6. Measuring Methods
6-1. Measuring Environment, Meters and Equipment
6-1-1: Environment
Testing and Measuring must be conducted under the environment of the normal
temperature (24+/-2°C) and the normal humidity (65+/-20%RH), if not specified.
6-1-2: Dimensions
For measuring dimension JIS B 7503 (Dial gauge), JIS B 7507 (Vernier caliper)
and JIS B 7502 (External micrometer) or meter with same grade in accuracy must
be used.
6-1-3: DC Voltmeter
Voltmeter with class 0.2 of JIS C 1102 (Electric indicating instrument) or meter with
same or better grade in accuracy, and its input impedance is over 10Mohm must
be used.
6-1-4: DC Ammeter and AC Ammeter
Ammeter with class 0.2 of JIS C 1102 (Electric indicating instrument) or meter with
same or better grade in accuracy must be used.
6-1-5: Resistance
Resistance should include all resistance in external circuit and its tolerance must
be within +/-0.5%.
6-1-6: Initialization of capacitor
All measurements must be conducted after 30 minutes of short-circuit.
6-2. Capacity
6-2-1. Discharge capacity
1) Charging condition:
Charge capacitor by voltage of 3.3V through protective resistance of 100 ohms
for 5 hours.
2) Discharging condition:
Discharge the capacitor by using constant current of 20uA to 2.0V. Then the
capacity is calculated by the duration.
The electrical discharge by the fixed resistance of 100kohm is allowed as
substitution of 20uA in a fixed current ampere. However, the calculation of
capacity must be used the division mensuration.
