Care and Use

Open Air Calibration Procedure

1. Remove the membrane

Detach the membrane from the probe and dry the diode thoroughly.

2. Zero out the display

Connect the probe, power on the meter, and ensure the display reads 0.0. If needed, use the supplied screwdriver to adjust the “0” screw until 0.0 is shown.

3. Fill the membrane

Place the “O” ring inside the membrane at the thread base. Fill with MA9071 electrolyte solution, just below the o-ring, ensuring no bubbles are present.

4. Attach the membrane

Screw the membrane onto the probe securely.

5. Let stabilize

Hang the probe facing downward from a table and allow the display to stabilize, which may take 5 to 15 minutes.

6. Adjust

Press and hold the “Cal” button and use the screwdriver on the front Cal position “100%” to set the display to 100.

The meter is now calibrated.

Extra tips

• Replace membranes if you notice wrinkles or stretch marks.
• Always use fresh MA9071 electrolyte solution for calibration.
