Overview

The Liquiline To Go Ex CYM291 is

a portable multiparameter meter for
measuring pH, ORP, conductivity
or oxygen. With a plain text line on a
high-contrast LCD, operation is largely
intuitive.

Quiver

The meter stands out by the following features:

• Application in hazardous locations up to Zone 0

• Use of digital Memosens sensors

• A detachable quiver protects the sensor and prevents it from drying out.
Furthermore, it can be used for calibration.

• The rugged housing is made of a high-performance polymer. It provides high
impact resistance and dimensional stability even when exposed to extreme
moisture.

• Scratch-proof clear glass display, perfectly readable even after years

• Very long operating time with one set of batteries (4 x AA) for reliable operation
even at high or very low operating temperatures

• Data logger with 5000 values

• Micro USB port

• Sensoface icons provide single-glance information on the sensor condition
(page9)

• Real-time clock and indication of battery charging level

Overview

Value-Added Features

Memosens

The Liquiline To Go Ex CYM291 can communicate
with Memosens sensors. These digital sensors are
automatically identied and the meter switches to
the appropriate measurement method.
When a Memosens sensor is connected to the
meter, it is indicated by the logo shown on the
right. Furthermore, Memosens allows the storage
of calibration data, which will be available and
can still be used when the sensor is connected to
another Memosens-capable device.

Sensoface

Sensoface provides quick information on the
sensor condition. The three “smiley” faces as shown
on the right represent the sensor condition during
measurement and after a calibration. When the
condition deteriorates, an “INFO …” message gives
a hint to the cause.

9

Programmed buers

“Programmed buers” is a very convenient method
for pH calibration with automatic buer recogni­tion. You only have to select the buer set with the
buers used. The buers can then be used in any
order.

10

Overview

Protective Cover

The front of the meter is protected
by a cover, which can be completely
ipped over and secured to the back for
operation.

Hook

A fold-out hook on the back allows
suspending the meter. This leaves your
hands free for the actual measurement.
The rating plate is located beneath the
hook.

Protective Cover and Hook
Combined

Cover and hook can be joined together
to form a benchtop stand allowing com­fortable and fatigue-free working at a lab
bench or desk.

Overview

Display

The meter has a three-line display for
representing alphanumeric informa­tion such as measurement and calibra­tion data, temperatures and date/time.
Additional information is provided by
means of icons (Sensoface, battery
icon, etc.).
Some typical displays are shown here.

Start-Up

Check the shipment for transport damage and completeness (see Package
Contents).

NOTICE!

Do not operate the device when one of the following conditions applies:

• the device shows visible damage

• the device fails to perform the intended function

• prolonged storage at temperatures above 70 °C

• severe transport stresses
In this case, a professional routine test must be performed.
This test should be carried out at our factory.

Precautions for application in hazardous locations

WARNING!

• Only open the battery compartment of the Liquiline To Go Ex CYM291
outside the hazardous location.

• Never try to open the device. If a repair should be required, return the
device to our factory.

• Never use the USB port within the hazardous location.

13

Inserting the Batteries

With four AA batteries, the Liquiline ToGo
Ex CYM291 has an operating time of
approx. 500h.
Open the battery compartment on the
rear of the device. Be sure to observe the
correct polarity when inserting the batter‑
ies (see markings in the battery chamber).
Close the battery compartment cover and
screw it handtight.

14

A battery icon in the display indicates the battery power level:

Icon fully lled Batteries at full capacity

Icon partially lled Battery capacity is sucient

Icon empty Battery capacity not sucient;

calibration is possible, no logging

Icon blinks Only a few operating hours remaining,

measurement is still possible
NOTICE! It is absolutely necessary to replace
the batteries.

WARNING!

When operating the Liquiline To Go Ex CYM291 in a hazardous loca‑
tion, only the battery types listed below may be used. The batteries
must be from the same manufacturer and of identical type and
capacity. Never use new and used batteries together (“Certicates”,
Control Drawing 209.009‑150).

Connecting a Sensor

The Liquiline To Go Ex CYM291 provides several connections so that many types of
sensors can be used for measurement (see illustration below). Note that only one
sensor may be connected to the meter at a time. The meter recognizes the connect­ed Memosens sensor and displays the Memosens logo.

Separate temperature probe

After power-on, a separate temperature probe is automatically recognized. When
you want to replace the temperature probe, you must switch o the meter and then
switch it on again.

a b c d

Memosens sensors have a cable coupling, which allows convenient replacement
of sensors while the cable remains connected to the meter. The connecting cable is
connected to socket b (M8, 4 pins) or e (M12, 8 pins).

e

Connections

a - Micro USB port
b - M8, 4 pins, for Memosens lab cable
c - Temperature probe – GND

16

Switching On the Meter

When you have connected the sensor, you can switch the meter on
by pressing the or key.
When the meter is switched on with the key, rst a self test is
performed and then the calibration data and settings are displayed
before the meter switches to measuring mode.
When the meter is switched on with the key, it immediately
switches to measuring mode.
Depending on the connected sensor and the specic measur­ing task, several steps for conguration and calibration must be
performed as described on the following pages.

Data Logger

The meter provides a data logger. Prior to use, it must be congured and then
activated. You can choose from the following logger types:

• DIFF (signal-controlled logging of measured variable and temperature)

• INT (time-controlled logging at a xed interval)

• DIFF+INT (combined time- and signal-controlled logging)

• SHOT (manual logging by pressing the key)

The data logger records up to 5000 entries and saves them in a circular buer.
Already existing entries will be overwritten.
The following data are recorded: primary value, temperature, time stamp and device
status.

Error messages are indicated as “ERROR …” on the display. Information on the sensor
condition is indicated by the “Sensoface” icon (friendly, neutral, sad) possibly accom­panied by an info message (“INFO …”).

Example of an error message:
ERROR 1 (value out of range)

Sensoface (the “smiley” icon) provides
information on the sensor condition (main­tenance request). Measurement can still be
performed. After a calibration, the corre­sponding Sensoface icon (friendly, neutral,
sad) is shown together with the calibration
data. Otherwise, Sensoface is only visible in
measuring mode.

The most important error messages and
“Sensoface” info messages are shown on
the inside of the protective cover.
A complete list of messages and their
meanings is provided in the following
