Measuring Instrument or Apparatus
Dimension Measuring Instrument
The dimension measurement shall be implemented by instruments with equal or more precision scale of 0.01mm.
Voltmeter
Standard class specified in the national standard or more sensitive class having inner impedance more than 10kΩ/V
Standard class specified in the national standard or more sensitive class. Total external resistance including
ammeter and wire is less than 0.01Ω.
Impedance Meter
Impedance shall be measured by a sinusoidal alternating current method (1kHz LCR meter).
