Finish Thompson FM2000 Series - Manual (Page 6)

For example, the specific gravity on the MSDS for 93% sulfuric acid is shown as 1.84. 8.33 pounds per gallon x 1.84 = 15.33
pounds per gallon (density) for 93% sulfuric acid.
f. Divide the net fluid weight by the fluid density to determine volume. Record the known volume _____.
For example, the net weight is 41.65 pounds; the fluid is water with a density of 8.33 pounds per gallon; 41.65 divided by
8.33 = 5 (gallons)
g. Divide the known volume by the reading on the meter. Record this multiplier _____
For example, if using a five-gallon container and the meter reads 5.2 gallons the multiplier is .96.
Step Three – Calculate new Rate Scale Factor
For gallons per minute
NOTE: Factory default Rate Scale Factor is 018.458
Multiply multiplier factor by factory rate scale factor.
For example, .96 x 018.458 = 017.720
Record the number here ____________ and also below in “Step Six” part b.
For liters per minute
NOTE: Factory default Rate Scale Factor is 069.872
Multiply multiplier factor by factory rate scale factor.
For example, .96 x 069.872 = 067.077
Record the number here ____________ and also below in “Step Six” part b.
Step Four – Calculate new Total Scale Factor
For gallons per minute
NOTE: Factory default Total Scale Factor is 00.3076
Take the Rate Scale Factor from Step three and divide by 60.
For example if the Rate Scale factor from Step three is 017.720, the Total Scale Factor is 00.2953
Record the number here _____ and also below in “Step Six” part g.
For liters per minute
NOTE: Factory default Total Scale Factor is 01.1645
Take the Rate Scale Factor from Step three and divide by 60.
For example if the Rate Scale factor from Step three is 067.077, the Total Scale Factor is 01.1180
Record the number here _____ and also below in “Step Six” part g.
Step Five – Enter programming menu
To enter programming mode, press and hold the button on the front of the meter for at least 2 seconds.
Step Six – Enter the Rate Scale Factor and Total Scale Factors
NOTE: Meter automatically exits programming mode after 20 seconds of button inactivity. Any changes made will be lost (new value will not be
stored).
a) Enter the Rate Scale Factor from Step Three.
Rate scale factor from “Step Three”
b) Press the button to select the digit to be modified. The selected digit will blink. The decimal point will blink after all the numbers have
been cycled through. Do not change the decimal point.
c) Press the button to modify the selected digit. Repeat the process until all digits have been modified.
