available buffers and you can choose the one used.

Manual Selection

–

the desired pH buffer is manually selected from all available buffers, regardless of measured value.

To select the Buffer Entry Type:

• Use

or

to select the Calibration option.

• Press

and use

or

to highlight the

Buffer Entry Type option.

• Press

and use

or

to highlight the

desired option.

• Press

to confirm your selection or press

to

cancel operation.

1st Cal. Point

Two options are available for the 1st Cal.: Point and Offset.
If Point option is selected, the slope values adjacent to the calibration points will be reevaluated (normal calibration).
If at least a two-point calibration has been performed and an offset correction of the electrode is wanted
(maintaining the existing slope values), perform a one-point calibration using the Offset option.
To set the 1st Cal. Point:

• Use

or

to select the

Calibration option.

• Press

and use

or

to highlight the

1st Cal. Point option.

• Press

and use

or

to highlight the

desired option.

• Press

to confirm your selection or press

to

cancel operation.

Edit Custom Buffers

If you want to use other buffers than the ones already memorized (standard buffers), the Edit Custom Buffers option
is available, allowing you to set the desired pH buffers. Up to five pH custom buffers can be set.

Make sure the TDS factor has been set before taking TDS measurements (see

TDS Setup section).

DIRECT MEASUREMENT

To measure the TDS of a sample using the

Direct reading mode:

• Press

and then

to select TDS measure mode.

• Select the

Direct reading mode (see TDS Setup section).

• Proceed as for the conductivity measurement (see

Conductivity

Measurement section).

DIRECT/AUTOHOLD MEASUREMENT

To measure TDS of a sample using the

Direct / AutoHold reading mode:

• Select the

Direct / AutoHold reading mode (see TDS Setup

section).

• Proceed as for the conductivity measurement. (see

Conductiv-

ity Measurement section)
