Averaging method
The exponential averaging method used
achieves at least 95% of the measured value
after the set averaging time.
Min. and max. values
The device measures and calculates all
measured values in all 10/12 periods. Min. and
max. values are determined for most measured
values.
The min. value is the smallest measured value
that has been determined since the last deletion.
The max. value is the largest measured value
that has been determined since the last deletion.
All min. and max. values are compared with the
associated measured values and are overwritten
if fallen below or exceeded.
The device saves min. and max. values every
5 minutes in an EEPROM without the date and
time. Therefore, in the event of a supply voltage
failure, only the min. and max. values from the
last 5 minutes can be lost.
12.7.4 Deleting min. and max. values
(parameter address 506)
If you configure the parameter address 506 with
“001”, all min. and max. values in the device are
simultaneously deleted.
The max. value for the current mean value is an
exception. The max. value for the current mean
value can also be deleted directly in the display
menu by pressing and holding key 2.
12.7.5 Measured value display, automatic
display change and changeover time
(parameter address 037, 038, 039)
For a detailed description, see chap.
„14. Measured value display and automatic
display change profile“ on page 44.
12.7.6 User password
(parameter address 050)
In order to protect already programmed or
configured data, the device offers password
protection. In the standard setting, the device
does not have password protection.
Activating password protection:
In the parameter address 050, assign a password
(settings 001-999).
Deactivating password protection:
Configure parameter address 050 with the
setting 000.
Password entry with activated password
protection:
·The password menu with the display “000”
appears and you will only get into programming
mode after entering the user password.
·The first number of the user password (the first
“0”) flashes.
·Using key 2, configure the desired first number.
·Using key 1, switch to the 2nd number.
·Configure the correct number combination for
your user password correspondingly.
·After successful entry, you will arrive into
programming mode for the current transformer.
