1. FEATURES

* For health reason, negative ( alkaline ) water

generator is used in the home and office popularly.

However seldom peoples know the intensity of

negative ( alkaline ) ions that are contained in the

water.

* NI-214 is the useful tester to measure the negative ion

potential value in the water.

* Kits included Negative Ion probe ( ORP probe ) with

the meter and the carrying case.

* Measurement range : 1999 mV to -1,999 mV.

* LCD display, data hold.

* Easy operation, compact size.

* Water resistance on the front panel.

* DC 9V battery ( 006P ).

4. MEASURING PROCEDURE

1)Connect the " Electrode plug " ( 3-7, Fig. 1 ) to the

" BNC socket " ( 3-4, Fig. 1 ).

2)Power on the instrument by using " Power ON/OFF

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

3)Use the hand to hold the " Electrode handle " ( 3-8,

Fig. 1 ), immerse the " Electrode sensing head " ( 3-9,

Fig. 1 ) into the measured water ( solution ), the

instrument will display the potential value of

Negative Ion Water in " mV " ( ORP value in " mV " ).

* Electrode ( attached ) is the

rough and durable ORP electrode.

However user should operate the

electrode very carefully.

* The electrode is the consumer

accessory, after the electrode is

used, if the damage of the

Electrode Sensing Head ( Spear

Tip Head ), it is without warranty.

4)After make the measurement, please rinse the electrode

in distilled water.

Data Hold

During the measurement, press the " Hold Button " ( 3-3,

Fig. 1 ) once will hold the measured value & the LCD will

display a " HOLD " symbol.

Press the " Hold Button " once again will release the data

hold function.

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 "

( 3-5, Fig. 1 ) on the rear cabinet.

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

and reinstall the battery cover again.

6. ELECTRODE STORAGE, CLEANING

and RECONDITIONING

6-1 Electrode Storage

When the readings are made infrequently, for example,

several days or weeks apart, the electrode can be stored

simply by replacing it in its soaker bottle. First, slide the

cap onto the electrode, then the o-ring, then insert the

electrode into the bottle and firmly tighten the cap. If

the solution in the soaker bottle is missing, fill the bottle

with pH 4 buffer. 6

6-2 Electrode Cleaning

Coating of the pH bulb can lead to erroneous readings

including shortened span. The type of coating will

determine the cleaning technique. Soft coatings can be

removed by vigorous stirring or by use of a squirt bottle.

Organic chemical or hard coatings should be chemically

removed. Only in extreme cases should the bulb me

mechanically cleaned as abrasion can lead to permanent

damage. If cleaning does not restore performance,

reconditioning may be tried.

7. CALIBRATION PROCEDURE

The meter along the electrode has been calibrated

carefully during manufacture. However, it may be

necessary to re-calibrate periodically. Particularly if the

instrument is used foe a long period or if the conductivity

electrode is changed. To re-calibrate the instrument,

follow the procedures shown below :

1)Prepare a " Standard ORP Calibration Solution " ( optional )

2)Connect the electrode into the meter.

3)Power ON the meter

4)Immerse the " Electrode sensing head " ( 3-9, Fig. 1)

into the calibration solution up to the immersion level.

Use the small screw driver to adjust the " Cal. VR "

( 3-6, Fig. 1 ) until the display reading value same as

the " Standard Calibration Solution " value.
