Matters needing attention
1,The measuring medium cannot be frozen;
2,During installation, avoid scratching the O-ring seal;
3,Do not use media beyond the prescribed limits;
4,The power supply needs to be filtered to prevent damage to this product caused
by instantaneous high currents;
5,Please do not exceed the specified range of power supply voltage;
6,It is strictly prohibited for cables to bear tension;
7, Avoid falling, hitting, and puncturing hard objects;
8,Avoid product exposure to water and strictly prohibit water immersion;
9,It is strictly prohibited to disassemble the casing to avoid product damage.
Disclaimer
1,Use of media beyond regulations;
2,Exceeding the specified power supply voltage for use;
3,Use beyond the specified temperature range;
4,Use beyond the specified pressure range;
5,Severe deformation or damage to the isolation membrane caused by improper operation;
6,Force majeure, such as product damage caused by lightning strikes, etc;
7,Other product damage caused by failure to use in accordance with the requirements of this specification.
Note: The accuracy of a product refers to the error rate between the theoretical output value (calculated according to the output formula) and the actual measured value.
That is, accuracy=(measured value - theoretical value)/net output
Net output: 4.5-0.5=4
