Field use precautions
1. The on-site use conditions should meet the requirements of the instrument's technical parameters. Correctly select the instrument range, the measured pressure can not exceed the measurement upper and lower limits of the instrument, and there should be sufficient overpressure safety margin.
2. The temperature of the measured medium must not exceed the operating temperature range of the instrument. When using in the place of corrosion and vibration, the sealing and vibration resistance of the instrument should also be ensured.
3, the instrument is directly installed directly downward, can be directly installed on the measured pipe pressure interface, when installed to prevent the instrument connection thread and the front valve to form a "closed pressure" (observe the value, pay attention to the pressure response time) If the pressure is formed, it should be eliminated in time, otherwise it will cause damage to the measuring element and leakage of the medium.
Second, the operating instructions
The sensor and display processing part of the product adopts an integrated design structure. It is easy to use. The instrument and the mechanism to be measured are directly connected by threads, and no requirement is placed on the placement angle of the instrument. Before using the measurement, the approximate pressure range of the measured target should be estimated so as to avoid mechanical damage to the sensor due to excessive pressure beyond the measurement range. The pressure response time of this product is 2S.
Third, on-site environmental considerations
This product is an electromechanical product that uses liquid crystal display technology. Use under strong light will reduce the service life of the LCD screen, and it may make the data unclear. As a result, the factory will not bear any responsibility. The wetted part of the instrument is a stainless steel metal material and a diffused silicon sensor. The media for measuring strong acid and alkali should be selected with a diaphragm type digital pressure gauge. This product uses a non-rechargeable lithium battery. The used battery should be handled properly (mailed back to the factory for a unified treatment) to avoid environmental pollution. When used under high temperature or low temperature (greater than 85°C, less than -30°C), heat sink should be added over 85°C, otherwise the measurement accuracy can not be guaranteed, and the lithium battery has the danger of explosion under excessive temperature conditions. The temperature of the instrument should also be taken into account during storage or transportation. Because this product is an electronic product used in a strong electromagnetic field will cause the instrument to malfunction, resulting in inaccurate indication or simply can not be displayed, but it will not cause substantial damage to the instrument. Different instruments have different pressure measurement ranges. Under normal circumstances, they can be used within 10% of the measurement range. Further over-range use may cause mechanical damage to the sensor, which in turn may cause leakage of the measurement gas or liquid. This damage is not recoverable. , The resulting consequences of the factory does not assume any successive generations of responsibility.
Fourth, failure and exclusion
This product is an electromechanical product. During transportation and use, due to environmental interference, improper use of human operations may cause the instrument to not work and display properly. For simple faults, users can eliminate them. Other faults need to be returned to the manufacturer for repair. The following list shows how to eliminate faults.
Troubleshooting symptoms
No font on the screen to replace the battery
Increase the pressure without changing the font. Remove the battery. Wait 30 seconds before reinstalling the battery.
The font is damaged by non-digital LCD and returned to the factory for repair.
The value is obviously inaccurate. The sensor is damaged and returned to the factory for repair.
Accuracy changes are returned to the factory for recalibration.
Safety harness accessories are thoes stuff which are widely used with safety harness.Such like fall-protection lanyard,carabiners,elastic ropes,buckles,etc.
Lanyard is quite popular equipment,it has various types by different End Fittings.
Carabiners is a connection link which is usually made by steel or high strength aliminum.
They are not the main parts of safety harness,however a safety harness only has more functions with its suitable accessories.
