Unit Type	Selectable Units	Units Register	Converting registers to	Register value for 1
			unit values	unit
Pressure	Percent	n/a	Pressure = Register	1 = 1% Pressure
Pressure	psi	403208 = 0	Pressure = Register	1	= 1 psi
	Bar	403208 = 1	Pressure = Register/10	10 = 1.0 Bar
	MPa	403208 = 2	Pressure =	100 = 1.00 Mpa
			Register/100
Speed	Cycles/min	n/a	Speed = Register/10	10 = 1.0 cycle/min
Flow	Liters/min	403210 = 0	Flow = Register/10	10 = 1.0 L/min
	Gallons/min	403210 = 1	Flow = Register/10	10 = 1.0 Gal/min
	cc/min	403210 = 2	Flow = Register	1	= 1 cc/min
	oz/min	403210 = 3	Flow = Register	1	= 1 oz/min
	Cycles/min	403210 = 4	Flow = Register/10	10 = 1.0 cycle/min
Volume✝	Liters	403209 = 0	Volume = 1000*High +	0	(High) / 10 (Low) =
			Low/10	1.0 L
	Gallons	403209 = 1	Volume = 1000*High +	0	(High) / 10 (Low) =
			Low/10	1.0 Gal
Cycles✝✝	Pump Cycles	n/a	Cycles = 10000*High	0	(High) / 1 (Low) = 1
			+ Low	cycle

✝Example of converting volume register reading to units: If the reading for register 404106 (volume high word) is 12, and the reading for register 404107 (volume low word) is 34, the volume is 12003.4 liters. 12 * 1000 + 34/10 = 12003.4.

✝✝Example of converting cycles register reading to units: If the reading for register 404108 (cycles high word) is 75, and the reading for register 404109 (cycles low word) is 8000, the volume is 758,000 cycles. 75 * 10000 + 8000 = 758000.
