Quickstart

Measuring Mode

After the operating voltage has been connected, the analyzer auto-

matically goes to“Measuring“ mode. To call the measuring mode from

another operating mode (e.g. Diagnostics, Service):

Hold meas key depressed (> 2 s).

Sensoface indicator

(sensor status)

Time (or ow)

Mode indicator

(measuring)

Hold meas key

depressed for calling

the measuring mode

(pressing once more

switches the display)

Depending on the conguration, one of the following displays can be

set as standard display for the measuring mode (see page 6):

• Measured values channel A and channel B as well as time

(default setting)

Measured value and tag number (“TAG”)

• Conductivity and temperature of channel A (see example above)

• Conductivity and temperature of channel B

• Time and date

• Measured value channel A, channel B and ow

• Output currents

Note: By pressing the meas key in measuring mode

you can view the displays for approx. 60 sec.

You must congure the device for the respective measurement

task!

Sensocheck, Sensoface sensor monitoring

Sensocheck continuously monitors the sensor and its wiring.

Sensocheck is user-dened (default: O).

Sensoface provides information on the sensor condition.

The three Sensoface indicators provide information on

required maintenance of the sensor.

When Sensoface is“sad”, the display turns purple.

Pressing the info key shows an information text.

The MAIN DISPLAY is the display which

is shown in measuring mode. To call

the measuring mode from any other

mode, hold the meas key depressed

for at least 2 sec.

By pressing meas briey you can step

through further displays such as tag

number (TAG) or ow (L/h).

These displays are turquoise. After

60 sec they switch back to the main

display.

approx. 2 s

Press enter to select a display as

MAINDISPLAY.

The secondary display shows

“MAINDISPLAY – NO”.

Use the UP / DOWN arrows to select

“MAIN DISPLAY – YES”

and conrm by pressing enter.

The display color changes to

measuring mode.

Example:

Display of conductivity 1 and 2

and calculated pH value.

Conductivity 1

Conductivity 2
