4. MEASURING PROCEDURE

1) Connect the ORP Electrode ( optional ) to the " BNC

socket " ( 3-5, Fig. 1 ).

2) Power on the instrument by pressing the " Power ON

Button " ( 3-2, Fig. 1 ).

3) Plug in the " BNC Plug of ORP Electrode ( optional ) "

( 3-10, Fig. 1 ) into the " BNC Socket " ( 3-5, Fig. 1 )

4) Place the ORP electrode ( optional ) into the measured

solution, the LCD Display ( 3-1, Fig. 1 ) will show the

ORP value in " mV " unit.

5) During the measurement, pressing the " Hold Button "

( 3-4, Fig. 1 ) will freeze the display value, at the same time

the LCD will show the " HOLD " indicator.

To release the Data Hold function, just pressing

the " Hold Button " again, then the " HOLD " indicator

will be disappeared and cancel the Data Hold function.

6) Power off the instrument by pressing the " Power OFF

Button " ( 3-3, Fig. 1 ).

Remark :

a. After make the measurement, please rinse the

electrode in distilled water.

3-6 Calibration VR

b. The meter build in one " Calibration VR "

( 3-6, Fig. 1 ) on the side case. However, the

complete calibration procedure was already

done when meter was produced. New

calibration procedure is not necessary except it

will be executed by the qualify technician people.

5. REPLACEMENT OF BATTERY

1) When the left corner of LCD display show " " ,

it is necessary to replace the battery. However, in-spec

measurement may still be made for several hours after

" Low Battery Indicator " appears before the

instrument become inaccurate.

2) To replace the battery, remove the " Battery Cover "

( 3-7, Fig. 1 ) on the rear cabinet.

3) Take out the battery, install a new one ( 006P DC 9V ) and

reinstall the battery cover again.
