14-6. Bar Meter Auto Adjustment (Barmeter Auto Adjustment)
Because this unit has a high input impedance, when the input format is set to Single-ended, the bar meter
may perform offset recording when the BNC connector is open. Continued usage will not affect the
measurement data or its accuracy, but the offset can be canceled by executing the bar meter auto adjustment.
When executing, set the input format single-ended with the measuring unit front panel S/D selector switch,
and then set the input BNC connector to open.
