is plugged in: whether the outlet has power: whether the power switch is turned on.

2. The fuse is burnt. Replace the fuse of the same specification.

Second, the tray does not work, the LCD screen is not normal or the buttons are not sensitive:

1. There are high-frequency interference sources on the same line: press the “Set” button to restore the display and clear the same line interference source.

Or set up a dedicated line or turn off the main power, and turn it on again after a few minutes.

Third, the tray does not run LCD screen has display:

1. Poor contact of the door switch (limited to desktop models) When the emergency occurs, the two wires can be shorted, so you need to inform the company.

Fourth, the temperature fluctuations are large:

1. Open the door frequently, try to reduce the number of door opening and shorten the door opening time.

2. The instrument is placed unevenly. Adjust the front wheel of the instrument to make the instrument land smoothly.

No, the instrument is noisy

1. Loose porous tray: Tighten the fastening nuts at the four corners of the tray.

2. The flask clamp is loose; remove the tray and tighten the flask clamp nut with the attached tool.

Sixth, the measured temperature is too high and often enters the over-temperature alarm state

1. The temperature of the starting control is too high; open the vent of the instrument, if the instrument is used for a long time, please dry it thoroughly.

Seven, the point function disappears:

1. The battery is exhausted; cut off the phone and replace the battery.

2. Run less than 1 minute; ensure that the running time is greater than one minute.

Tianjin Ou Nuo Instrument Co., Ltd. has a lot of experimental equipment to master these functions and attention. In the experimental work, these small problems can be solved.
