cycle
All types of input are calibrated in the factory. In case a recalibration is required; it shall be carried
out by a specialized professional. In case this cycle is accidentally accessed, do not perform
alteration in its parameters. The factory calibration can be restored in the parameter rstr.
Password.
Entering the Access password. This parameter is presented
before the protected cycles. See item Protection of Configuration.
Calibration.
Enables the possibility for calibration of the indicator. When the
calibration is not enabled, the related parameters are hidden.
Input Low Calibration.
Indication of the low scale calibration signal applied to
the input.
Input High Calibration.
Indication of the full scale calibration signal applied to
the input.
Restore.
It restores the factory input calibration and the indicator factory
parameters, disregarding any modifications carried out by the user.

protection
The
DA9602
indicator provides means for protecting the parameters configurations, not allowing
modifications to the parameters values, avoiding tampering or improper manipulation. The
parameter
Protection
(
) in the Calibration level determines the protection strategy, limiting
the access to particular levels, as shown in the table below.
ProtectionLevel ProtectedLevels
1
Only the Calibration level is protected.
2
Totalization and Calibration levels are
protected.
3
Input, Totalization and Calibration levels

Levels of Protection of the configuration
ACCESS PASSWORD
The protected levels, when accessed, request the user to provide the
Access Password
for
granting permission to change the configuration of the parameters on these levels.
The prompt
precedes the parameters on the protected levels. If no password is entered, the
parameters of the protected levels can only be visualized.
The Access Password is defined by the user in the parameter
Password Change
(
), present
in the Calibration Level.
The factory default for the password code is 1111
