Valhalla Scientific 2500EP AC/DC Current
Elgin, IL, USA
Valhalla Scientific


3 VDC/pk AC, 30 VDC/pk AC for 2500EN
Condition info:


The ranges of the Valhalla Scientific 2500EP, AC/DC Current Calibrator, are compatible with virtually all analog meters and most of the digital multimeters with AC-DC current capability. For benchtop DMMs and the handheld meters, virtually all with 10 amp measurement, the 10 amp range of the 2500EP is ideal.
Ammeters, current transformers, shunts, current sensors, coils, wattmeters and a variety of parametric tests requiring constant, yet variable, AC or DC current are but a few of calibration and lab test uses of the 2500EP.
The units fast response characteristics allow it to precisely track the input reference voltage in terms of amplitude, phase, frequency, and waveshape. Each range also features zero to 200% dynamic response capability (up to maximum output).
