7.1. Password Protection
7. Programming
The following sections comprise step by step procedures for configuring the DC energy meter according to user
requirements. To access the set-up screens press and hold key for 2 second. This will take the user into the password
input screen (Section 7.1).
Password protection can be enabled to prevent
unauthorised access to setup screens.
By default password protection is disabled.
To enable password protection the user need to set a
password other than 0000.
Enter Password, prompt for first digit. The symbol * at
the first digit denotes that the decimal Point will be
flashing. In special case where the Password is “0000”
pressing the key when prompted for the first digit will
advance to “Password confirmed” screen.
Use & keys to increase or decrease the value of
the digit. The value can go from 0 to 9 and will wrap
around. After reaching the desired digit on display,
press key to confirm and go to the next digit. The
decimal point next to the 2nd digit will start flashing.
Following the same steps as above enter all four digits.
Pressing enter key after the last digit will take the user
to password confirmation screen.
Now when the user presses key, there are two
possibilities for the next screen.
1) If the entered password is correct the display will show
the password.
Note: The flashing decimal point indicates the cursor
position, a steady decimal point will be present to
identify the scaling of the number until the cursor
position coincides with steady decimal point
position. At this stage the decimal point will flash.
