Ⅶ Common questions

1, Does the newly purchased thermometer and hygrometer need to be adjusted?

This product has been strictly adjusted and accurate when leaving the factory. Generally, it can be used normally without adjusting it, but it may be due to transportation vibration reasons.When the error within the range is greater than the technical indicator value, you can observe the reference (about 30 minutes) in the non -wind -free and small ring, and adjust it after confirmation.

2, How to adjust the hygrometer (meter)?

The wet towel is covered on the back of the humidity meter or the entire wrap for about 30 minutes. At this time, the humidity meter should show that the amount of humidity is 95%RH.If the pointer fails to point to the 95%RH, use a suitable size screwdriver with a suitable size, and rotate the left and right to the left and right on the corresponding humidity of the back until the pointer is pointed at 95%RH.

3, How to adjust the thermometer (meter)?

Use a thermometer that has been confirmed to be accurate as a reference. Use a flat-blade screwdriver of appropriate size to rotate the corresponding temperature adjustment hole on the back to adjust the pointer reading to be consistent with the reference specimen.

4, What should you pay attention to when using a temperature and humidity meter?

1)  The thermometer and hygrometer should be hung in a well-ventilated place, and avoid hanging on walls exposed to direct sunlight, the air outlet of air conditioners, etc.

2)  The thermohygrometer shall not be installed in a corrosive gas environment.

5, Why does it feel like the thermohygrometer is not working?

What is the reason why the temperature and humidity meter cannot see the pointer change?Is it bad?In fact, the reason is that changes in temperature and humidity are a slow process, and there will be no significant changes in a short time.If you want to know if the pointer is working effectively, you can blow the inner mouth at the breathable hole, or take a hair dryer around the temperature and humidity meter or the breathable holes. Observe the change of the pointer.Time will return to the normal monitored indoor and outdoor temperature and humidity.

6, Introduction to the temperature measurement principle of pointer type thermometer and hygrometer

The pointer temperature and humidity meter uses the principles of two different metals to expand at different degrees of expansion when temperature changes.The main component is a multi -layer metal piece composed of two or more metal slices.In order to improve the temperature sensitivity, the metal sheet is usually made into a spiral roll shape.When the temperature of the multi -layer metal sheet changes, the metal expansion or contraction of each layer of metal varies, causing the spiral rolling or loosening.Because one end of the spiral roll is fixed and the other end is connected with a pointer that can be rotated freely, when the dual metal tablets feel the temperature change, the pointer can indicate the temperature on the one -circular scale.

ⅧDaily basic temperature and humidity range

temperature:

8—15℃, the optimal temperature for grain storage

18—25℃, optimal indoor temperature

ⅨWarm reminder

1.  Because the air in the packaging does not circulate, the value of the product fails to reflect the actual situation in time when it is taken out, and the constant temperature can be placed for half an hour.

2.  In the internal parts of the parts, the shaking will produce a slight sound, which is a normal phenomenon.

3.  Due to the inaccurate or damage caused by the severe vibration, please contact the dealer or manufacturer.
