Range 2 ( 20 mS range ) calibration

1) Prepare a " 12.88 mS Calibration Solution ".

2) Immerse the head of " Conductivity Probe " ( 3-17, Fig. 1 )

into the 12.88 mS solution up to the immersion level.

3) Select the range to the " 20 mS " position.

4) Set the temperature coefficient factor value to " 2.0% per

蚓 "

5) At the same time push the following buttons together :

a. REC.( MAX./MIN. ) Button ( 3-3, Fig. 1 )

b. HOLD Button ( 3-4, Fig. 1 )

The upper display will show the flashing text of " CAL ".

The low display will show the flashing text of " 12.88 "

6) Please release the two buttons when the display shows as

above and start flashing and then when the text stop

flashing, the range 2 will be calibrated to 12.88 mS

( There maybe a little deviation, and it is normal ).

After released two buttons but before the text

(CAL, 12.88 ) stop flashing, if push the " HOLD Button

" will cancel the calibration procedures, the meter will

return to previous calibration value.
