CT3683 Cal Test

CT3681/CT3683 Datasheet High Voltage Di erential Probe 70 MHz / 7 kV Overview: Differential probes allow safe, accurate measurement between two voltage points where neither point is referenced to ground. The CT3681 and CT3683 both offer a 70 MHz bandwidth and can test up to 7 kV (DC + AC peak). Compatible with oscilloscopes from all major manufacturers, the probes can be battery operated, powered by a universal adapter (optional), or powered by USB power lead (optional) if the oscilloscope is so equipped. Features: Meets IEC 61010-031 safety standard 70 MHz bandwidth (-3 dB) Up to 7 kV differential and common mode voltage Selectable attenuation settings of 100x/1000x Compatible with most oscilloscopes Power and over-range indicators High accuracy (2%) High CMRR Unique high voltage input leads and hook probes (CT3683) Powered by 4 AA batteries (included) Power adapter, CT3723 (optional) USB power lead, CT4122 (optional) CT3681 shown Technical data subject to change.
