Martel Electronics 320 - Manual (Page 19)

CLEAR KEY
The Clear key allows the operator to re-enter an
incorrect numeric entry. When the Model 320
calibrator is expecting a numeric entry, a ?????
prompt is displayed. As numeric keys are pressed, the
value is echoed on the display. If a keying error is
made, press Clr to cancel the value entered and return
to the ????? prompt.
SETUP KEY AND MENUS
The Setup key allows the user to perform certain
custom operations with the Model 320 calibrator.
When the Setup key is pressed, the display will
display two menus of items that are configurable by
the operator. Pressing the Select key will bring up a
second menu display. Pressing the Select key again
will bring back the original menus. Pressing the Enter
key will clear the Setup mode and the Model 320 will
resume its normal display.
All of the user setup parameters are retained when the
Model 320 is turned off.
