Documentation

The Portavo 904(X) COND is a portable
conductivity meter. A plain-text line on the
high-contrast LCD screen makes operation
virtually self-explanatory. The device vari-
ant 904 X COND is available for applications
in hazardous locations up to Zone0.
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. Further-
more, 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.
Overview of the Portavo 904(X) COND
Quiver
• Scratch-proof clear glass display, perfectly readable even after years
• Very long operating times 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
(Li-ion battery not suited for Portavo 904 X COND for application in a hazardous
location)
• Data logger with 5000 values
• Micro USB port for communication with Paraly SW 112 software
for data evaluation of digital sensors (Memosens)
• Sensoface icons provide single-glance information on the sensor condition
(page 33)
• Real-time clock and indication of battery charging level
• At measuring temperatures from -20 to +100 °C the temperature detector can be
automatically identied.

Value-Added Features
Memosens
The Portavo 904 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 cal-
ibration 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 sen-
sor 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.
Overview of the Portavo 904(X) COND

10 Overview of the Portavo 904(X) COND
Protective Cover
The front of the meter is protected by a
cover, which can be completely ipped
over and secured to the back for oper-
ation. A label on the inner side of the
cover explains the control functions and
device messages.
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 com-
fortable and fatigue-free working at a lab
bench or desk.

Overview of the Portavo 904(X) COND
Display
The meter has a three-line display for
representing alphanumeric informa-
tion such as measurement and calibra-
tion 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
Inserting the Batteries
With four AA batteries, the Portavo has an
operating time of over 1000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.
Check the shipment for transport damage and completeness
(see Package Contents).
Caution!
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 by the manufacturer.
A special lithium-ion battery suited to the battery compartment is available for the
Portavo 904. The battery is recharged through the USB port.
Note: Not available for the Portavo 904 X (device variant for applications in hazard-
ous locations).
Precautions for application in hazardous locations
Warning!
• Only open the battery compartment of the Portavo 904 X 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.

14 Start-Up
Warning!
When using the Portavo 904 X (device variant for applications in
hazardous locations) in a hazardous location, 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 (see also Control Drawing
209.009-110).
Batteries
for Application in Hazardous Locations
Batteries (4x each) Temp. class Ambient temperature range
Duracell MN1500 T4 -10 °C ≤ Ta ≤ +40 °C
Energizer E91 T3 -10 °C ≤ Ta ≤ +50 °C
Power One 4106 T3 -10 °C ≤ Ta ≤ +50 °C
Panasonic Pro Power LR6 T3 -10 °C ≤ Ta ≤ +50 °C
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 Max. 10 operating hours remaining,
measurement is still possible
Caution! It is absolutely necessary to replace
the batteries.

Connecting a Sensor
The Portavo 904(X) COND 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 automatically recognizes a connected Memosens sensor and switches
accordingly. Memosens is signaled in the display.
Connections
a - Micro USB port
b - M8, 4 pins for Memosens sensors
c - Temperature probe GND
d - Temperature probe
e - DIN socket, 8 pins for analog sensors
Start-Up
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 for Memosens sensors).

16
Switching On the Meter
When you have connected the sensor, you can switch the meter on
by pressing the on/o or meas key.
When the meter is switched on with the on/o 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 meas 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 per-
formed as described on the following pages.

Conductivity Conguration
Prior to measurement, a conguration should be performed to match
the connected sensor and the desired measurement performance.
Furthermore, you can select the suitable calibration method.
