Instruction Manual PCD 650

1. Rinse the electrode in clean water and prepare electrode for calibration.

2. Dip the probe in custom calibration buffer. The tip of the probe must be

completely immersed into the solution. Stir the probe gently to create a

homogeneous solution.

3. The screen shows 2 readings. The upper display shows the pH reading of

the solution with respect to previous calibration (if any) & lower display

shows the pH reading of the solution without any calibration. Use &

keys to adjust the upper display to the pH value of your custom buffer.

4. Press ENTER key to confirm the calibration.

5. Rinse the probe with clean water. Place it in the next buffer and follow the

steps 2, 3 and 4 to calibrate other points.

Function Keys available in pH Calibration mode:

TEMP (F1)

Goes to temperature calibration

CLR-C (F2)

Clears previous calibration (if any) after ENTER key is pressed for the

confirmation screen

NEXT (F3)

Shows calibration report

ESC (F4)

Exits from calibration and goes back to pH measurement mode

ENTER

Confirms the calibration

Increases/decreases pH buffer reading

(Not functional)

3.3.3 Calibration Report

Calibration report gives you detailed information on calibration. It includes date

& time, buffer group, offset, temperature, number of days calibration is over

due and slope information.

To View calibration Report:

1. From pH measurement mode, press left or right arrow key to navigate

to other available functions until you see REPO function in the LCD.

2. Press REPO (F2) key. The first page of calibration report is shown in the

display.

3. Press PAGE (F1) to view the second page of the report.

4. Press PRIN (F2) to transfer the calibration report to computer through IrDA.

(Refer page 37 to print data).

Note: If you wish to completely re-calibrate the meter, you need to clear

previous calibration data. Press CLR-C (F2) key to clear previous

calibration. The meter shows you confirmation screen. Press ENTER key
