The Portavo 904 X MULTI portable multi-
parameter meter for measuring pH, ORP,
conductivity or oxygen. A plain-text line on
the high-contrast LCD screen makes oper-
ation virtually self-explanatory. 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. 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 MULTI
Quiver
• 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 for communication with Paraly SW 112 software for data evalua-
tion of digital sensors (Memosens)
• Sensoface icons provide single-glance information on the sensor condition
(page59)
• Real-time clock and indication of battery charging level

Value-Added Features
Memosens
The Portavo 904 X MULTI 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. Further-
more, Memosens allows the storage of calibra-
tion 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.
Automatic calibration with Calimatic (pH)
Calimatic 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.
As delivered, this calibration method is preset. It
can be adjusted or disabled in the conguration
menu.
Overview of the Portavo 904 X MULTI

10
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 MULTI

11
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.
pH measurement

ture, date and time)
Oxygen calibration – step 1

location, temperature, date and time)

Start-Up
Inserting the Batteries
With four AA batteries, the Portavo 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.
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 / +158 °F
• 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 Portavo 904 X MULTI
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 MULTI 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 Only a few operating hours remaining,
measurement is still possible
NOTICE! It is absolutely necessary to replace
the batteries.

15
Connecting a Sensor
The Portavo 904 X MULTI 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
Note: Temperature measurement using a separate temperature probe is only possi-
ble when no Memosens sensor is connected.
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.
Start-Up
Memosens sensors have a cable coupling, which allows convenient replacement
of sensors while the cable remains connected to the meter. The Memosens 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 cable
c - Temperature probe GND
d - Temperature probe
e - M12, 8 pins, for Memosens cable
a b c d e
WARNING! Explosion Hazard
NEVER use digital Memosens sensors without Ex approval in a hazardous
location! For these applications, you must use Memosens sensors with Ex approval.
These sensors, as well as the hazardous-area cables, are marked by an orange-red
ring.

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.
