password(In this process
, if password is not right, system will warn.) At last press “OK” key-press to switch
to menu interface(picture 15), After switching to menu interface, through pressing “MENU” key-press, shift
cursor to corresponding item menu, then press “OK” key-press to enter corresponding item.

(1). Conductivity(TDS) parameter setting(picture 16):
Under the menu interface(picture 15), press “MENU” key-press to shift the cursor to choose “TDS”
item, then p
ress “OK” key-press to enter ”TDS” parameter setting(picture 16).
Press “MENU” key-press to choose modified item, and press “ ” key-press to choose modified
place, and press “ ” key-press to amend the parameter. When amending is ok, press “OK”
key-p
ress for system’s confirmation. If back to main interface is necessary, press ”MENU” key-press
to shift cursor to icon at the right bottom of the LCD and press “OK” key-press to return to main
interface.
（
In the following item parameter setting process, the method is equivalent to the
conductivity(TDS) parameter setting’s.
）
TDS1: inlet water conductivity test.
Max: inlet water conductivity’s upper limit alarm parameter of TDS1.
Min: inlet water conductivit
y’s lower limit alarm parameter of TDS1.
Remark:
TDS1(hysteresis of inlet water conductivity =Max-Min) upper and lower alarm test only work when
power is on. When current test parameter > TDS1’s Max, the current test parameter will display and
system will
warn. System will stop warning when current test parameter <TDS1’s Max.
TDS2: RO water conductivity test.
Max: RO water conductivity’s upper limit alarm parameter of TDS2.
Min: RO water conductivity’s lower limit alarm parameter of TDS2.
Remark: When cur
rent test parameter of RO water > TDS2’s Max, the current test parameter will
display and system will warn. System will stop warning when current test parameter <TDS2’s Max.
EC: electrode parameter setting (Parameter setting is OK in factory. Additional parameter setting is
unnecessary.)
TCQ: temperature compensation parameter setting(Parameter setting is OK in factory. Additional
parameter setting is unnecessary.)

(2). Resistivity parameter setting
Under the menu interface(picture 15), press “MENU” key-press to shift the cursor to choose “Resist”
item, then press “OK” key-press to enter ” Resist”” parameter setting(picture 11).
Max: resistivity’s(Ultrapure polishing resin cartridge’ life
）
upper limit alarm parameter.
Min: resistivity’s(Ultrapure polishing resin cartridge’ life
）
lower limit alarm parameter
Remark:
The “Min” determines alarm of Ultrapure polishing resin cartridge’ life. When current test parameter of
