To calibrate the
pump #3
in this channel follow the steps below. Refer to the picture in
“
Calibration With Precise Digital Scale and Stand/Holder
” for using the digital scale.
1) Turn ON the digital scale.
2) Wait a few seconds and next then zero-out the digital scale by clicking the
T (Tare)
button. Before starting measurements, the digital scale has to display 0.00g on the
LCD screen.
3) Make sure that digital scale is displaying [
g
] as the weight unit. If not then press the
M (Units)
button until you see [
g
] gram unit on the LCD screen.
4) From the Application, under the “
kHLab
” TAB, click the
Calib #3 pump
button.
The pump will start adding water to the calibration cylinder (vial).
5) After few dozen seconds
pump #3
will stop automatically. Write down the value
displayed on the digital scale LCD screen.
6) Add aquarium water sample to the kHLab module test/mixing cylindrical chamber
(about 3/4 capacity).
7) Dispose of the fluid from calibration cylinder (vial) and repeat above calibration
steps few times (recommended five times). Sort the results from highest to lowest,
ignore the highest and lowest and use the middle three results to determine the
average pump performance value.
EXAMPLE:
If after eliminating the highest and lowest recorded results you’re left with results of:
54.46g, 54.67, 54.37g, add them and divide by 3 and calculate arithmetic average.
This would be calculated as: (54.46g + 54.67g + 54.37g) / 3 = 163.5g / 3 = 54.5g
8) Save the calculated value by placing the final number in the field next to “
Calib #3
pump
” button in the application window and click
Save #3 water
9) Channel #3 calibration process has been completed.
