4. MEASURING PROCEDURE
4-1 Salt measurement
1)Turn on the meter by pressing the " Power Button "
( 3-3, Fig. 1 ) momentarily.
* Press the " Power Button " ( 3-3, Fig. 1 )
momentarily again will turn off the meter.
The " Display " ( 3-2, Fig. 1 ) will show the unit as :
0.00
%
Now the meter is ready for the measurement.
2)Hold the meter by hand and immerse the " Salt Sensing
Head " ( 3-6, Fig. 1 ) immersed wholly into the measured solution. Shake the " Sensing Head " to let the electrode's internal air bubble drift out from the " Sensing Head ". " Display " ( 3-2, Fig. 1 ) will show the salt value in and salt ( % weight value ).

Fig. 2
When make the measurement should immerse the " Sensing Head " immersed wholly into the measured solution.
3)The " Sensing Head " build in the temperature sensor
for the usage of automatic Temp. compensation. If the temperature of measured salt solution is changed, then it should take few minutes to let the display reading reach the stable value.
4-2 Data Hold
1)During the measurement, press the " Hold Button "
( 3-4, Fig. 1 ) momentarily to hold the measured value. The LCD will show a " HOLD " symbol.
2)Press the " Hold Button " once again to release the
data hold function.
4-3 Data Record ( Max., Min. reading )
1)The data record function records the maximum and
minimum readings. Press the " REC Button " ( 3-5, Fig. 1 ) momentarily to start the Data Record function, shows " REC " on the display.
2)With the " REC " symbol on the display.
a)Press the " REC Button " ( 3-5, Fig. 1 ) momentarily,
the " REC MAX " symbol along with the maximum value will appear on the display.

Page 8
b)Press the " REC Button " ( 3-5, Fig. 1 ) momentarily
again, the " REC MIN " symbol along with the minimum value will appear on the display.
* When display shows " REC MAX " or " REC MIN ",
press the " Hold Button " ( 3-4, Fig. 1 ) momentarily will delete the max. ( min. ) value, the display will show the " REC. " only and execute the memory function continuously.
c) To exit the memory record function, press the
" REC " button for 2 seconds at least. The display will revert to the current reading, not show " REC " indicator.
4-4 Auto power off management
The meter has built-in "Auto Power Shut-off " function in order to prolong battery life. The meter will switch off automatically if none of the buttons are pressed within 10 min..
5. CALIBRATION PROCEDURES
1)Power off, use the finger to press the " Hold button " continuously ( not release ) then power On . Until power on ( Display on ) then releasee fingers from the " Hold button ".
2)Insert the Probe head into the calibration standard solution.
3)Press the " Hold button " once, display will show " HOLD " indicator, press the " REC button " once, the upper display will show " CAL " within a short period. Then display will show

CAL
4)Use the " Up button " , " Down button " to select the desired calibration value, then wait about 5 second, the calibration data will saved into the memory circuit, and finish the calibration procedures.
6. REPLACEMENT OF BATTERY
1)When the 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 instruments instrument become inaccurate.
2)To replace the battery, rotate and remove the " Battery Cover " ( 3-1, Fig. 1 ), take out the old batteries, install new batteries :
DC 1.5V battery ( UM-4/AAA ) x 4 PCs.
3)When install the batteries, should make attention the battery polarity.
4)After install the batteries, reinstall the battery cover again.
