CHECK THE WATER LEVEL FREQUENCY (In QC Test Mode)
The display will show a number (usually between 25 and 65) to indicate the water
level frequency. In QC Test Mode, multiply the 2-digit readout by 0.1 and add 20
to determine the frequency. For example, the display shows 65 at steps 4, 5, 6, 7,
10, and 11 in the test mode. Multiply 65 by 0.1 to get 6.5, add 20 to get 26.5 kH
which is the water level frequency.
