pH Setup

■

Setup

This section describes the setups in LAQUA 2000 series benchtop meters.

● P1 pH Setup

Using pH setup you can:

• Set pH buffer group

• Set pH resolution

• Set calibration alarm

• Erase calibration data

To set the pH function of PH2000, ION2000, or PC2000 meter, follow the procedure detailed

below:

Prerequisites

• Switch on the meter.

• Ensure that the meter is in pH measurement mode.

• Default pH buffer group in buffer setup is

USA

. You can change it to

NIST

NIST2

DIN

, or

CUST

(Custom)

if required.

• Erasing previous calibration data is recommended for accurate calibration. Default

calibration clear setup is

but to erase the calibration data, change the setup to

YES

To return to the measurement mode, press the

key.

pH Buffer Group

pH Buffer Values (

25°C)

USA

1.68, 4.01, 7.00, 10.01, 12.45

NIST

1.68, 4.01, 6.86, 9.18, 12.45

NIST2

1.68, 4.01, 6.86, 10.01, 12.45

DIN

1.09, 3.06, 4.65, 6.79, 9.23, 12.75

CUST

Use up to 6 pH buffers that are 1.0 pH

apart for manual calibration
