Enter the remaining constants for each depth. 

 

NOTE 

If the calibration sheet lists B and F values, instead of 
B*1000 and F*1000 values, then the calibration is in 
English, rather than metric, units. Therefore, the B and 
F values must be converted to metric values and 
multiplied by 1000 before they are entered into the 
gauge. A more direct method is to multiply the B and F 
values by 62.4298, then enter the resulting products into 
the gauge.

Memory Reset erases all data stored in the gauge and
