5-3 Calibration
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)Install the " Probe Plug " ( 5-1, Fig. 2 ) into the
" CD Socket " ( 3-13, Fig. 1 ).
3)Power on the meter by pressing " Power Button "
( 3-2, Fig. 1 ) once.
4)Hold the " Probe Handle " ( 5-2, Fig. 2 ) by hand
and let the " Sensing head " ( 5-2, Fig. 2 )
immersed wholly into the measured solution. Shake
the probe to let the probe's internal air bubble drift
out from the sensing head.
Display will show the conductivity mS ( uS ) values.
5)Use the two fingers to press the " REC Button " ( 3-4,
Fig 1 ) and " HOLD Button " ( 3-3, Fig. 1 ) at the same
time. the display will show the following screen as
example, release the both fingers.
