Abstract Earth tide，earth’s free oscillation and teleseismic surface wave are common signals with different frequency in premonitory data.The perormance in high frequency of DSQ tiltmeter，vs1 vertical pendulum tiltermeter and SQ2I horizontal pendulum tiltermeter at the samesite were compared.The results prove that the perormance in lowfrequency of Earth tide，earth’s free oscillation are consistent，the perormance of teleseismic surface wave are different from each others.The difference of the three tiltermeters’ response might be caused by the difference of perormance in high frequency of the instruments and different length of the base line.
