How is the accuracy level of DIN Rail Power Meter divided?

The accuracy level of DIN Rail Power Meter is similar to that of general industrial instruments. According to relevant national standards such as "GBT 13283-2008 Accuracy Level of Detection Instruments and Display Instruments for Industrial Process Measurement and Control", the common divisions are as follows:

0.01 level: It belongs to the extremely high accuracy level, and the allowable error is ±0.01% of the upper limit of the measurement range or the range. It may be used in some ultra-high standard scientific research experiments, extremely precise power metering and other occasions. The accuracy requirements for power parameter measurement are extremely high, and almost no error is allowed.

0.02 level: The allowable error is ±0.02% of the upper limit of the measurement range or the range. It is generally used in high-end scientific research, ultra-precision manufacturing and other fields with extremely demanding measurement accuracy, such as aerospace power system parameter measurement.

0.05 level: The allowable error is ±0.05% of the upper limit of the measurement range or the range. It can be used in some calibration laboratories with very high requirements, as a high-precision standard measuring instrument, to provide a calibration basis for other lower-precision instruments.

Grade 0.1: The allowable error is ±0.1% of the upper limit of the measurement range or the range. It is often used in scenarios with high accuracy requirements such as standard measuring instrument calibration in power measurement laboratories and high-precision scientific research experiments.

Grade 0.2: The allowable error is ±0.2% of the upper limit of the measurement range or the range. It can be used in high-precision industrial measurement occasions, such as large-scale precision manufacturing plants for accurate measurement of power parameters of key production equipment.

Grade 0.5: The allowable error is ±0.5% of the upper limit of the measurement range or the range. It is widely used in general industrial site monitoring, ordinary power system monitoring and other scenarios, and can meet the basic and accurate measurement requirements of power parameters in daily life.

Grade 1.0: The allowable error is ±1.0% of the upper limit of the measurement range or the range. It is suitable for occasions where the accuracy requirements are not particularly high and are mainly used to roughly understand the power parameters, such as simple monitoring of small non-critical power equipment.

Level 1.5: The allowable error is ±1.5% of the upper limit of the measurement range or the range. It is generally used in some industrial measurement scenarios where the accuracy requirements are not very strict, such as general monitoring of the operating status of ordinary factory power equipment.

Level 2.5: The allowable error is ±2.5% of the upper limit of the measurement range or the range. It can be used in occasions with relatively low accuracy requirements, such as monitoring of some auxiliary production equipment with low requirements for power parameter accuracy.

Level 4.0 and above: The accuracy is relatively low and the allowable error is large. It may be used in some very common occasions where only a general understanding of power parameters is required and the accuracy requirements are extremely low.
