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 do the dc zero calibration every 30 days.
In addition, do the dc zero calibration after powering up the Product for the first
time after unpacking following a shipment or if it is exposed to an environmental
change of greater than 5 °C. An automatic prompt will be shown to run the DC
Zero calibration 30 days after the last zero was performed.
To execute zeros calibration, from the power-up state:
The DC Zero function is affected by the calibration security state.
1. Push the Setup Menu>Calibration softkeys followed by the Run Zero Cal
softkey. The display shows the progress of zero calibration with the name of
each part of the procedure. The numbers at the right side (for example,
"8/19") give an indicator of the percentage of completion. In a short time,
zeros calibration is finished. The display indicates when the calibration
procedure is complete.
2. To resume normal operation, touch OK and Exit.
