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.
