segment character.  Due to the limitations of a 7-segment character, some of the 
letters will be upper case and some will be lower case.  On the lower line of the 
display, the calibration data is entered.  While in Calibrate Mode, each digit is 
changed one at a time.  The digit selected to be changed will be blinking on and off.   
 
In the following operation and calibration examples, display prompts and keypad 
names will be shown in 

BOLD 

type.  The prompts will be shown in upper and lower 

case letters to illustrate approximately the way that they will appear on the display.   
 
The keypad operation is described as follows: 
 

ACCESS:   

If the 

ACCESS

 key is pressed while in the Run Mode, the MC-II 

Plus

 

Flow Analyzer will be placed in the Calibrate Mode.  Pressing the 

ACCESS

 key while the MC-II 

Plus

 Flow Analyzer is in the Calibrate 

Mode will return the instrument to the Run Mode.  When returning to 
Run Mode by pressing the 

ACCESS

 key, any data that has been input 

with the 

ENTER

 key being pressed afterward will be saved to memory.  

Any data that has been input without the 

ENTER

 key being pressed 

afterward will not be saved, and the data entered from a previous 
calibration will be retained.   

 

STEP:

   

The 

STEP

 key is primarily used in the Calibrate Mode.  Pressing the 

STEP

 key advances the digit to be changed to the left.  If the left-most 

digit is selected, pressing the 

STEP

 key again advances the digit to be 

changed to the right-most digit.  The 

STEP

 key is also used to toggle 

settings and decimal point locations.  

 

INCR:   

The 

INCR

 (increment) key is primarily used in the Calibrate Mode.  

While entering numbers, the 

INCR

 key advances the value of the digit 

to be changed by one from its initial value each time it is pressed.  If 
the 

INCR

 key is pressed when the digit is nine, the value rolls over to 

zero.  The 

INCR

 key is also used to toggle settings and decimal point 

locations.  

 

ENTER:   

The 

ENTER

 key functions only in the Calibrate Mode.  Pressing the 

ENTER

 key enters the displayed data for the current calibration 

function and advances to the next calibration function. 

 

Error Detection 

 

The  MC-II 

Plus

 Flow Analyzer will inform the operator of detected errors while in the 

Run Mode.  The 

Error

 message will be displayed to the operator in the form of the 

word 

Error

 displayed on the rate display section (lower line of the display), every 

other time that the rate is updated.  There may be from one to four errors detected at 
any one time.
