4-4. DC Zeros
DC zeros is a quick, automatic process that removes any offset error on the 11V and 2.2V
ranges, and removes offset and gain errors on the 220 mV range. If a 5725A Amplifier is
attached, it also zeros the 11A dc range. This process takes about 2.5 minutes (plus an
additional 30 seconds for the 5725A).
4-5. Executing DC Zeros
To execute dc zeros, proceed as follows from the power-up state:
1. Press the following sequence of softkeys:
“Setup Menus”→“Cal” →“Zero”
2. When the process is finished, a message appears that tells you to press any key to
continue. Press any key to exit the dc zeros display.
3. To return to normal operation, press P twice.
4-6. DC Zeros Reminder
Specifications require that dc zeros be executed at least every 30 days. If the 30-day time
period elapses and dc zeros is not performed, the following message appears on the
display when the calibrator is powered on, or reset.

MENU
To override the message and perform dc zeros at a more convenient time, press the
softkey under ZERO LATER (the softkey next to P). To perform dc zero at this time,
press one of the softkeys under ZERO NOW.
Note
If you receive this message after powering on the calibrator, allow the
calibrator to warm up before executing dc zeros. Otherwise an error
message appears indicating that the calibrator is not warmed up. To ensure
the best performance, the warmup period should be completed.
