The Liquiline To Go CYM290 is a portable
multiparameter meter for use with analog
or digital sensors. The meter automatically
recognizes a connected Memosens sensor
and accordingly selects the correspond­ing process variable. By simply replacing
the Memosens sensor, the meter can be
used for measuring conductivity, pH or
oxygen.
Operation is simple and intuitive, support­ed by detailed information and help texts.

Quiver

The meter stands out by the following features:

• 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

• Long operating time with one set of batteries (4 x AA) or use of a Li-ion battery for
reliable operation even at high or very low operating temperatures

• Data logger with 10,000 values

• Micro USB port

• Sensoface icons provide single-glance information on the sensor condition

• Real-time clock and indication of battery charging level

• Automatic compensation of ambient pressure for oxygen measurement

• At measuring temperatures from -20 to +100 °C the temperature detector can be
automatically identied.

Overview

Overview

Value-Added Features

Memosens

The Liquiline To Go CYM290 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, a status 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.

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.

Start-Up

Inserting the Batteries

With four AA batteries, the CYM290 has an
operating time of up to 500 h when oper­ated in logger mode (see page 36).
Open the battery compartment on the
rear of the device. Be sure to observe the
correct polarity when inserting the batter­ies (see markings in the battery chamber).
Close the battery compartment cover and
screw it handtight.

A special lithium-ion battery suited to the battery compartment is available for the
Liquiline To Go CYM290. The battery is recharged through the USB port.

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.

Connecting a Sensor

The Liquiline To Go CYM290 provides a pH socket acc. to DIN 19262 for analog pH
sensors. Alternatively, you can connect a Memosens sensor for pH, conductivity or
oxygen measurement. The meter automatically recognizes a connected Memosens
sensor and accordingly selects the corresponding process variable.
Memosens is signaled in the display.
Note that only one sensor may be connected to the meter at a time.

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 e

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 (Memosens lab cable) or e.

Connections

a - Micro USB port
b - M8, 4 pins, for Memosens lab cable
c - Temperature probe GND
d - Temperature probe
e - pH socket acc. to DIN 19262 for analog

sensors

14

Switching On the Meter

You can use or to switch the meter on:

• With , the meter immediately switches to measuring mode.

• With , rst a self test is performed and then the calibration data
and settings are displayed before the meter switches to measur­ing mode.

pH Oxy

Sensor Network Diagram (pH and Oxy only)

Provide single-glance information on the following parameters of the connected
sensor:

• Slope

• Zero point (operating point for Memosens ISFET)

• Sensocheck (pH) or leakage current (ISFET and Oxy)

• Response time

• Calibration timer

• Wear (Memosens)
Parameters which cannot be checked are shown as inactive (gray) and are set to
100% (e.g., Sensocheck for analog sensors).

The parameter values should lie between the outer (100%) and inner (50%) hexa­gon. When a value enters the inner hexagon (<50%), the corresponding caption text
ashes red (see example).
