PROBLEM TO BE SOLVED: To easily perform the instrumental error correction work of a measuring instrument and to enhance security properties. SOLUTION: An instrumental error adjusting device 10 is constituted of the control substrate 14 mounted in a filling device 12, a sealing switch 16, a display device 18, and a remote controller 20 for inputting an instrumental error correction value from the outside by infrared rays. The control substrate 14 is provided with a control circuit 22 performing the measuring operation of a flow rate, a memory 24 and a remote control receiving circuit 26 for receiving the operation signal transmitted from the remote controller 20. The control circuit 22 is equipped with a temperature correcting arithmetic processing part 28, an instrumental error correcting arithmetic processing part 30, and a remote control processing part 32. The remote control processing part 32 registers an instrumental error correction value to an instrumental error correction factor data memory 44, only in such a case that the sealing switch 16 is turned off when the operation signal (instrumental error correction value) transmitted from the remote controller is received by the remote control receiving circuit 26.
