Страница: 19 / 79

Calibration menu contains internal calibration constants and other tools for device adjustment and is
therefore password protected. See chapter 6 for more details on 9010+ adjustment. Calibration menu
has following items:
1. Data. Contains current calibration data. Structure of this menu is described in chapter 6.1.
2. Backup. Calibration data backup. See below for more details.
3. Password. Changes calibration password. Calibration password gives access to Calibration
menu and Date/Time settings in Information menu.
4. Calibration date. Calibration date is updated automatically upon calibration data adjustment or
just by manual confirmation (if calibration doesn‘t require adjustment).
5. Calibration interval. Recommended interval is 12 months.
Backup function allows you to save and recall entire sets of calibration data. Calibration data are also
saved automatically when any calibration value gets changed, creating a record with “Auto” storage (or
overwriting an existing one if the last change occurred within last 90 days). Use softkeys to save and
recall previously stored calibration data sets:
1. Back up. Saves currently used calibration data, overwriting existing record on selected Location.
Only empty records and records with Calibration access and Manual storage can be overwritten.
2. Try. Loads selected record temporarily, original calibration data will be restored on next
calibrator startup.
3. Load. Loads selected record permanently.
4. Delete. Deletes record. Only records with Calibration access and Manual storage can be deleted.
Preset feature allows you to save and recall one of up to 100 calibrator configurations so that you can
get to work quickly instead of setting up the calibrator every single time. Push PRESET button to show
list of saved presets:
To recall a predefined configuration, select its preset from the list and push Load softkey. Configuration
will be loaded with output turned off for safety reasons.
Similarly you can save a configuration by choosing Location 0 – 99 from the list and pushing Save
softkey. Preset includes configuration of:
- Function and mode (for example AC Power)
- Main value (for example 10 VA)
-
Auxiliary parameters (for example 50 Hz, 10 V, 1 A, 0 °)
- Additional Device/Setup menu parameters of current Source and Meter function
While editing functions, parameters are stored in temporary RAM until another preset is selected or the
device is restarted. Preset doesn’t include harmonic distortion parameters nor main menu settings except
those mentioned above. For harmonic preset feature see chapter 4.1.3.
