Notes about Calibration
Allow the DL850/DL850V to warm up for at least 30 minutes before you execute calibration. If you
execute calibration immediately after power-on, the calibrated values may drift due to temperature
changes or other environmental changes.
Execute calibration in an environment with a stable temperatu
re ranging from 5 to 40°C (23 ± 5°C
recommended).
Do not apply signals when calibrating. Calibration may not be
executed properly when input signals
are being applied to the DL850/DL850V.
Auto Calibration (Auto Cal)
Auto calibration is executed when you start signal acquisition if you have changed Time/div and any of
the time periods listed below has elapsed since the power was turned on.

One hour and every hour thereafter
If calibration is executed while signals are being applied to the DL850/DL850V, we recommend that
you recalibrate the DL850/DL850V without any signals being applied to it.
