1. The ambient temperature of the instrument is -40~70°C, the relative humidity is not more than 80%. If the deviation is 20±5°C from the normal use temperature, the pressure gauge must be included in the temperature additional error.
2. The meter must be installed vertically and strive to maintain the same level as the measuring point. If the difference is too high, the additional error caused by the liquid column is not necessary. When installing, block the explosion-proof port at the back of the case to avoid affecting the explosion-proof performance.
3. The measuring range for the normal use of the meter: 3/4 of the upper limit of the measurement under static pressure, and should not exceed 2/3 of the upper limit of the measurement under fluctuation. Under the above two pressure conditions, the maximum measurement of the large pressure gauge should not be less than 1/3 of the lower limit, and the vacuum portion is used when measuring the vacuum.
4. In case of failure when the instrument pointer fails or the internal parts are loose and cannot work normally, it should be repaired or contact the manufacturer for repair.
5. The instrument should avoid vibration and collision to avoid damage.
The JUK universal Screw Terminal Block series has the typical features which are decisive for practical applications:
l The universal foot allows the terminal blocks to be easily snapped onto the NS35 or NS32 DIN Rail with G shape.
l Closed screw guide holes ensure screwdriver operation perfect.
l For terminal block with different wire cross-sectional areas, complete accessories are available, such as end plates, partition plates, etc.
l Potential distribution achieved by fixed bridges in the terminal center or insertion bridges in the clamping space.
l Same shape and pitch Grounding Terminal Blocks as the JUK universal series.
l Adopt ZB marker strip system,achieve unified identification.
