  • Page 17: Installation

    Installation Installation Chroma 51101-1 Thermal/Multi-function Data Logger (It is called eLogger for short. The manual adopts this name for instructing and reading conveniently.) is an efficient instrument for measuring temperature, DC voltage and DC current which equipped with compact size and carry convenience.
  • Page 18 Figure 1-2 Use eLogger single point measurement structure Figure 1-3 Use eLogger multiple points (coordinate with Chroma_eLV program, 4 points at most) measurement structure The similar products on the market, only Chroma eLogger product can CAUTION contact the measured device with high voltage directly, still keep accurate and reliable measurement result due to high voltage isolation protection circuit inside it.

  • Page 19: Temperature, Voltage And Current Measurement

    Installation Figure 1-4 Only Chroma eLogger is with high voltage isolation protection circuit. It can get safety accuracy measured function under high external voltage environment. Temperature, Voltage and Current Measurement Chroma 51101-8 is for measuring temperature and DC voltage, among them temperature measurement use various thermocouples of mini type connector which includes ITS-90 standard defined thermocouple of B, E, J, K, N, R, S or T type as Figure 1-5 shown.

  • Page 21: Program Operation

    Program Operation Program Operation Installing Program Chroma 51101-1 eLogger is a measurement instrument via computer connection operation and gets measurement result via computer operation interface. Therefore, one eLogger measurement program (Chroma eLogger Viewer program, Chroma_eLV) will be attached to eLogger. Please be sure the computer using Microsoft Windows operating system, insert CD with the good and CD content will be executed automatically as Figure 2-1 shown.

  • Page 22: Executing Program

    Thermal/Multi-function Data Logger 51101-1 User’s Manual Executing Program Before executing the program, please connect eLogger to idle USB port of computer firstly and then start Chroma_eLV program. First of all, the program main screen will be appeared as Figure 2-2. The program can support 4 eLoggers’ measurement at most and difference calculation of 2 among them.
  • Page 23 Program Operation Figure 2-3 Data display (a) before completing communication setup and (b) after completing communication setup When using several eLoggers foe measuring, COM ports of each eLogger are different. There is no fixed location relationship between COM port and USB port, it is difficult to infer the program displayed eL1~eL4 to correspond to which location of actual USB port.

  • Page 24: Data Display

    Thermal/Multi-function Data Logger 51101-1 User’s Manual Data Display In each data display area, there are various settings except for data display as Figure 2-5 shown. Figure 2-5 Various settings of data display area COM Port Selection: The details of COM Port selection are described in 2.3.
  • Page 25 English letter. The measurement of voltage/current need to use Chroma dedicated VA-480/IA-3 Note adapter. It is only for measuring DC voltage/current but can’t measure AC voltage/current.
  • Page 26 Thermal/Multi-function Data Logger 51101-1 User’s Manual location may be not the location that users desire to measure temperature point as Figure 2-8 (a) shown. Thus, thermocouple read temperature (T_TC) and measurement point temperature (T_sample) to be gotten will have difference. For reducing this difference as possible, users can test temperature difference between these two points (T_sample-T_TC=Offset) i.e.
