5.1.1 Measuring the pH value
When connecting an earthed PC, measurements cannot be performed in
earthed media as the values would be incorrect.
The USB interface is not galvanically isolated.
To ensure the high measurement accuracy of the measuring system, always measure with a calibrated electrode (see section 5.2
C
ALIBRATION, page 25).
1. Connect the pH electrode to the meter.
2. If necessary, select the measured parameter with <M>.
3. When measuring without temperature sensor:
Temper the test sample or measure the current temperature and enter it
with <>
<>.

4. Immerse the pH electrode in the test sample.
The measured value is checked for stability (automatic stability control).
The display of the measured parameter flashes.
5. Wait for a stable measured value.
The display of the measured parameter no longer flashes.
The stability control function (AutoRead) continually checks the stability of the
measurement signal. The stability has a considerable impact on the reproducibility of measured values.
The measured parameter flashes on the display
as soon as the measured value is outside the stability range
when the automatic Stability control is switched off.
You can activate or switch off the automatic Stability control function (see
section 7.1.1 CHANGING THE SETTINGS FOR PH MEASUREMENTS, page 38).

2.
Using <ENTER>, activate the Stability control function manually.
The [AR] status indicator appears while the measured value is
assessed as not stable. A progress bar is displayed and the display of
the measured parameter flashes.
The [HOLD][AR] status indicator appears as soon as a stable measured value is recognized. The progress bar disappears and the display

5.1.2 Measuring the temperature
For reproducible pH and ORP measurements, it is essential to measure the
temperature of the test sample.
You have the following options to measure the temperature:
Automatic measurement of the temperature with the temperature sensor
(NTC 30 or Pt 1000) integrated in the sensor.
Measurement with an external temperature sensor.
Manual determination and input of the temperature.
The measuring instrument recognizes whether a suitable sensor is connected
and automatically switches on the temperature measurement.
The display of the temperature indicates the active temperature measuring
mode:
Temperature

Resolution of the
temp. display
Temp. measurement

ture sensor
- 1 °C Manual
If you wish to measure (or calibrate) without temperature sensor, proceed as
follows:
1. Measure the current temperature of the test sample.
2. Set the temperature value with <><>.
or
In the <F1>/[Menu]/Man. temperature menu, set the temperature value
with <><>.

5.2 Calibration
5.2.1 Why calibrate?
pH electrodes age. This changes the zero point (asymmetry) and slope of the
pH
electrode. As a result, an inexact measured value is displayed. Calibration
determines and stores the current values of the zero point and slope of the
electrode.
Thus, you should calibrate at regular intervals.
5.2.2 When do you have to calibrate?
After connecting a sensor
Routinely within the framework of the company quality assurance
When the calibration interval has expired
5.2.3 Automatic calibration (AutoCal)
Make sure that in the sensor menu, Buffer menu, the buffer set is correctly
selected (see
7.1.1 CHANGING THE SETTINGS FOR PH MEASUREMENTS, PAGE 38).
Use any one to five buffer solutions of the selected buffer set in ascending or
descending order.
Below, calibration with YSI buffers (YSI) is described. When other buffer sets
are used, other nominal buffer values are displayed. Apart from that, the proce
dure is identical.
If single-point calibration was set in the menu, the calibration procedure is automatically finished with the measurement of buffer solution 1 and the calibration record is displayed.
1. Connect the pH electrode to the meter.
2. Keep the buffer solutions ready.
When measuring without temperature sensor:
Temper the buffer solutions or measure the current temperature.
3. In the measured value display, select the measured parameter pH or mV
with <M>.

5.2.7 Continuous measurement control (CMC function)
The Continuous Measurement Control (CMC function) facilitates to evaluate
the current measured value instantly and definitely.
After each successful calibration the scale of the pH measuring range is
displayed in the measured value display. Here you can very clearly see
whether or not the current measured value is in the calibrated part of the
measuring range.
The following information is displayed:
1 Measuring range for which a valid calibration is available (white).
Measured values in this range are suitable for documentation.
2 Measuring range for which no valid calibration is available (shaded).
Measured values in this range are not suitable for documentation. If
necessary, calibrate the meter with buffers covering this measuring
range.
If the current measured value is outside the calibrated range, this
area is shaded stronger.
If a measured value is outside the measuring range pH 0 - 14, overflow arrows are displayed at the left or right edge of the measuring
range.

6.1.2 Measuring the temperature
For reproducible ORP measurements, it is essential to measure the temperature of the test sample.
You have the following options to measure the temperature:
Automatic measurement of the temperature by the temperature sensor
(NTC 30 or Pt 1000) integrated in electrode.
Measurement by an external temperature sensor.
Manual determination and input of the temperature.
The measuring instrument recognizes whether a suitable sensor is connected
and automatically switches on the temperature measurement.
The display of the temperature indicates the active temperature measuring
mode:
Temperature
sensor
Resolution of the
temp. display
Temp. measurement
yes 0.1 °C Automatic with temper-
ature sensor
- 1 °C Manual
If you wish to measure (or calibrate) without temperature sensor, proceed as
follows:
1. Measure the current temperature of the test sample.
2. Set the temperature value with <><>.
or
In the <F1>/[Menu]/Man. temperature menu, set the temperature value
with <><>.
6.2 ORP calibration
ORP electrodes are not calibrated. You can, however, check ORP
electrodes by measuring the ORP of a test solution and comparing
the value with the nominal value.

General information
Adjusting To manipulate a measuring system so that the relevant value (e. g. the
displayed value) differs as little as possible from the correct value or
a value that is regarded as correct, or that the difference remains
within the tolerance.
AutoRange Name of the automatic selection of the measuring range.
Calibration Comparing the value from a measuring system (e. g. the displayed
value) to the correct value or a value that is regarded as correct.
Often, this expression is also used when the measuring system is
adjusted at the same time (see adjusting).
Measured parameter The measured parameter is the physical dimension determined by
measuring, e. g. pH, conductivity or D.O. concentration.
