4-5. Calibrating DC Zeros
DC zeros is a quick, automatic process that removes dc offset errors on all ranges and
optimizes internal settling parameters to improve measurement speed. Specifications
require that you execute dc zeros at least as often as every 30 days. To execute zeros
calibration, proceed as follows from the power-up state:
Note
The position of the rear panel CALIBRATION switches does not matter for
dc zeros calibration.
1. Press the [UTIL MENUS] key followed by the "Cal" and "Zero Cal" softkeys. The
Control Display shows the progress of zero calibration with the name of each part of
the procedure. The numbers at the right side (e.g., "8/19") give an indicator of the
percentage of completion. In a short time, zeros calibration is finished. The display
changes to:
add0b.eps
2. To resume normal operation, press the "Back to Prev Menu," "Done With Cal," and
"DONE With Utils" softkeys (they are all the same key).
