Before you begin: Hydrate electrode by immersing in electrode storage solution, pH 4 buffer or clean water for 30 minutes or
as needed. An "Or" reading often indicates the sensor is dry.
Buffer Set Selection: USA (pH 4.01, 7.00, 10.01) or NIST (pH 4.01, 6.86, 9.18).
1. Press and hold HOLD/ENT.
2. Press ON/OFF (while holding HOLD/ENT).
3. Release HOLD/ENT. Display shows USA or NIST.
4. Press CAL to select.
5. Press HOLD/ENT to confirm.
Calibration: up to 3 points using either USA or NIST buffer sets.
1. Press ON/OFF.
2. Dip electrode about 2 to 3 cm into the buffer.
3. Press CAL. 'CAL' indicator will appear. Upper display shows the reading based on last calibration, lower display shows the pH
buffer.
4. Wait for the reading to stabilize
5. Press HOLD/ENT to confirm. Lower display will show the next buffer.
6. Repeat steps 2, 4 and 5 with other buffers if necessary.
Note: Rinse electrode with clean water before dipping into next buffer.
Note: To abort calibration, press CAL.
Note: After 3 point calibration the meter returns to measurement mode. If only 1 or 2 points are calibrated the remaining points
can be skipped by pressing CAL.
Measurement:
1. Press ON/OFF.
2. Dip the electrode 2 to 3cm into the sample. Stir and let the reading stabilize.
HOLD Function: Freezes the display.
