The calibrator features high performance for such a small, low-cost instrument. An active buffered output amplifier provides very low output impedance and up to 25 milliamps output current.
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 rear connector has sense feedback inputs to reduce errors caused by cable resistance. A front-panel LED overload lamp lights if the output exceeds 25 mA and current limiting occurs at 70 mA output. The output circuit accepts up to 25 mA source or sink current at rated accuracy. Output line rejection is within 50 microvolts of zero.
