11.1.1 CT Test Probe Setup
Functionality:
Verifies connected probes if a problem occurs
Description:
When entering this screen, the PowerMaster
®
performs both a “Probe Scan” (see Section 13.8.2)
and allows the user to verify probe connections. A key is displayed at the left of the screen and
shows what probes are active and required for this test. Color codes are also displayed (A = red,
B = yellow, C = blue, N = gray).
If the primary probe(s) are not connected at this point, an error is displayed. The signal next to
the Primary Current fields (PIa, PIb, PIc) displays red. To rescan the probe inputs, press F1. If
the probes are detected, a green signal displays next to the primary probe fields
A single primary probe (Flexible current probe, Amp Litewire, or clamp-on probe) is required. The
user has the option to connect up to three (3) primary probes for three-phase testing. These
probes will connect to the 3-Phase Probe Adapter Cable. This cable is then connected to the
PROBE SET 1 or PROBE SET 2 input on the front panel.
