0.1 ----when 0.4Vrms≤Vs≤1.2Vrms
，
The measurement speed is medium speed, slow speed and
fast A value.
0.1 ---- when 0.4Vrms≤Vs≤1.2Vrms
，
The measured speed is A value.
when Vs<0.4Vrms or Vs>1.2VrmsA value calculation method is: according to the current
measurement speed selection A, according to the current test signal voltage selection accuracy
correction coefficient A (see figure B) A multiplied by Ar to get the current basic measurement
accuracy A. Here,
Vs is the test signal voltage.
Figure B basic accuracy correction curve test signal voltage
