3. Gwybodaeth Diogelwch

Darllenwch a deallwch yr holl gyfarwyddiadau diogelwch cyn defnyddio'r ddyfais. Gall methu â gwneud hynny arwain at anaf neu ddifrod i'r cynnyrch.

• Cadwch y ddyfais allan o gyrraedd plant.
• Do not immerse the main meter unit in water or other liquids. The pH probe is designed for immersion, but the main unit is not waterproof.
• Handle the pH electrode with care. It is a delicate component.
• Peidiwch â cheisio agor na newid y ddyfais. Cyfeiriwch yr holl waith cynnal a chadw at bersonél cymwys.
• Cael gwared ar fatris yn unol â rheoliadau lleol.

4. Cynnwys Pecyn

Gwiriwch fod yr holl eitemau yn bresennol yn y pecyn:

• VOLTCRAFT PH-100 ATC pH-Meter Unit
• pH Electrode Probe
• Llawlyfr Defnyddiwr (y ddogfen hon)
• Note: 3 AAA batteries are required for operation and may not be included.

5. Gosod

5.1. Gosod Batri

1. Lleolwch glawr adran y batri ar gefn y mesurydd.
2. Slide or unscrew the cover to open the compartment.
3. Mewnosodwch 3 fatri AAA, gan sicrhau'r polaredd cywir (+/-).
4. Amnewid y clawr adran batri yn ddiogel.

5.2. Connecting the pH Probe

1. Carefully remove the protective cap from the pH electrode probe.
2. Connect the BNC connector of the pH probe to the corresponding port on the top of the meter unit. Twist gently until it is secure.
3. Ensure the connection is firm to prevent signal interference.

6. Gweithrediad

6.1. Pweru Ymlaen / I ffwrdd

• I droi’r mesurydd ymlaen, pwyswch y ON botwm.
• To power off the meter, press the ODDI AR botwm.

6.2. Cymryd Mesur

1. Ensure the meter is powered on and the probe is connected.
2. Rinse the pH electrode with distilled water before each measurement.
3. Immerse the pH electrode into the sample solution, ensuring the bulb is fully submerged.
4. Gently stir the solution and wait for the reading on the LCD display to stabilize.
5. Record the stable pH value.

6.3. Using the HOLD Function

• Yn ystod mesuriad, pwyswch y DALWCH botwm i rewi'r darlleniad cyfredol ar yr arddangosfa.
• Gwasgwch y DALWCH botwm eto i ryddhau'r darlleniad a dychwelyd i fesuriad byw.

7. graddnodi

Regular calibration is essential for maintaining the accuracy of your pH-meter. It is recommended to calibrate the device before initial use and periodically thereafter, especially if precise measurements are critical or if the meter has been stored for an extended period.

7.1. Calibration Procedure (General Guidelines)

The VOLTCRAFT PH-100 ATC typically requires a two-point calibration using standard buffer solutions. Refer to the specific calibration instructions provided with your buffer solutions or on the device itself for detailed steps. Generally, the process involves:

1. Prepare two standard pH buffer solutions, commonly pH 7.00 and either pH 4.00 or pH 10.00, depending on your expected measurement range.
2. Rinse the pH electrode with distilled water.
3. Immerse the electrode into the first buffer solution (e.g., pH 7.00).
4. Follow the meter's calibration mode instructions (usually involving pressing a CAL button and adjusting the reading to match the buffer value).
5. Rinsiwch yr electrod â dŵr distyll.
6. Immerse the electrode into the second buffer solution (e.g., pH 4.00 or pH 10.00).
7. Repeat the calibration adjustment for the second buffer.
8. Rinse the electrode again with distilled water after calibration.

Note: Buffer solutions are not typically included with the meter and must be purchased separately.

8.1. Electrode Care and Cleaning

• Always rinse the pH electrode with distilled or deionized water before and after each use.
• Store the electrode with its protective cap filled with a suitable storage solution (e.g., pH 4 buffer or electrode storage solution). Never store dry.
• If the electrode becomes dirty or readings are sluggish, clean it gently according to the electrode manufacturer's instructions. Avoid abrasive cleaning.

8.2. Storio

• When not in use, store the meter and probe in a cool, dry place, away from direct sunlight and extreme temperatures.
• Tynnwch y batris os na fydd y ddyfais yn cael ei defnyddio am gyfnod hir er mwyn atal gollyngiadau.
