操作說明
1) 依電壓規格指示接上電源。選擇高於設定值啟動控制電源者，
請將 HI/LO 開關切於" HI-A " 位置。若選擇低於設定值啟動控
制電源者請將 HI/LO 開關切於" LO-A "位置。
2) 將pH 電極裝入 pH 輸入端 (BNC接頭插入後，右轉到底)。
3) 將選擇開關位置切到 " pH " 位置。
4) 將pH 電極以蒸餾水稍做清洗後擦乾再放入 pH7 校正液中，等
待數秒鐘待顯示值穩定後，調整 " pH7 " 旋鈕，使顯示的數值為
7.00。
5) 將pH 電極從 pH7 校正液中取出以蒸餾水稍作清洗後擦乾，將
pH 電極放入 pH4 校正液中，等待數秒鐘待顯示值穩定後，調
整" pH4 " 旋鈕，使顯示的值為 4.00。
（此步驟 4、5 為新電極使用前必須的校正步驟）
6) 完成校正後，可將電極放入待測水中，將pH/SET功能開關位置
切到 " SET " 設定位置。(此時控制電源會自動關閉，以避免無
預期的啟動控制，造成危險)
7) 調整 SET 的旋鈕，使顯示的數字到達到所需要設定的 pH 值。
(若開關置於" HI-A "，測試值高於設定值時會啟動控制信號。若
開關置於" LO-A "，測試值低於設定值時會啟動控制信號)，設 定
完後請將開關切回 " pH " 測量位置。
清潔保養
1) pH 電極置於水中不可超過電極帽高度，且定期(1 ~ 2星期)以軟毛
牙刷輕刷清洗。不用時，電極請置於有3莫爾 KCL保存液之封
套內，若有結晶乃屬正常現象。擦拭儀器本體時，應避免水濺
入內部，造成損壞。
2) pH 測試值，應待穩定平衡後，所讀出的值才是正確值。
3) pH 電極為一精密之玻璃製品，請勿敲擊。
4) pH 電極請勿用手及布類及酒精擦拭。

備註
為保護控制的設備不受連續頻繁開關動作而損壞，設有延遲啟動
功能，控制點會有高於設定值一些(0.03~0.05pH)才動作，且低於設
定值一些(0.03~0.05pH)才關閉的保護狀態(設定HI啟動狀態下)。
為什麼要測pH值
pH值代表水質呈現酸或鹼性的狀態 (pH值等於7為中性，pH值大於
7為鹼性，pH值小於7為酸性)，大部分的觀賞魚都能適應生活在pH
值＝7左右的中性水質，但許多魚種有特別的水質偏好。
例如：
pH＜7的魚種: 如七彩神仙，亞馬遜燈科魚等，喜好pH＝6.0到6.5
的水質。
pH＞7的魚種: 如海水魚喜好pH＝8.4的水質，非洲慈鯛喜好pH7.5
到8.0的水質。
※所以對的pH值，才能把魚養對！
水質過酸時怎麼辦
應該調升水中的pH值，常見調整方法可以採用：
使用珊瑚砂底床，添加pH或KH、GH調高液(粉)劑或錠片，使用陰
離子交換樹脂等方法。
水質過鹼時怎麼辦
應該調降水中的pH值，常見調整方法可以採用：
使用弱酸性底土底床，增加 RO(逆滲透)水使用比例，使用陽離子
交換樹脂，添加pH調低液(粉)等方法。

before use.
FRONT PANEL DESCRIPTION
1) Display 6) pH / SET function switch
2) pH7 calibrate adjustment knob 7) HI / LO action function switch
3) pH4 calibrate adjustment knob 8) Electrode BNC input terminal
4) SET Adjustment knob 9) Control output socket
5) Indicator of output in action 10) AC power plug
OPERATING (CALIBRATION)
1) Connecting AC power supply.
2) Connecting the pH electrode into the pH input terminal socket.
3) Turn the pH/SET switch to "pH" position.
4) Put the pH electrode into the standard buffer solution pH7.00. Waiting a few
seconds for stable reading and adjust the "pH7" knob until the display
reading is exact on 7.00. Then take away the pH electrode from buffer
solution, and clean the electrode with distilled water.
5) Put the pH electrode into the standard buffer solution pH4.01, Waiting for a
few seconds for stable reading and adjust the "pH4" knob until the display
reading is exact on the buffer 4.01. (You also can calibrate pH10.00 by
using the buffer solution pH10.00 instead of pH4.00 buffer solution.)
(Make sure the step 4 to 5 are carried out when use a new pH
electrode.)
6) After calibrating the pH electrode, put the electrode into the water of tank.
Turn the pH/SET function switch to “SET” position to adjust the setting point.
7) Adjust the "SET" knob until the display reading exact meet your requirement.
Slide the pH/SET function switch to "pH" position for measuring. (Slide the HI/LO
switch to "HI" position will switch on the output control when pH measuring value
goes above the setting value. Slide the HI/LO switch to "LO" position will switch
on the output control when pH measuring value goes below the set value.)
CLEANING AND MAINTENANCE
1) The immersed level for electrode should not be higher than the electrode
cap. (When use the refillable electrode, the level should be lower than
filling open to avoid the water entering into the open and cause damage.)
It had better cleaning the pH electrode sensor with soft brush and
calibrating the pH electrode every 2-3 weeks to keep the test accuracy.
Please keep the electrode in the storage bottle with 3M KCL buffer (or
standard buffer solution pH4.0) solution, the crystallization is normal for
the keeping.
2) pH electrode is accurate glass product, please do not knock it, and do not
use finger, cloth and alcohol to clean it to avoid the damage.
3) There is protection "dead band" which will delay to switch on output control
when the pH measuring value goes above 3-5 digits of the set value. The
output control will switch off when the pH measuring value goes below 3-5
digits of the set value. (HI/LO switch in "HI" position.)
4) The output control will automatically turned off when slide the pH/SET
function is switched in "SET" position to adjust the setting valve.
5) Indoor uses only.

WHY SHOULD WE KNOW pH RANGE
pH value shows the acid or alkaline state of water (pH value equals 7
is neutral, it is alkaline as pH value is greater than 7, and acid as pH
value is less than 7), most of the fish can adapt to life in water around
pH =7, but many species have special water preferences.
Such as:
species of pH < 7: Discus, Amazon cardinals, preferences for
pH=6.0 to 6.5.
species of pH＞7: Marine fish preferences for pH＝8.4 and
African cichlids preferences for pH 7.5 to 8.0。
※THE RIGHT pH RANGE KEEP THE FISH RIGHT！
WHAT TO DO AS pH RANGE IS TOO LOW
The pH range of water should be shifted up, the methods of
adjustment you can take: Use coral gravels substrate, anion
exchange resin, add additives of powder, solution or tablets which
can shift pH、KH and GH range up.
WHAT TO DO AS pH RANGE IS TOO HIGH
The pH range in water should be shifted down, the methods of
adjustment you can take: Use weak-acid gravels substrate, cation
exchange resin and higher portion of reverse osmosis water. Add
additives of powder or solution which can shift pH range down.
