IM DL850E-01EN
Storing and Recalling Setup Data (Setup Data Store and Recall)
You can save up to 16 sets of setup data to specific internal memory areas. It is convenient to save setup data
that you use frequently. You can save a set of setup data to one of the following numbers.
1 to 16
By specifying these numbers, you can store and recall setup data easily.
You can attach comments in the same way that you can when you save waveform data.
Calibration (CAL)
Executing Calibration (Execute Calibration)
Calibrates following items. Execute calibration when you want to make accurate measurements.
• Vertical-axis ground level
Calibration is performed automatically when the power switch is turned on.
Notes about Calibration
• Allow the DL850E/DL850EV 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 a stable temperature environment 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 DL850E/DL850EV.
Auto Calibration (Auto Calibration)
Auto calibration is executed when you start signal acquisition if any of the time periods listed below has elapsed
since the power was turned on.
• Approx. 3 minutes
• Approx. 10 minutes
• Approx. 30 minutes and every 30 minutes thereafter
Power Integration Calibration (On Models with the /G5 Option)
Executing Calibration (Execute Calibration)
Calibrates the following items. Execute calibration when you want to make accurate measurements.
• Ground Level of Power Analysis Items
This calibration is not performed automatically.
To make accurate power measurements, perform this calibration manually.

Snapshot (SNAPSHOT)
Retains the currently displayed waveforms on the screen. This feature allows you to update the display without
having to stop waveform acquisition. It is a useful feature when you want to compare waveforms.
Snapshot waveforms are displayed in white.
You cannot perform the following operations on snapshot waveforms.
Cursor measurement, automated measurement of waveform parameters, zoom, or computation
You can save and load snapshot waveforms.
