4600A - Setting Voltage Remote Sense (Optional)

If the 4600A is fitted with the REMSENSE option, this adds the capability to have Remote Sensing active on the DC Voltage Ranges (2V through 1000V Ranges, not available on 200mV Range)

To activate through the front panel/in normal operation, enter the desired voltage as normal, but instead of pressing the Volts key, press SHIFT, followed by the volts key. The unit on the display will show V4w to indicate 4 Wire/Remote sense voltage.

To disable, either reset the calibrator (Shift + C), or enter a new voltage with just the normal Volts key.

To enable remotely, send the following command

EXTSENSE ON

To disable, sense the following command

EXTSENSE OFF

To query the current state, send EXTSENSE?. The response will be "0" for off, "1" for on.

Note - the REMSENSE option corrects for loading, it does not increase the maximum available current for outputting into resistive loads
