The following table gives a summary of the button operations
in programming mode.
Button Press Operations
SCROLL Short press Scroll through a menu item list in a
highlighted window or increment a
highlighted digit in a numeric field
SELECT/ENTER Short press (less than
1 second) = SELECT
Highlight a menu window or a digit in a
numeric field
SELECT/ENTER Long press (1 to 2
seconds) = ENTER
Store the changed item or perform an
action indicated in a highlighted window
Entering Numeric Values
Whenever a numeric value is to be changed, use a short
press on the SELECT/ENTER button to highlight a desired
digit, and then use the SCROLL button to change the value of
the highlighted digit. A highlighted digit appears in inversed
color. If you missed a digit, just continue moving through the
rest of digits until you reach the desired place.
Once the number is set to the desired value, press and hold
the SELECT/ENTER button for 1-2 seconds to save your new
setting.
To reject your changes and restore the previous value, use a
short press on the SELECT/ENTER button to return to the
higher-level window.
Password Security
The setup menus are secured by 8-digit user passwords.
Every time you enter programming mode, you are prompted
for a correct password. The meter is primarily shipped with
all passwords preset to 9 at the factory. See Meter Security
in
Chapter 2 for more information on the meter security levels.
It is recommended that you change the factory set passwords
as fast as possible to protect your setups and accumulated
data from unauthorized changes. See Configuring Meter
Passwords in Chapter 5 on how to change passwords in your
meter.
Enter the password as you enter numeric values. As you
move to the next place, the digit entered is saved and then
zeroed. If you missed a digit, you should re-type all
preceding digits before you reach the missed place again.
