General Programming Description
All programming is performed using the ENTER button. To set up a function
there are sequential steps that have to be performed. As each step progresses,
either a single digit or the entire display will flash. The flashing digit, or flashing
display, will be looking for acknowledgement if it is the desired digit or display.
Pressing the ENTER button will accept the value. If the flashing display or digit is
not the one desired, wait and the value will change.
Each digit will flash for 3 seconds before it starts to change, when it is accepted
the next digit will flash for 3 seconds. This procedure will continue until the
ENTER button is pressed while the desired option is flashing. As the
programming progresses there will be times when a decision has to be made, an
example is yes or no ( y or n ).
ENTER and ACK Functionality
The ENTER button is used to program the meter for various functions.
The ACK button is used to acknowledge the relays during operation and to quit
main menu scroll during programming, diagnostic menu, and calibration.
