DC Zero
DC Zeros is a quick, automatic process that corrects offset errors. Offset errors
increase with time on several output ranges. If a 5725A Amplifier is attached, it
also zeros the 11 A dc range. This process takes approximately 2 ½ minutes
(plus an additional 30 seconds for the 5725A).
Run DC Zeros
To execute dc zeros, from the normal operation screen:
1. Touch Setup Menu to show the Setup Menu. See the Setup Menu section of
Chapter 4 of the Operators Manual.
2. Touch the Calibration menu.
3. Touch Run DC Zero to start the dc zeros routine. The status of the dc zero
calibration is shown as the Product progresses through a series of steps.
When completed, the Product shows “Calibration complete”.
Note
If the Product is not warmed up, the display prompts to continue or
cancel the DC Zeros function.
4. Touch Close to proceed with Product use.
DC Zeros Reminder
Specifications require that dc zeros be run at least every 30 days. If 30 days
passes and dc zeros is not done, the display prompts to run the process.
To override the message and run dc zeros at a more convenient time, touch
Cancel. To run dc zero at this time, touch OK.
Note
If this message shows after powering on the Product, let the Product
warm up before running dc zeros. Otherwise an error message
indicates that the Product is not warmed up. To ensure the best
performance, complete the warmup.
