The model 2501A will also accept inputs up to 10mA but it’s maximum input voltage is 2400 volts. The gain stages are set for inputs of 2400, 1200, 600, 480, 360, 240 and 120 volts.
Both models are front panel and IEEE488 controllable. The two LCD displays monitor the null and output of the divider. The divider is housed in a rack mounted enclosure and is fully protected against transients. All connections are made to the rear of the instrument.
The model 2501A compares the current through the high voltage capacitor to a low voltage standard capacitor connected to the feed-back circuit of the current comparator. The current comparator automatically corrects for any phase and magnitude errors. The divider output is determined solely by the capacitance ratio of the two standard capacitors. Recommended calibration for the 2501A is 3 to 5 years.
