8 Calibration

8.2

pH antimony electrode

Antimony electrodes are calibrated in the same way as normal pH ones.

- General notes on calibration, see “General”, page 68.

- 1-point calibration, see Chapter 8.1.1 “1-point calibration”, page 68.

- 2-point calibration, see Chapter 8.1.2 “2-point calibration”, page 70.

- 3-point calibration, see Chapter 8.1.3 “3-point calibration”, page 72.

8.3

ORP electrode

General

Two calibration options are available to adapt the instrument to the ORP
electrode.

- 1-point calibration

With configuration “mV” for the UNIT.

- 2-point calibration

With configuration “%” or “CUSTOMIZED” for the UNIT.

When to
calibrate

The ORP combination electrode (or metal and reference electrode) should be
cleaned at regular intervals (depending on the sample medium) and the
transmitter calibrated.

Calibration
start

Calibrating can be started as follows:

- by pressing the

key,

if this has been enabled in ADMIN. LEVEL / PASSWORD / CALIB. ENABLE.

- via ADMIN. LEVEL / PASSWORD / CALIB. LEVEL

- via CALIB. LEVEL

if this has been enabled in ADMIN. LEVEL / PASSWORD / CALIB. ENABLE.

8.3.1

1-point calibration

Requirements

- The supply voltage for the instrument must be present.

see Chapter 4 “Electrical connection”, page 12ff.

- A combination electrode must be connected to the transmitter.

- “REDOX” (ORP) must be configured for the sensor and “mV” for the UNIT.

The display blinks during calibration.

The analog outputs will respond as configured in OPERATOR
LEVEL / ANALOG OUTPUT x / DURING CALIBRATION.

The relays will respond in accordance with the configuration of the
analog outputs and switching outputs.
