Numerical after "c" ( such as 46.33 ) is the modified flow coefficient (k) value, the number of
flashes that can be modified, and modify the scope: 0 to 9, the position can be shifted by
press the “CALIBRATE” button shortly
To press “ DISPLAY” shortly can increase the numerical from 0 to 9, increase only , can not
reduce.
After modification, press “DISPLAY” and “CALIBRATE” buttons simultaneously, it can
return to normal working status.
User manual flow coefficient (k) calibration correction formula:
When the user found that the actual traffic flowed liquid flow has a larger error with
displayed flow, using the following formula to re-calculated k value

Users to manually modify the k value, for example:
Clear "0" TTL1 value or remove the batteries, to clear TTL1, TTL2 "0", fitted with batteries,
button is shifted to TTL1 status, start the measurement of liquid flow, the flowed liquid
enters into the standard cylinder. Record the displayed flow value and graduated cylinder
