9 Calibration

9.1 General information

The zero point (intercept) and slope of pH sensors stray from copy to copy. During the service life of the sensor, up to the time it must be replaced by a new sensor, the zero point and slope change. To allow for precise measurements, the transmitter must be adjusted

(calibrated) to the current sensor parameters. The calibration is performed using buffer solutions.

Only the zero point needs to be calibrated for redox sensors.

9.1.1 When is calibration required?

The electrochemical sensors should be cleaned and the transmitter should be calibrated at regular intervals (depending on the measuring medium)!

With the correct wiring of device and sensor, and correct configuration of the device, a measurement without calibration should be possible.

If this is not the case, influencing factors such as short circuit, open circuit, EMC and flow conditions should also be considered.

9.2 Activating and starting calibration mode

During the calibration process, the display flashes.

The analog outputs respond as they were calibrated on the USER LEVEL / ANALOG OUTPUT x /

FOR CALIBRATION.

The response of the relay depends on the configuration of the switching output!

40

Calibration can be cancelled at any time with the EXIT key. Old calibration data will not be lost.

Calibration is performed using the instrument keys.

The zero point and slope of a sensor can also be entered manually. This should only be done in exceptional cases. Some sensors come with a test report that specifies the zero point and slope. These values simply provided documentation that the sensor was in proper condition upon delivery. Since these values change during storage, they are not suitable for manual entry. We always advise performing calibration with buffer solutions.

The timeout function is not active during calibration!

9.2.1 Starting calibration from the calibration level «CALIB»

Use the menu to switch to the calibration level (see

Section 7.4 «Selecting levels», page 20 and Section

7.8 «Calibration level (CALIB)», page 24).

✱

P

Press and hold (for more than 2 sec) / then select CALIB.

✱

P

Press and hold (for less than 1 sec) / then enter code 110.

✱ Confirm with

P

,

continue with Section 9.4 «One-point or two-point calibration», page 43.

9.2.2 Starting calibration with the hot key (rapid access)

Activation of the calibration mode by rapid access must be previously enabled:

P

> Press and hold for 2 seconds / Set ADMIN / CAL /

CA.LVL to 1.

✱ Press the

P

and keys,

continue with Section 9.4 «One-point or two-point calibration», page 43.

41

9.3 Canceling calibration and error messages

Calibration can be cancelled at any time with the EXIT key. Old calibration data will not be lost.

During the calibration process, the transmitter calculates the electrode parameters zero point and if applicable slope. If the calculated values fall outside the permissible parameter limits, an error message is generated.

For the permitted value ranges of parameters NULL and SLOPE see

Section 8.1.1 «Measurement input — main value (submenu «PH»)», page 26.

9.3.1 Zero point error

Parameter limits for NULL have been violated.

9.3.2 Slope error

Parameter limits for SLOPE have been violated.

9.3.3 General error during calibration

42

The parameter limits for NULL and SLOPE have been violated and/ or the two calibration points Ref.1 and Ref.2 are too close to each other.

For two-point calibration of a pH sensor, the minimum spacing is

2 pH.

For two-point calibration of a redox sensor, the minimum spacing is

2 mV.

The greater the spacing, the more accurate the calibration.

9.3.4 Acknowledging errors

✱ Press the

P

keys or EXIT.

The error message is deleted.

The faulty parameters NULL and/or SLOPE are not saved.

The instrument continues working with old calibration data.

9.3.5 Additional measures

✱ Check the quality and condition (age) of the buffer solutions.

✱ Check whether the sensor is dirty or needs to be replaced.

✱ Check whether the sensor plug is moist or the wiring is faulty.

✱ Observe the minimum spacings for buffer or reference values.

9.4 One-point or two-point calibration

For one-point calibration, the transmitter is only adjusted to the zero point of the sensor.

In two-point calibration the transmitter is adjusted to both the zero point of the sensor and its slope. We expressly recommend twopoint calibration!

9.4.1 Selecting one-point calibration

Select CAL I-PT.

For more details see Section 9.5.1 «One-point calibration (zero point)», page 44.

11.3 Manual mode of the relay output

For test purposes or when starting up systems, a constant signal can be generated by the transmitter.

Manual mode can be set with parameter: USER / BIN.1 / SIM.1 to

0

1

2

= inactive

= active => LED «K1» is lit

= No manual mode.

Indication of manual mode

About 3

If one of the outputs is in manual mode, this is indicated in the change to process value display by an «S» or «-«.

S The relevant output is in manual mode.

The relevant output is not in manual mode.

1 2 3

1st place Analog output — pH/redox voltage

2nd place Analog output — temperature

3rd place Binary output 1

In the example above, the analog temperature output is in manual mode. No other outputs are in manual mode.

When the user exits manual mode, the output signal immediately assumes the value proportional to the pH value/redox voltage or the temperature process value.

57

After «Supply voltage On» manual mode is always deactivated.

11.4 Behavior of the relay during calibration

The behavior of the relay with the parameter:

USER / BIN.1 / CAL.1 set to

0 = Relay inactive

1 = Relay active

2 = Relay unchanged

(during calibration the relay status remains set to the status that was valid before the calibration process)

11.5 Pulse function of the relay output

The limit comparator is reset after an adjustable «pulse time.» The parameter for this is: USER / BIN.1 / T.PUL1 .

It can be set from 0 = 0 seconds (no pulse function) to 999 = 999 seconds.

LED «K1» is lit red as long as the switching condition is met.

No OFF delay is possible in pulse mode.

2 = Relay unchanged
