2. Measurement of oscillating frequencies
When power is turned on, S-3530A has the internal power-on detecting circuit operating and outputs a signal
of 1 Hz from the INT1 pin to select the crystal oscillator and optimize the Cg value. Turn power on and measure
the signal with a frequency counter following the circuit configuration shown in Figure 25.
Remark If the error range is
±5 ppm in relation to 1 Hz, time shifts by about ±13 seconds a month (as
calculated using the following expression).

× 10
-6 (1 ppm) × 60 seconds × 60 minutes × 24 hours × 30 days = 13 seconds/month

Caution 1. Use a high-accuracy frequency counter (1 ppm order).
2. The 32,768 Hz signal is output uninterruptedly.
3. Determine Cg with its frequency slow/fast range property referred.
