6-3 Calibration Conductivity
1.
Prepare the standard conductivity solution (optional) For example:
2 mS range calibration solution:
1.413 mS Conductivity Standard Solution, CD-14
200 uS range calibration solution:
80 uS Conductivity Standard Solution
20 mS range calibration solution:
12.88 mS Conductivity Standard Solution
Or other Conductivity Standard Solution
2.
Connect the conductivity
Probe (CDPB-03) (6-1, Fig.3) into the "
CD
” Socket (3-15, Fig. 1).
3.
Use the "
Function”
button, step to the
”
Cd
” function. See pkt. 4
4.
Hold the electrode handle (6-2, Fig. 2) by hand and let the sensing head (6-3, Fig. 2) immersed wholly
into the measured solution and little shake the electrode, to let the probe's internal air bubble drift out
from the sensing head
5.
The Display will show the conductivity mS (uS) values.
6.
Use two fingers to press the "▲ Button" (3-5, Fig 1) and "▼ Button" (3-6, Fig. 1) at the same time.
Until Display shows the following screen
then release the both fingers.
7.
Pressure within 3 second the "
Enter
" button (3-8, Fig.1) the measuring value will present on both
upper and lower Display. Use "▲ Button" (3-5, Fig.1), "▼ Button" ( 3-6, Fig. 1 ) to adjust the up display
value exact same as the standard conductivity value. Press the "Enter Button" ( 3-8. Fig.1) will save
the calibration data and finish the calibration procedures.
*
If only intend to make the one point calibration, just execute the 2 mS range (1.413 mS Cal.) is
enough.
*
Multi-points calibration procedures should execute the 2 mS range (1.413 mS Cal.) calibration at first,
then make other ranges (20 uS range, 20 mS range or 200 mS range) calibration procedures following
if necessary.
7. SALT MEASURING and CALIBRATION
7-1 Salt Measurement
1.
Connect the conductivity
Probe (CDPB-03) (6-1, Fig.3) into the "
CD
”
Socket (3-15, Fig.1)
2.
Use the "
Function”
Button, step to
the”
SALt
” function. See pkt. 4.
3.
Hold the electrode handle (7-2, Fig. 4) by hand and let the sensing
head (7-3, Fig. 4) immersed wholly into the measured solution and
little shake the electrode, to let the probe's internal air bubble drift out
from the sensing head
4.
Display will show the Salt values (% weight).
7-2 Calibration
If the conductivity range already make the calibration completely then the Salt measurement is
not necessary to make the calibration again.
