The Real Diving Emissions (RDE) regulation has been introduced since September, 2017 by utilizing the Portable Emissions Measurement System (PEMS). For the PEMS for the solid Particle Number (PN) measurement (PN-PEMS), the validation tests are required by comparing to the stationary PN measurement system on a chassis dynamometer prior to the on-road emissions testing. However, there are some cases that the emission results of PN-PEMS have big difference for that of the PMP system as the PN-PEMS does not have the same system configuration and calibration procedures as a PMP system. In this paper, the influence of the calibration procedure to the PN emissions results was observed by applying the calibration procedure of the PN-PEMS to the PMP system. The current systems configurations for PMP system and PN-PEMS, and the differences of them were described. And, the calibration procedure of the PN-PEMS was applied to the PMP system to adjust the system detection efficiency at 23 nm. Finally, the influence of the calibration protocol was investigated by compared the PN emissions of PMP system and the on PN-PEMS.
