The 6186C Current Source will source up to 100 mA in three ranges at an output voltage of up to 300 V DC. Ranges are 0 to 1 mA, 0 to 10 mA and 0 to 100 mA. Load regulation is < 25 ppm ±5 ppm of range switch setting. 4 ms or less transient recovery speed and high unit output impedance is made possible by the eliminating the output capacitor. Output programming speed is 10 ms. Two large meters, voltage and current, allow simultanious monitoring of the output state.
