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 stabilit y, peak to peak, 0 to 70°C.

3) Inclusive of calibration, operating tem perature range, supply voltage change, s hock and

vibration and aging (20 years).

4) Specifications at time of shipm ent after 48 hours of operation.

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

frequency, measured after 30 minutes of continuous operation at a stab le 25°C.
