EDC 501 J

PROGRAMMABLE DC VOLTAGE STANDARD -13V to +13V
Option J = Bipolar Operation

Power ON : OK
Tested : OK - Calibration OK
Only a few values that are a little tight in precision

EDC 501 J is a multi-range, high accuracy DC voltage source and calibrator for use in applications up to 10 Volts DC.
    1.1.3 Accuracy:
    ±(0.002% of programmed value + 0.0005% or range +3μV). The accuracy is
    based on the "Limit of Error" (or "Worst Case" Method. All other specifications
    noted hereafter, which effect accuracy, e.g., line, load, temperature, and drift are
    included in the accuracy statement. Thus, all other specifications listed are (*)
    NON-ADDITIVE.
    1.1.4 Settling Time:
    100 μs (50 μs nominal) to rated accuracy for voltage change. 10 ms (approx.)
    recovery from short-circuit.
    100 μs (max) for polarity change.
    60 ms (max) for range change.
    1.1.5 Stability (non-additive specifications)
    24 hrs: 0.001%; 90 days: ±0.0015%; 6 months: ±0.002%
    1.1.6 Ripple and Noise:
    Observe in a band pass of 0.1 Hz to 100 kHz with NO random spikes. (0.0005%
    of range +2 μV) rms.
    1.1.7 Output Current:
    10 V range: 50 mA
    100 mV range: Not Applicable. (Output voltage is within stated accuracy if load
    impedance is greater than 60 k.)
