The BC1200 has the capability to switch between 2 different calibration factors.  To change between the calibrations remove the computer from the flow probe head by twisting 45 degrees counter clockwise and lifting.  The indented gray button in the upper left corner on the back is to switch between CAL I and CAL II. In the upper left corner of the display, I is displayed for CAL I and II is displayed for CAL II.

I = ft/sec, calibration # = 0053
II = m/sec, calibration # = 0016

The indented gray button on the upper right is used to enter the calibration mode.  Press and hold it for 5 seconds to enter calibration mode.

(Calibration values are factory set. Resetting is only required after changing the battery.)

  • Press bottom button until CLOCK or TOTALODO is not displayed on screen.

  • Set the calibration factors as follows:
    • Feet/second: 0053 (CAL I)
    • Meters/second: 0016 (CAL II)
  • Press indented right button on back for one second to store.
Repeat above procedure for Cal II.  (Only the cal number will be required)

The Flow Probe computer has a simple 2-button operation.  The bottom button scrolls between functions and the top button resets the function .s value.  Pressing the top button for 3 seconds zeros the average and maximum velocities.  With a little practice, the buttons can be pushed with the hand holding the top of the probe.

The computer functions are as follows:
  • Velocity: The upper display number is the instantaneous velocity to the nearest .5 foot (or meter, depending on units being used) per second.
  • The lower display number is used for the following functions:
    • average velocity(AVGSPEED)
    • maximum velocity(MAXSPEED)
    • stop watch(STPWATCH)
    • CLOCK
  • The bottom button scrolls between these functions, and also DIST/DAY, RIDETIME, TRIP UP, and TOTALODO which are not used for this application.
  • Push the top button for 3 seconds to reset the displayed function.  Push for 5 seconds to reset all velocity functions.
  • Stop watch: While STPWATCH is displayed, pressing the top button once will start the stop watch.  Pressing a second time stops the watch.  Holding the button for 3 seconds clears it.
  • Clock: The computer returns to the clock function after a period of inactivity for the probe.
