refer to chapter 10-7 page 26.

Change the Temp. Coefficient Factor

The default Temp. compensation factor value of the

measurement solution is to 2.0% per . If intend to℃

change it, please refer to chapter 10-8, page 27.

Zero adjustment

If the probe not immerse the measurement solution and

display not show zero value, pressing the " Button "▲

( 3-5, Fig. 1 ) continuously at least 10 seconds will let

display show zero. The zero function only valid for the

200 uS range and the not zero value is < 2.0 uS.

5-2 TDS ( PPM ) measurement

The measuring procedures are same as above

5-1 Conductivity ( uS, mS ) measurement,

except to change the display unit from uS, mS to PPM.

10-6 Decimal point of SD card setting

The numerical data structure of SD card is default used
the " . " as the decimal, for example "20.6" "1000.53" .
But in certain countries ( Europe ...) is used the " , " as
the decimal point, for example " 20,6 " "1000,53".
Under such situation, it should change the Decimal
character at first.

When the lower display show " dEC "

1)Use the " Button " ( 3-5, Fig. 1 ) or " Button "▲▼

11. POWER SUPPLY from DC

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

ADAPTER

The meter also can supply the power supply from the
DC 9V Power Adapter ( optional ). Insert the plug of
Power Adapter into " DC 9V Power Adapter Input Socket
" ( 3-14, Fig. 1 ). The meter will permanent power ON
when use the DC ADAPTER power supply ( The power
Button function is disable ).

12. BATTERY REPLACEMENT

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)Loose the screws of the " Battery Cover " ( 3-11, Fig. 1 )

and take away the " Battery Cover " from the instrument

and remove the battery.

3)Replace with DC 1.5 V battery ( UM3, AA,

Alkaline/heavy duty ) x 6 PCs, and reinstate the cover.

4)Make sure the battery cover is secured after

changing batteries.

13. SYSTEM RESET

If the meter happen the troubles such as :

CPU system is hold ( for example, the key button can

not be operated... ).

Then make the system RESET will fix the problem.
The system RESET procedures will be either following
method :

During the power on, use a pin to press the " Reset Button "

( 3-15, Fig. 1 ) once a while will reset the circuit system.

14. RS232 PC SERIAL INTERFACE

The instrument has RS232 PC serial interface via a 3.5
mm terminal ( 3-16, Fig. 1 ).

The data output is a 16 digit stream which can be
utilized for user's specific application.

A RS232 lead with the following connection will be
required to link the instrument with the PC serial port.

The 16 digits data stream will be displayed in the
following format :

D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0

Each digit indicates the following status :

D15 Start Word
D14 4
D13 When send the upper display data = 1

When send the lower display data = 2

D12, D11 Annunciator for Display

uS = 13 mS = 14 PPM = 19
% = 03

D10 Polarity

0 = Positive 1 = Negative

D9 Decimal Point(DP), position from right to the

left
0 = No DP, 1= 1 DP, 2 = 2 DP, 3 = 3 DP

D8 to D1 Display reading, D1 = LSD, D8 = MSD

For example :

If the display reading is 1234, then D8 to
D1 is : 00001234
