Important notes:

ENGLISH

• The si627 P does not require ground connection (terminal 1).

• In environments with interference problems it is recommended to connect the instrument to ground in terminal 1.

It is also recommended to use shielding cable,

both for the electrode signal (triaxial cable) and the temperature probe.

The external shield of the triaxial cable and the

probe cable must be connected to terminal 10.

• If the temperature probe has a 2-wire cable instead of a 4-wire, fit a jumper between ter-

minals 6 and 7 and another one between 8 and 9, as indicated in the scheme.

4.7. Calibration of pH electrode

To measure pH correctly, the electrode and instrument set

MEASURE

pH 7.34 25.2 °C

needs to be calibrated regularly with buffer solutions. The instrument is capable of one-, two- and three-point calibration. The calibration parameters are stored in the memory until a new calibration is performed.

CODE 000

If an anomaly occurs during calibration an error message will appear on-screen (see page 19).

One-point calibration

CALIBRATE

This form of calibration is acceptable when pH values around that of the buffer used are being measured. One-point calibration only corrects the asymmetry potential of the electrode.

INSERT 1 st BUFFER 25°C

Two-point calibration

This is the most common type of calibration. We recommend pH 7 for the first buffer, and pH 4 or 9 for the second, depending on whether you will be working in the acid or

CALIBRATING

pH 7.02 19°C alkaline region. In addition to asymmetry potential, calibration with two buffers also compensates the electrode slope or sensitivity loss.

INSERT 2 nd BUFFER

Three-point calibration

This type of calibration is recommended when measurements are made across the entire pH scale. It is also used when a great deal of accuracy is required in a certain region.

CALIBRATING

pH 4.00 19°C For the first point pH 7 is recommended. For the second and

third points, two of the remaining values must be chosen (pH

4.9. Measurement

pH and temperature measurement

The pH value and the temperature in °C appear simultaneously on the display. The instrument is usually measuring pH (see page 13). The temperature is measured when an A.T.C. Pt 1000 is connected. Otherwise, it is necessary to inform the instrument about the temperature of the measured solution using the keys

ENGLISH

ORP (redox) measurement. mV range

To measure redox potential the instrument must be programmed to measure mV (see page 14). The temperature is measured when an A.T.C. Pt 1000 is connected. The redox potential (mV) of the solutions is affected by temperature. Nevertheless the instrument does not carry out any compensation. Hence it is impossible to introduce the process temperature manually.

5.1. Clean the measuring instrument and accessories

Important note: Never use cleaning such as turpentine, acetone or similar products to clean the instrument including the display and accessories. Only clean the housing and accessories using a soft, damp cloth. Mild soap solution may also be used. Dry the cleaned parts carefully with a soft cotton cloth.

8. Warranty and liability

The manufacturer warrants that the product supplied is free of material and manufacturing defects and undertakes the obligation to repair or replace any defective parts at zero cost.

The warranty period for instruments is 24 months. If a service contract is taken out within 6 months of purchase, the warranty period is extended to 60 months.

With the exclusion of the further claims, the supplier is liable for defects including the lack of assured properties as follows: all those parts that, within the warranty period calculated from the day of the transfer of risk, can be demonstrated to have become unusable or that can only be used with significant limitations due to a situation present prior to the transfer of risk, in particular due to incorrect design, poor materials or inadequate finish will be improved or replaced, at the supplier’s discretion. The identification of such defects must be notified to the supplier in writing without delay, however at the latest 7 days after the identification of the fault. If the customer fails to notify the supplier, the product is considered approved despite the defect. Further liability for any direct or indirect damages is not accepted.

If instrument-specific maintenance and servicing work defined by the supplier is to be performed within the warranty period by the customer (maintenance) or by the supplier (servicing) and these requirements are not met, claims for damages due to the failure to comply with the requirements are rendered void.

Any further claims, in particular claims for consequential damages cannot be made.

Consumables and damage caused by improper handling, poor installation or incorrect use are excluded from this clause.

The manufacturer process instruments are of proven reliability in many applications and are therefore often used in automatic control loops to provide the most economical possible operation of the related process.

To avoid or limit consequential damage, it is therefore recommended to design the control loop such that a malfunction in an instrument results in an automatic change over to the backup control system; this is the safest operating state for the environment and the process.
