20. PQube will record all events but will only store waveform and RMS data for the first event This is because your PQube is still clearing the space that it requires to record the information It is important to note that as long as your PQube is running it is almost impossible for it to miss an event your PQube can miss an event if more than 4 events of any one type occur within 4 seconds of each other During an event your PQube will always be sampling the voltage at 256 samples per cycle You can change the number of samples per cycle written to an event recording 256 128 64 or 32 samples per cycle by changing the Recorded_Samples_Per_Cycle setting in the Setup ini file on your SD card Why would I want fewer samples per cycle in my recordings Your PQube Records 1024 samples at the beginning of an event and 1024 samples at the end of an event If your PQube is configured to record at 256 samples per cycle it will record 4 cycles at the beginning and 4 cycles at the end of the event 1024 256 4 If you set the recording rate lower you get a longer recording with fewer points per cycle For example if you choose 64 samples per cycle your PQube will continue to sample at 256 samples per cycle but the output recording will be written at 64 samples per cycle Your Event recordings will have 16 cycles at the beginning and 16 cycles at the end of the event 1024 64 16 Of course you always get many cycles of RMS values 10 seconds o

L1 current sensor to the same conductor This is important for correct power and energy calculations There are three main types of current module the XCT4 with current inputs the XCT5 with voltage inputs and the CT4 You only need one current module to measure current power and energy Pick the version that works best for you XCT4 Current Module Current inputs You can connect external current transformers to your PQube There are two versions of the XCT4 module each will work with a different type of CT Make sure you carefully read all safety information provided by the manufacturer before installing CTs If you are using a CT with a current secondary you can use the XCT4 1A 00 or the XCT4 5A 00 which have 1 and 5 Amp inputs respectively Your PQube places almost zero burden on the current transformer less than 0 1 VA so you can select almost any current transformer XCT5 Current Module Voltage inputs If you are using a current sensor that has a voltage output you can choose between the XCT5 0 333V 00 XCT5 01V 00 XCT5 05V 00 and XCT5 10V 00 which have 0 333 1 5 and 10 Volt inputs respectively You can use either standard current transformers or split core current transformers Standard current transformers are generally less expensive and are often more accurate Split core transformers are much easier to install In general the accuracy of your PQube s current measurements are so precise roughly 0
