Note: Accuracy is given as ±(% of reading + counts of least significant digit) at 23°C
±5°C, with relative humidity less than 80%RH. The measured conductorbis placed in the
center of the coil.
Output Noise: <5.5 mV for each range.
Max. output voltage: 5.8 V. If the output voltage is greater than 3 V, the results indicate
that the measurement has been out of range and not to be used as indicator assessment.

6. Operation

6-1 AC Current Measurements
Turn on the instrument power supply, insert the output line of the meter into the input
end of the high precision digital universal meter with AC voltage measurement function.
Pre-estimate the size of the current to obtain the best output signal and choose a good
measurement of gear. Single phase and then measured the ring into the flexible coil,
placed in the central position, and completely closed. This can be converted to obtain the
magnitude of the current value.
