Soldering Process

See the solder profile on page 2.

Wash

Ultrasonic cleaning is not recommended

Notes:

1) Initial calibration @ 25°C.

2) Frequency vs. temperature stability

3) At the time of shipment after48 hours of operation.

4) Inclusive of calibration, operating temperature range, supply volta ge change, load

change, shock and vibration, 20 years aging.

5) Measured @ 25°C, within 5 minutes, the unit will be within +/-0.1ppm of its reference

frequency, measured after 30 m inutes of continuous operation at a st able 25°C
