An oven-stabilized zener diode internal reference provides an overall output accuracy of ±500 µV and ±25 ppm of the setting with zero drift of ±5 µV/°C and full-scale drift of 4 ppm/°C max.
Output is set by unique front-panel lever switches which provide rapid, positive contact adjustment.
Voltage outputs may be continuously varied within ±1.5 millivolts of selected readings by using a front
panel vernier control.
The DVC-8500 output is available from both front panel banana jacks and rear panel 36-pin gold-plated
PC connector fitted with lug terminals. DVC-8500 offers transformer isolation up to ±300V dc.
Output line rejection is within ±50 microvolts of zero.
The black-anodized extruded aluminum housing provides excellent shielding from electrical noise.
