Adjustment of temperature deviation of on-site temperature display instrument
The adjustment method
1. Rotate the outer ring cover of the dial counterclockwise, open the cover, and gently pry it open with a straight lift (only the part below the gasket that contacts the housing can be pred open with a straight lift (cannot directly pry open the LCD screen glass to prevent damage to the LCD screen)Gently pry up multiple points.
2. After opening, there are "Z" and "S" keys on the back of the LCD screen. If the temperature display deviates from the actual temperature, only the "Z" key can be fine tuned,“S”The keys cannot be adjusted casually.
3. The temperature adjustment must have a standard thermometer as a standard, and the thermometer should be placed in a relatively constant temperature environment. After successful adjustment, it should be placed in a relatively constant temperature environment for 8 hours to stabilize. The temperature deviation displayed by each thermometer should be minimized (0.5% of the range value is the normal deviation). The adjustment method is as follows:
(1) If the actual temperature is higher than the displayed temperature, then rotate the "Z" key clockwise for fine adjustment. If the actual temperature is lower than the displayed temperature, then rotate the "Z" key counterclockwise for fine adjustment. Just enough.
(2) The "S" key must be adjusted by the manufacturer's technical personnel using a debugging instrument, and no other personnel are allowed to use this key.
