Comparing the results of FG5/240 absolute gravimeter with the average of the four times observations by FG5/112 at the same site in Jixian station, the mutual difference is 0.15×10-8 ms-2. It is proved that FG5/240 has the good performance of the instrument after repair, and the measurement task can be performed. Source
