Power Quality Logger

Using the Logger

Connect the Logger as follows:

Note

∆(Delta) or Υ (Wye) measurements

The 1744/1743 Logger is prepared for logging in 3-phase 4-wire (Wye) systems (P-N), or 3-phase 3-wire (Delta) systems (P-P). Please note the different types of connection and configuration in the PQ Log software.

1.Connect all required measuring leads.

2.If you want to supply the Logger from an extra outlet, use the supplied line power adapter. The power supply leads can also be connected in parallel to the voltage test leads, but the voltage is limited to 660 V RMS ac.

3.Connect the current clamp set or Flexi Set to the Logger.

4.Connect the current sensor to the conductor under test.

5.Connect the dolphin clips to the test leads. For 3-phase, 4-wire systems, connect the N-test lead first, and then the other phases.
