3.4.Measureing Condition:

Parts shall be measured under a condition(Temperature:+5°C to +35°C,Humidity:45 to 85% R.H.)

unless the standard condition(Temperature:+25± 3°C,Humidity:60± 10%R.H.)is regulated to

measure.

3.3.Insulation Resistance:

An insulation resistance shall be measured by using an insulation resistance meter,suach as DF2863

insulation resistance meter.

3.2.Capacitance:

An electrostatic capacity capacitance shall be measured at 120Hz by using LCR meter, such as DF2812A

LCR numerical bridge or equivalent.the part shall be clamped at the node .

3.1.Resonant Frequency/Resonant Impedance

piezoelectric diaphragm shall be clamped at a node point as shown in following figure to be free from any

mechanical stress,and measured its resonant frequency and resonant impedance by using

YW2788 synthesis parameter test apparatus or equivalent
