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.

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.

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.

pH measurement (display of measured value, temperature, date and time)

Oxygen calibration – step 1 (calibration in air)

Logger data for conductivity (display of measured value, memory location, temperature, date and time)

Oxygen calibration – step 2 (adjusting the relative humidity)

Clock (display of hours and minutes, seconds and date)

Overview

Keypad

The keys of the membrane keypad have a noticeable pressure point.

They have the following functions:

Switches the meter on and displays the device and calibration data

(see Start-up)

Switches the meter on / Activates measuring mode / Stops the data logger

Starts calibration

Activates conguration / Conrms entries

Displays time and date, allows setting the clock using set

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.

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.

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).

Start-Up

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).

Connections

a - Micro USB port b - M8, 4 pins, for Memosens lab cable c - Temperature probe – GND d - Temperature probe e - M12, 8 pins, for Memosens sensors

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.
