We present the results of a comparative measurement campaign of the beam charge carried out at SwissFEL using the following instruments: Faraday-Cup (FC), Wall-Current-Monitor (WCM), Integrating-Current-Transformer (ICT) and cavity Beam-Position-Monitor (BPM). The goal of the measurement campaign was to determine an absolute charge measurement method for a general purpose of instrument calibration and for BAG related charge measurement issues.
