1. What are the general working conditions of the thermometer and hygrometer?
* The effective range of temperature is: -30 ° C ~ tinplate 50 ° C or -20 ° C ~ 60 ° C
* The effective indication range of humidity is: 0%RH~100%RH or 10%RH~100%RH
* The use environment is an indoor static indication, and there must be no vibration after hanging.
2. What is the general temperature error of the thermometer and hygrometer?
* Temperature error is less than ±1 °C (10 °C ~ 30 °C), ±1.5 °C (other temperature range)
3. What is the general humidity error of the temperature DIN cup hygrometer?
* Humidity error is less than ± 5% RH (40% ~ 75%), ± 7% RH (20% ~ 40%), ± 9% RH (other humidity range)

However, it may cause deviations in reading due to transportation vibration. If there is any doubt about the display of the agitator, and When the error within the effective indication range is greater than the technical index value, it can be observed together with the reference material in the windless small environment (after about 30 minutes, the longer the time is, the more accurate), and the adjustment is performed after confirmation.
5. How to adjust the hygrometer (table)?
* Cover a wet towel on the back of the hygrometer or the entire color wheel for about 30 minutes. The hygrometer should display a humidity reading of 95% RH. If the pointer fails to point to 95% RH, use a flat-blade screwdriver of the right size and rotate it to the left and right corresponding humidity adjustment holes until the pointer points to 95% RH.
6. How to adjust the thermometer (table)?
* Use a thermometer that has been confirmed to be accurate. Use a suitable size grinder screwdriver to adjust the temperature adjustment hole on the back side to the left and right until the pointer points to the same reading.
