select:
P-3 enter “3.33” estimated empty distance to transducer
P-6 enter option “2”, 4 to 20 mA
P-7 enter option “1”, decimal location for head display max. 1 digit after decimal
P-8 enter option “1”, relay 1 - alarm function
P-9 enter “1.8”, relay 1 - alarm ON
P-10 enter “1.5”, relay 1 - alarm OFF
P-11 enter option “1”, relay 2 - alarm function
P-12 enter “0”, relay 2 - alarm ON
P-13 enter “.3”, relay 2 - alarm OFF
P-14 enter option “13”, relay 3 - time sampler contact

press
at least 5 times to insure that the HydroRanger I will obtain a stable
ultrasonic measurement. The resultant reading will be the
apparent head
with respect to the
estimated P-3 = 3.33 ft.
Enter “physical head measurement”, over the displayed value previously
obtained. This is the true head measurement from a wall gauge, dipstick or
stilling well, taken at the same time as the ultrasonic measurement and rep-
resenting the same head measurement point as seen by the transducer.
The physical head measurement must not be in the near blanking zone. An
offset value, which is the apparent head minus the true head, is automat-
ically calculated and entered into P-62. P-62 can only be cleared by P-47.
P-48 enter “5.2”, low head cutoff is 5.2% of P-45. Flow for head
below 1" (40 thousand gal./day) will not be totalized
1" = 0.052 = 5.2%
