Always check that the arrow of the current sensor points towards the load. This ensures that the phase angle will be correct for
power measurements and other measurements that depend on the phase.
However, when a recording session has ended and been uploaded to a PC, it is possible to change the direction of the current (I1,
I2, or I3) using the PEL Transfer software. This makes it possible to correct the power calculations.
4.1.1. SINGLE-PHASE, 2-WIRE: 1P-2W
Source
Load
For Single-Phase 2-Wire measurements:
Connect the N test lead to the neutral conductor
Connect the V1 test lead to the L1 phase conductor
Connect the I1 current probe to the L1 phase conductor.
Check that the current arrow on the sensor points towards the load.
This ensures proper phase angle for Power Measurements and other
phase-sensitive measurements.

DUAL-PHASE (SINGLE-PHASE 3-WIRE FROM A CENTER TAP TRANSFORMER): 1P-3W
For Single-Phase 3-Wire (Split Phase) measurements:
Connect the N test lead to the Neutral conductor
Connect the V1 test lead to the L1 phase conductor
Connect the V2 test lead to the L2 phase conductor
Connect the I1 current probe to the L1 phase conductor.
Connect the I2 current probe to the L2 phase conductor
Check that the current arrow on the sensor points towards the load.
This ensures proper phase angle for Power Measurements and other
phase-sensitive measurements.

4. USE
When the instrument has been configured, you can use it.
4.1. DISTRIBUTION NETWORKS AND CONNECTIONS OF THE PEL
Start by connecting the current sensors and the voltage measurement leads to your installation according to the type of distribution
network. The PEL must be configured (see § 3.4) for the distribution network selected.
