NDL8000 Series

AC Voltage and Current Data Loggers

Single or three-phase, for current or voltage Data memory up to 4MBytes Recording more than one year without the need ofbattery replacement (1 minute rate) Isolated RS232 communication port Easy to use TrueGraph included Voltage Direct measurement up to 600 (750)V

AC

L-L Programmable PT ratio For single and three-phase measurement, 3 or 4 wires Simultaneuos measurement of L-N and L-L Current Inputs suitable for voltage output clamps and flexibletransducers (Rogowski) Calculation of neutral current Programmable full scale General Features Benefits

The NDL8000 series is a battery powered unit, able to record
electrical parameters. These devices replace strip chart
recorders in many applications, and they offer better
accuracy, they are lighter in weight, rugged and maintenance
free. The recorded data can be displayed on a PC.They are available for single and three-phase, 3 or 4 wiresnetworks.The 12 bit sampling and the True RMS calculation ensureaccurate measuring even by distorted vaweform.The recording start/stop can be operated by 2 keys easily.The command acknowledgment, the device status and the
battery level are indicated by two LEDS.The non volatile FLASH type memory guarantee dataretention even by exhausted battery. The standard meterconfiguration includes a 2 MBytes memory, which can be
increased to 4MBytes.The isolated RS232 allows the data logger to be connectedto a PC. By the TrueGraph software it is possible to see
instantaeous measurements, set recordings and download
recorded data.The TrueGraph software allows the graphic and tabularanalysis of recorded data. Moreover the software includes
efficient statistical and data search functions.All data can be exported to word processors for furtheranalysis or as image files. ՕՕ The models for voltage measurement can be connecteddirectly up to 600 (750)V >
AC L-L without the need forvoltage transformer. If this value is exceeded it is possible
to set the PT value. Օ The models for current measurement can also interfacedirectly Rogowski coils without the need for externalintegrators. Excellent memory capacity and long life battery ensurea long period recording without the need for data
dowloading. Օ Low cost, compactness and maintenance free are someof the advantages, in comparison with the conventional
strip chart recorders. The user programmable recording parameters make theunit suitable to a large number of applications. The
sampling rate can be selected between 1 second and 24
hours and the memorization can be chosen between
wraparound or fill-in mode. >
