DECIMAL PLACE LOCATIONS

11. DECIMAL SHIFT

The DECIMAL SHIFT feature is used to increase system accuracy at low application rates. Shifting
of the decimal point is done during the entry of METER CAL. After entering METER CAL mode,

depress the decimal shift

, enter the meter calibration constant number, and depress .

The sequence to unshift the decimals while in METER CAL is to enter the meter calibration constant

number and depress . The following table illustrates how shifting the decimal point can
increase system accuracy.
