Sigma intelligent hand-held Terminal (IHT)
Housed in a robust, industrial polycarbonate and polyamide enclosure with IP65 protection, membrane keyboard and back-lit graphic LCD, the IHT allows remote working whilst still having live display information showing all the main electrical parameters and data capture.
The displays are designed to simplify the testing, setup and adjustment of the supply-on-test for the operator.
When carrying out full load testing one page shows all the true RMS three-phase measurements of voltage (V), frequency (Hz), current (A), power (both kW and kVA) and power factor (Cos Ø).
For transient-response testing, the voltage and frequency of the last load change are captured and displayed on the dynamic graph including maximum and minimum data. The status line includes the elapsed time since the last load was applied.
