PURPOSE:To eliminate the need for a position adjustment mechanism for positioning a receiver accurately by providing a path loss correction value storage section outputting a frequency and plural loss correction values for each measuring path stored in advance to a control section. CONSTITUTION:A main control section 1 measures the sensitivity of a selective call radio receiver 9 and when the measured value of all receivers 9 is obtained the frequency at that time is outputted to a path loss correction storage section 4. The path loss correction value storage section 4 outputs plural loss correction values (c) for each measuring path and a frequency stored in advance upon the receipt of the frequency and the main control section 1 receives the path loss correction values (c) to correct the sensitivity measured values of each receiver 9 and outputs the result as the sensitivity measurement externally. Thus, the device positioning accurately the receiver 9 is not required an the adjustment of position every time the frequency of the receiver 9 changes is not required. |
