1. During storage, installation, use, and transportation, WSS series bimetallic thermometers should be protected from impact, and the protective tube should not be bent or deformed. During installation, do not twist the instrument casing.
2. The instrument should operate normally within an ambient temperature range of -30℃ to 80℃.
3. The ideal operating temperature for the instrument is preferably within 1/2 to 3/4 of the scale range.
4. The immersion length of the bimetallic thermometer's protective tube in the measured medium must be greater than the length of the temperature-sensing element. Generally, the immersion length should be greater than 100mm, and for the 0-50℃ range, the immersion length should be greater than 150mm, to ensure measurement accuracy.
5. Bimetallic thermometers are not suitable for measuring the temperature of media in open containers. Electrical contact thermometers should not be used in control circuits in environments with significant vibration.
6. During storage, use, installation, and transportation, avoid impacting the protective tube of the bimetallic thermometer, and do not bend or deform the protective tube or use the instrument as a wrench.
7. The thermometer should be inspected regularly under normal use. Generally, every six months is recommended. Electrical contact thermometers should not be operated under strong vibration to avoid affecting the reliability of the contacts.
