d&b audiotechnik D12 - Calibrate

Definition of values:
Min
Lower limit of the impedance window witch is by default set to –20 %.
Max
Upper limit of the impedance window witch is by default set to +30 %.
Calibration
The impedance reference values derived by the calibration.
Last Mon
Impedances detected by the last measurement.
Last Check
Impedances detected by the last System Check (see also section System
Check on page 14).
Last Error
Last determined impedance values that led to an impedance error.
These values will be kept even after acknowledgment of the error
message. They will only be overwritten when another error occures. A
calibration will reset them to 0.
Pilot Freq.
Test frequency of the pilot signal for the respective driver.
Pilot Level
Reference level of the pilot signal derived during the calibration
procedure.
Threshold
Large signal threshold. If the output signal exceeds this voltage level
during the measurement the tolerance limits for this particular
measurement are increased in order to compensate for the reduced
accuracy.
Calibrate
NOTICE:
Ensure that all components of the system are wired and working
correctly before executing the calibration!
Selecting "Calibrate Now" enters the sub-menu "Calib. Load
Monitoring" and as a precautionary measure the following message
will be given:
Calib. Load Monitoring
Cancel
A
Calibrate
Calibration interrupts
your audio program!
Selecting "Calibrate" starts the calibration procedure while the progress
of the procedure is displayed. It can be cancelled/interrupted and
restarted at any time by pushing the encoder during the procedure.
After a successful calibration the reference values will be displayed and
"Ok" will appear in the bottom line of the calibration screen.
Confirm to get back to the Load Monitoring menu.
If the calibration was not successful a respective error message will be
displayed. Also refer to section 2.5.2 on page .
