Step 2B - For instruments with software revision r3.00 and above
Upon power up, a brief flash on all displays (upper and, if equipped, lower) will occur to show
the instrument is "alive". Then 7XXX will be displayed (X representing digits) then XXXX, then
XXXX, identifying the twelve digit model number as defined in the order matrix. Next, the
EPROM part number will be indicated P-XX. After the EPROM part number, the software
revision level will be displayed in the format rX.XX followed by P.dn (if Pen Action on Power
Up, PAPU, in Program Mode is set to 0, pens go to "home" position at power up). During this
display, the decimal point after the "P" will blink to show the mode is active. Upon successful
completion of this routine, oPEr or oFF will be displayed for about 3 seconds. The mode
displayed will be mode that the instrument was in when the power was turned off. During this
time the operator may select another mode (Alarm Set, Enable) or non-operational mode
(Test, Program, Cal).
