In order to make the EMO-1005 display show the desired engineering units, the most important thing
to know is the K-factor of the transmitter that is being monitored. The K-factor is the relationship
between the amount of impulses and the engineering unit.
To change the scaling just enter the number, (zero the display first) and to change the decimal point
location press the DP key. After having the decimal point in the correct location press the ENT key
once. Now, by pressing the SPC key the unit display can be changed to one of the following
engineering units: Imp, Gal, lit, cin, cc, lbs, kg, gr, mm, cm, Inch, ft, Oz, Rev.
Press Enter to exit KFT programming.
The default value for the KFT is 00010000 (Maximum= 65000)
The default engineering unit is Imp (Impulses)
For example a flowmeter's K-factor could be 1998 imp/Gal or 123.22 imp/lit. A rpm pickup could be
55.0 imp/rev.
In order to calculate the KFT multiplier for the EMO-1005 apply the following formula.
10000
KFT =
K-factor
where,
KFT is the number that should be entered for TOTALIZER SCALING in display 2.
K-factor is the number published by the manufacturer as the average K-factor of the
transmitter. If this is published in imp/gal the totalizer can still be set in, say cc's, by
converting the K-factor to imp/cc.
10000 is a constant.
For example:
A flowmeter has the K-factor 10666.0 imp/Gal and the display should show gallons/minute.
10000
KFT =
= 0.9376 Gal
10666.0 Gal
In the above example enter 9-3-7 (zero the display first, and don't enter the number 6) and then adjust
the decimal point by pressing DP until the point appears at the correct position. After pressing the ENT
key, the engineering unit may now be chosen by pressing the SPC key until the correct unit comes up.
Now, by pressing the ENT key the KFT number and engineering unit will be stored in memory.
