1, electrical contact bimetallic thermometer should be installed in the surrounding environment -20 ℃ ~ 40 ℃, the relative temperature of not more than 80%, altitude below 2000m, at the installation site, the monthly average temperature is not higher than +30 ℃, due to temperature changes , Allowing the surface of the thermometer to produce Cream, the measured medium temperature <200 ℃, (if used for steam and other high-temperature medium measurement, should use temperature and electrical contact bimetallic thermometer).
2, the instrument must be installed vertically, and strive to maintain the same level with the measurement point, or should be included in the liquid level caused by additional error.
3, the electrical circuit of the instrument received after the careful inspection and test action.
4, the instrument temperature part of the general use of the upper temperature limit 3/4.
5, adjust the instrument set value (by adjusting the knob, the upper and lower limit set the pointer to the given value) should first adjust the lower limit given value and then adjust the upper limit given value.
6, open the outlet box or adjust the set value range to be cut off after the power.
7, the instrument in normal use, should be regularly checked, at least once a year to show inspection, the instrument in case of sudden accident (leakage, rupture caused by pressure relief, contact welding or due to severe oxidation and affect the contact Reliability, pointer off, loose or instructions such as distortion) should be immediately checked.
