■Function Introduction
The meter measures the DC current value, and the upper limit and lower limit can be set. When the measured value is greater than or equal to the upper limit, the upper limit alarm relay OUT2 outputs, and when the measured value is less than or equal to the lower limit value, the lower limit alarm relay OUT1 outputs, the measured value When between the upper limit and the lower limit, the relay does not output.
Generally, when the measurement is between the upper limit and the lower limit, it is qualified, and when it is greater than the upper limit or less than the lower limit, it is unqualified.If necessary, you can set the relay OUT1 as a qualified output and the relay OUT2 as an unqualified output by setting the instrument parameters.
