*spec refers to the quoted frequency response value, e.g., for a “30 s” sensor, the value of spec would be 30 s = 0.033 Hz.

**Temperatures below –20 °C may be accommodated with additional care. Please consult Güralp Systems for advice.

†Because centring, locking, and unlocking consume varying amounts of power, it is recommended that you use a power supply capable of delivering 1 A at 12 V.
