1. Bubuka
The Extech DO600 Waterproof ExStik II Dissolved Oxygen Meter is designed for precise measurement of dissolved oxygen levels. It displays oxygen concentration as a percentage of saturation (0 to 200%) or as a concentration in parts per million (ppm) or milligrams per liter (mg/L) (0 to 20.00 ppm/mg/L). Key features include adjustable altitude compensation, adjustable salinity compensation, and an analog bargraph for trend indication. This manual provides instructions for the proper setup, operation, and maintenance of your DO600 meter.

4. Setélan
4.1. Pamasangan batré
The DO600 meter uses four 3V CR-2032 batteries. These are typically pre-installed. If replacement is necessary:
- Twist off the battery compartment cap located at the top of the meter.
- Remove the old batteries, noting their polarity.
- Insert new CR-2032 batteries with the correct polarity.
- Securely replace the battery compartment cap to maintain the waterproof seal.
4.2. Persiapan Éléktroda
Before first use or after prolonged storage, the DO electrode requires preparation:
- Unscrew the protective sensor cap from the electrode.
- Fill the spare membrane cap with the provided electrolyte solution. Ensure no air bubbles are trapped.
- Carefully screw the membrane cap onto the electrode, ensuring the membrane is taut and free of wrinkles.
- Allow the electrode to stabilize for approximately 15-30 minutes in the electrolyte solution before calibration.

5.2. Kalibrasi
Regular calibration ensures accurate readings. Calibrate the meter in air-saturated water or a known standard solution.
- Ensure the electrode is prepared as described in Section 4.2.
- Immerse the electrode in air-saturated water (e.g., tap water stirred vigorously for several minutes) or a DO standard solution.
- Pencét jeung tahan tombol CAL / NGARETAK pencét tombol "CAL" nepi ka muncul dina layar.
- The meter will automatically recognize the calibration point and adjust. Wait for the reading to stabilize and for the calibration indicator to confirm completion.
5.3. Nyandak Pangukuran
To measure dissolved oxygen:
- Daya dina méteran.
- Celupkeun éléktroda kana sample larutan. Pastikeun mémbran tilelep sapinuhna sareng bébas tina gelembung hawa.
- Gently stir the electrode in the sample to ensure proper flow across the membrane.
- Wait for the reading on the LCD display to stabilize. The display will show both dissolved oxygen and temperature.
- Pencét éta MODE / NGANGGO button to cycle between % saturation and ppm (mg/L) readings.
- To hold a reading, briefly press the MODE / NGANGGO tombol. Pencét deui pikeun ngaleupaskeun.

5.4. Altitude Compensation
Dissolved oxygen saturation levels are affected by altitude. The DO600 allows for manual adjustment:
- Refer to the meter's full instruction manual for specific steps to enter and adjust altitude compensation (0 to 20,000 feet in 1,000 ft. increments).
5.5. Salinity Compensation
Salinity also influences dissolved oxygen levels. The DO600 provides adjustable salinity compensation:
- Consult the meter's comprehensive manual for detailed instructions on setting salinity compensation (0 to 50 ppt).

6.1. Pabersihan sareng Panyimpenan Éléktroda
To maintain electrode performance:
- Bilas éléktroda ku cai sulingan sanggeus unggal pamakéan.
- If the membrane becomes fouled, gently clean it with a soft cloth or cotton swab. Replace the membrane cap if it is damaged or heavily contaminated.
- When storing, ensure the protective sensor cap is filled with electrolyte solution to keep the membrane hydrated.
