Current Probe (AC/DC) - 1

current Probe (AC/DC) Technical Specifications Doble’s Current Probe (Part number 401-0055) is a tool that aids in the measurement of current signals when using the Recording feature of Doble’s Transwin program. This probe converts the current in the conductor that it encircles into an equivalent voltage signal. This equivalent voltage signal when applied to the logic input of the F6150 instrument gets translated into appropriate amperes by the Transwin program. Electrical Specifications Operating Range: 0.2 to 200 A Measurement Range: 20 A Range: 0.2 to 20 A rms or DC 200 A Range: 0.5 to 200 A rms or DC Noise 20 A Range: DC to 1 kHz: ≤ 80 mV or 0.8 A (peak to peak) DC to 5 kHz: ≤ 120 mV or 1.2 A (peak to peak) 0.1 Hz to 5 kHz: ≤ 20 mV or 0.2 A (peak to peak) Output Signal: 100 mV/A on 20 A range 10 mV/A on 200 A range Accuracy and Phase Shift*: 20 A Range: 0.5 to 20 A: 1.5% reading ± 0.5 A Phase shift: 45 to 65 Hz; 10 to 200 A: ≤ 3.5º 200 A Range: 0.5 to 100 A: 1.5% reading ± 1 A 100 to 200 A: 2.0% reading Phase shift: 45 to 65 Hz; 10 to 200 A: ≤ 2.5º *Refernce conditions: 18º to 28ºC, 20 to 75% RH, external magnetic field < 40 A/m, no DC component, no external current caryying conductor, test sample centered, 1MΩ ≤ 100pF load, zero adjustment prior to measurement [DC only] DC to 65 Hz, battery voltage 9 V ± 0.1 V Overload: 200 A Range: DC to 1 kHz: ≤ 10 mV or 1 A (peak to peak) DC to 5 kHz: ≤ 15 mV or 1.5 A (peak to peak) 0.1 Hz to 5 kHz: ≤ 5 mV or 0.5 A (peak to peak) Load Impedance: > 1 MΩ/100 pF Insertion Impedance: 0.39 Ω @ 50 Hz, 58 Ω @ 1000 Hz Working Voltage: 600 V rms. Common Mode Voltage: 30 V rms. Influence of Adjacent Conductor: < 10 mA/A at 50 Hz at 23 mm from the probe Influence of Conductor Position in the Jaw: 0.5% reading (DC to 440Hz) Battery: 9 V alkaline (NEDA 1604A, IEC 6LR61) Low Battery: Green LED on when battery voltage ≥ 6.5V Battery Life: Approx. 50 hours with alkaline battery Overload Indication: None Auto Off: 10 minutes (may be disabled at power-up by pressing Zero button on; green LED blinks three times to indicate auto-off is disabled)
