The Zero Switch 

Pressing the ZERO switch at any time returns the display to zeros.  When a weighing 
that has been zeroed out is removed from the pan, a negative reading is displayed.  To 
return to zeros, press the ZERO switch. 
 

The Mode Switch 

Pressing the MODE switch starts the unit of weight cycle as follows: grams (g), carats 
(ct), pennyweights (dwt), troy ounces (ozt), and ounces (oz).  Press the MODE switch a 
second time when the desired unit of measure appears.  For Vapor Pro operation, verify 
that the balance is weighing in grams (g).  
 

The Send Switch 

The SEND button is not normally employed in everyday usage of the balance, although 
it is used in certain specific configuration procedures, as detailed later in this manual. 
 

The Function Switch 

Pressing the FUNCTION switch cycles the display through four functions as follows:  

PCS - front panel parts counting 

HI OK LO - check weighing 

CAL 1 - auto-calibration 

CAL 2 - factory set - 

DO NOT USE

 

CAL 2 is set at the factory and should never require further adjustment.  The procedure 
for CAL1 begins on page 9.  For the other two functions (PCS and HI OK LO), refer to 
the appendices beginning on page 19.
