Sending floating point

numbers

For ease of understanding we are calling fixed decimal numbers “floating point

numbers.” We are aware they are not technically floating point numbers.

When transmitting a ﬂoating point number to any of these 3 register blocks, the number

must ﬁrst be multiplied by 100. This would have the effect of removing the ﬂoating point.

Internally the EC OEM

™

will divide the number by 100, converting it back into a ﬂoating

point number.

Example

Setting a conductivity probe type of K = 4.56

4.56 X 100 = 456

Transmit the number 456 to the Set Probe Type Registers

Setting a calibration value of 14.56µs

14.56 X 100 =1456

Transmit the number 1456 to the Calibration Value Registers

Setting a temperature compensation value of 99.06˚C

99.06 X 100 = 9906

Transmit the number 9906 to the Temperature Compensation Registers

When reading back a value stored in one of these 3 register blocks

the value must be divided by 100 to return it to its originally intended value.
