Ammeters for Constant Current Series Circuits
Constant current regulators (CCRs) produce non-sinusoidal waveforms. Traditional ammeters reading the average current will produce inaccurately low values on airfield lighting circuits. Calibrating equipment based upon these incorrect readings may dramatically reduce the lamp life for airfield lighting and adversely affect equipment performance.
For constant current airfield lighting circuits, only a true-rms meter with current clamp accessory must be used to accurately indicate the current present. Such meters include selected models manufactured by:
- Beckman Industrial
- Fluke
- Simpson
- B&K Precision
- Circuitmate
