Hold function: “freezes” the outputs

The current output is “frozen” in the setup
mode and during calibration, i.e. the last
current value is constantly output. The display
shows the “HOLD” message (see chapter 5.8,
page 46 for hold settings).

Note:

•

During automatic operation, all
contacts will go to their normal
positions.

• All hold settings are ignored for

Chemoclean, timer and the external hold
function, i.e. hold is always activated for
these functions.

• Any alarm delay accumulated will be reset

to ‘0’.

• This function can also be activated

externally via the hold input (see
connection diagram in Fig. 3.10; digital
input 1).

• The manual hold (field S3) remains active

even after a power failure.

4.6

Access codes

All instrument access codes are fixed, i.e.
they cannot be modified. Three access codes
are distinguished (cf. Fig. 4.3):

• Any code: Read mode access, i.e. all

settings can be viewed but not modified
(access with ENTER/CAL key, see Fig. 4.3).

• Code 22: Access to calibration and offset

menus (access with CAL key, see Fig. 4.3).

• Code 22: Access to configuration menus

for instrument configuration and user
settings (access with ENTER key, see
Fig. 4.3).

• See chapter 4.3, page 17 for hardware

locking and unlocking.

4.7

Display during measurement

The measurement display can be individually
adapted to user requirements.

Settings accessed with PLUS key:

• Press the PLUS key to display the

temperature in °F instead of °C.

• Press the PLUS key a second time to

suppress the temperature display.

• Press the PLUS key a third time to display

the uncompensated conductivity value.

• Press the PLUS key a fourth time to return

to the standard display.

Settings accessed with MINUS key:

• Press the MINUS key to display the first

error message.

• Press the MINUS key repeatedly to display

the following error messages (up to ten).
If no further errors exist, the display returns
to the measuring mode.

Note:

Function group F (alarm, see
chapter 5.4.1) can be used to define
an alarm for each individual error
code.

4.8

Calibration

Please refer to chapter 5.11 for the calibration
procedure.
