Product Review

The i30s current clamp is based on hall effect technology for use in measurement of both DC and AC current. The i30s may be used in conjunction with oscilloscopes and other suitable recording instruments for accurate non-intrusive current measurement. Specified current range: 30 mA to 30A DC, 30 mA to 20 A AC rms. Usable current range: 5 mA to 30 A DC, 30 mA to 20 A AC rms. Crest factor: 1.4". Output sensitivity: 100 mV/A. Accuracy (at +25 degree C): +/-1 percent of reading +/-2 mA. Resolution: +/-1 mA. Load impedance: greater than 100 kilo ohm. Conductor position sensitivity: +/-1 percent relative to center reading. Frequency range: DC to 100 kHz (- 0.5 dB). Phase shift below 1 kHz: less than 2 degrees. Temperature coefficient: +/-0.01 percent of reading/degree C. Power supply: 9 V Alkaline, MN1604/PP3, 30 hours, low battery indicator. Working voltage (see Safety Standards section): 300 V AC rms or DC. Maximum conductor size: 19mm diameter. Output connection: Safety BNC connector, supplied with safety 4mm adapter. Output zero: Manual adjust via thumbwheel. Cable length: 2 meters. Operating temperature range: 0 to +50 degree C. Storage temperature range (with battery removed): -20 to +85 degree C. Operating humidity: 15 to 85 percent (non-condensing). Safety standards: BS EN 61010-1: 2001, BS EN 61010-2-032: 2002, BS EN 61010-031: 2002, 300 Vrms, Category III, Pollution Degree 2, Use of the probe on uninsulated conductors is limited to 300 V AC RMS or dc and frequencies below 1 kHz. EMC Standards: EN 61326: 1998 +A1, A2, and A3. Measures 71mm width by 183mm height by 25mm depth.
