followed.
-
CAUTION
indicates a possibly dangerous situation that can lead to
slight (reversible) injury if the safety instruction is not fol
lowed.
NOTE
indicates a possibly dangerous situation where goods might be damaged
if the actions mentioned are not taken.
2.1.2 Safety signs on the meter
Note all labels, information signs and safety symbols on the meter and in the
battery compartment. A warning symbol (triangle) without text refers to safety
information in this operating manual.
2.1.3 Further documents providing safety information

4.4.1 Changing the roll of paper (thermal paper)
1. Pull the lever (3) until the lid (4) of the paper compartment opens.
2. If necessary, remove any remains of the old roll of paper.
3. Insert the new roll of paper. The start of the paper should poke out of the
paper compartment.
4. Close the lid (4) of the paper compartment so that it clicks into place.
5. If necessary, move the printer paper forward with <FEED>.

5.4.6 Example 2 on navigation: Setting the date and time
The measuring instrument has a clock with a date function. The date and time
are shown in the measured value display.
When storing measured values and calibrating, the current date and time are
automatically stored as well.
The correct setting of the date and time and date format is important for the following functions and displays:
Current date and time
Calibration date
Identification of stored measured values.
Therefore, check the time at regular intervals.
After a fall of the supply voltage (empty batteries), the date and time
are reset.
The date format can be switched from the display of day, month, year
(dd.mm.yyyy) to the display of month, day, year (mm/dd/yyyy or mm.dd.yyyy).

Using <MENU/ENTER__>, open the Storage & config menu.
The instrument is in the setting mode.
2. Select and confirm the System / Clock menu with <><> and

6.1 Measuring
6.1.1 Measuring the pH value
NOTE
When connecting an earthed PC/printer, 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 6.2
CALIBRATION, page 31).
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.
<>.
Stability control
(AutoRead)
& HOLD function
The stability control function (AutoRead) continually checks the stability of the
measurement signal. The stability has a considerable impact on the reproduc
ibility 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 9.3.1 SYSTEM, page 75).

1. Freeze the measured value with <AR>.
The [HOLD] status indicator is displayed.
The HOLD function is active.
You can terminate the Stability control function and the HOLD func-
tion with <AR> or <M> at any time.
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 of the measured parameter stops flashing.
The current measurement data is output to the interface. Measurement
data meeting the stability control criterion is marked by AR.
Criteria for a stable
measured value
You can prematurely terminate the Stability control function manually with <ENTER> at any time. If the Stability control function is
prematurely terminated, the current measurement data are output
to the interface without the AutoRead info.
3. Using <ENTER>, start a further measurement with stability control.

6.1.2 Measuring the temperature
For reproducible pH 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
30 or Pt 1000) integrated in the sensor.
(NTC
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:

If you wish to measure (or calibrate) without temperature sensor, proceed as
follows:

2. Set the temperature value with <><>.
or
In the <MENU/ENTER>/pH/Man. temperature menu, set the tempera-
ture value with <><>.
