Simultaneous functions
The multifunction calibrator allows simultaneous generation of calibrated signal along with measurement of
another signal using the built-in multimeter. To use both parts of the calibrator simultaneously, cable adapters
supplied by the manufacturer are necessary.
When using the calibrator, the following states are possible; each state has its limitation, listed in the table.
Method of use
