  • Page 9: Ph Measurement

    Step 4 Wait until the reading is stabilized, then take a new measurement. If your application is to measure dissolved oxygen in aqua farm, it is suggested to measure at least 1 meter deep and do it regularly at fixed time, fixed location and fixed water deep to get proper data for comparison.

  • Page 10: Conductivity Measurement

    CONDUCTIVITY MEASUREMENT Please put on anti-collision hood to provide better protection. There is no need to remove hood even when you plan to do calibration. (Refer to pg. 20) Step 1 Rinse the probe with de-ionized or distilled water to remove impurities adhering on the electrode.

  • Page 11: Memory Record

    MEMORY RECORD In the normal mode, press MEM key can memorize up to 99 points records. The M EMO number will be displayed on the screen. “FUL” on the screen when the 99 points memories are full. NOTE: DO value in % unit can’t be memorized, Please switch to mg/I (ppm) mode before proceed memory recording.

  • Page 12: Setup

    SETUP This meter has the advanced setup mode which allows you to customize and check your meter’s preferences and defaults. If you would like to change the parameters, please press “SET” for more than 2 seconds to enter the setup mode when the meter is in the measurement mode.

  • Page 13: P10 Memory Clear - Clr Adjust

    P10 Memory Clear-CLr (adjustable) P10 is used to clear the stored data from meters. 1. Enter setup mode to select memory clear function. CLr P10 will be displayed on the LCD (Fig 1). Press ENTER for P11 setting (Fig 2). The default “no” icon will flash on the display and P11 will be displayed on the upper part of the screen.

  • Page 14: P60 Do Review And Set Parameters Adjustable

    P60 DO Review and Set parameters adjustable P60 is used to review and customize the suitable setting for D.O. Measuring. For example, if the measured target is sea water or in plateau, it is required to setup correct salinity value and altitude. 1.

  • Page 16: P20 Ph Electrode Slope Review

    P20 PH Electrode Slope (Review) P20 is used to view the pH electrode data (slope value) and used this data to judge the availability of p H probe. 1. Enter setup mode, press △ or ▽ key to enter the ELE P20 (Fig 4) display. 2.

  • Page 17: P40 Cond. Cell Constant Review

    P40 Cond. Cell Constant (Review) P40 is used to review the current cell constant at different 4 ranges. This value should be between 0.8 to 1.2. 1. Enter to setup mode and press △ or ▽ key in the setup mode to check CEL P40 display (Fig 8).

  • Page 18: P50 Cond. Tds Factor Adjustable

    P50 Cond. TDS factor (Adjustable) P50 is used to customize the factor to convert conductivity into TDS value. 1. Enter to setup mode and press △ or ▽ key in the setup mode to check td F P50 display. 2. Press ENTER key to enter and press △ or ▽ to adjust. The default is 0.50 and adjustable range is 0.30 -1.00.

    P10 to P70 summary w/default value CALIBRATION DO% SATURATION CALIBRATION For accurate reading, before each operating and after replacing the membrane set, calibration is highly recommended. No need to remove anti-collision hood before calibration. Calibration Steps 1. In normal mode, switch the D.O. Unit to O/o and h old the probe in air, wait for few minutes until the reading is stabilized.

  • Page 20: Calibration Ph Probe

    FIRST TIME LONG TERM WARM UP While following condition happens, please turn on the meter and wait for about one hour until the reading on LCD is stabilized, then follow the steps in above section to run calibration. (1) D.O. probe has just been plugged into the meter. (2) The membrane set has been replaced.

    5. Once the probe auto recognizes the pH buffer. For example, 7.01, the “CAL” and 7.01 will flash. (Fig 19) 6. If the auto recognized value is different from your standard buffer, pressing △ or ▽ key to adjust. 7. Wait for 30 seconds or pressing ENTER key, SA (Fig 20) will be displayed on the LCD to indicate the calibration is saved.
  • Page 22 DO NOT reuse the calibration solution. Contaminants in the solution will affect the calibration and the accuracy. Be sure to use fresh solution each time. For Conductivity calibration, you only need to do single point calibration. The previous calibration data will be replaced after re-calibration. For example, if you previously calibrated conductivity meter at 14 13 uS in the 0 to 1999 uS range, when you re- calibrate it at 1500 u S again (also in 0-1999u S range), the previous 14 13uS will be replaced in this range (0-1999u S).
  • Page 23 6. Press CAL key more than 2 seconds to enter calibration. The probe will automatically detect the conductivity solution value and the value will be flashed on the LCD. (Fig 21) Press the △ or ▽ key to adjust the value on the LCD to match the standard calibration value.

    9. Always use clean water to wash before immersing into different buffer. NOTE: If you would like to exit the conductivity calibration mode without saving, please press CAL/ESC key instead and it will retain the meter’s previous calibration data for the current range.
  • Page 25 HOW TO CLEAN THE ELECTRODE If too many residues have been found on electrode working area, it is suggested to clean the electrode as too many residues attached might disturb the chemical reaction during measuring. You can do membrane change and electrolyte refill together. 1.
  • Page 26 4. After scrap off the white residues, use clean water to wash away the remaining impurities. HOW TO REPLACE MEMBRANE SET a) Please replace membrane set when any of following situation occurs: b) The probe has been used for >1 year c) Seeing error code E2/E3 but the probe central working area is still clean.

    (5) Secure and install the new membrane set on the probe properly. After instaIIing the new membrane set with electrolyte fil led, it is normal to found some small bubbles inside of the membrane. (6) Proceed “calibration” as above section after replace the membrane set.

  • Page 28: Troubleshooting

    TROUBLE SHOOTING Can't power on 1. Didn't press the power key properly 2. Batteries are not installed or are not installed properly Solution: 1. Press power key for more than 0.3 seconds to turn on the device. 2. Check whether batteries are in good contact and correct polarity. You can also remove the batteries >10 mins and then install the batteries again.
  • Page 29 • For D.O, probe, connect the D.O probe with meter, turn on the meter and leave it for at least one day to activate the D.O. Probe, and then proceed the D.O. calibration. Keep the D.O. Probe connected with meter after using is suggested. Besides, check if the probe electrode requires routine maintenance.
  • Page 30 Error code - - - 1. - - means the probe isn't plug. Solution: 1. Check the probe plug again, make sure the contact is good and tight. 2. If probe is well plugged but still seeing - - -, turn off device and power on again to have device link to probe again.
