AMETEK CW-P - Manual (Page 57)

Elgar CW-P Series Programming
Operation Manual 4-5
The Menu LED is used to indicate if changes have been introduced into the menu
system. If there have been no changes, the LED will light steadily. If the operator has
introduced some change to a menu variable, the LED will blink.
The Menu LED is illuminated steadily when the menu system is entered, indicating that
nothing has yet been changed. When the LED is lit steadily, the ENTER/SAVE and
ESCAPE buttons perform the same action, that being the menu system will be exited
when either one is pressed.
When the menu item to be changed is selected with the left rotary knob, use the right
rotary knob to change the specific parameter selected. When you make any change to
a menu parameter with the right knob, the MENU LED blinks, and the left knob is
locked out. Press the ENTER/SAVE button to accept and save the change; press the
ESCAPE button to cancel the change. If the parameter is returned to its present original
value with the right knob, the left knob is again enabled and the MENU LED returns to a
steady On state.
If the ESCAPE button is pressed while the Menu LED is blinking, any unsaved change
made to the menu parameter will be lost, and the CW will revert to the measurement
mode.
When using the menu system, if you stop pressing buttons or turning knobs for more
than 20 seconds, the CW will revert to measurement mode and any menu changes will
be lost.
4.3.1 Self Test
This menu item reports the outcome of the power-on self-test. If the result is PASS,
then all system operations are available. If the result is FAIL, both displays will read
FAIL nnnn. Following a self-test failure, the output relay cannot be closed and the
quantity of slaves, attached phases, and/or calibration inaccuracies can be corrected if
these were the cause of the FAIL status. You can press either the ESCAPE or the
ENTER/SAVE button to continue (without the output relay closure possible) to correct a
configuration error, if it is only configuration. If the failure is due to a non-configurable
item, the CW will need to be repaired.
STST PASS, FAIL
4.3.2 Set GPIB Port
This menu item allows the GPIB address to be set. The GPIB address will initially be
set to 25 at the factory. The range is 1 to 31.
