The Portavo 902 COND is a portable
conductivity meter. A plain-text line on
the high-contrast LCD screen makes
operation virtually self-explanatory.
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.
Overview of the Portavo 902 COND
Quiver
• Scratch-proof clear glass display, perfectly readable even after years
• Very long operating times with one set of batteries (4 x AA)
• 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.

8
Value-Added Features
Memosens
The Portavo 902 can communicate with
Memosens sensors. These digital sensors are auto-
matically 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 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 902 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.

10 Overview of the Portavo 902 COND
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 below:
Measuring

temperature)
Calibration
(Calibration by entry of cell constant)
Clock
(display of hours and minutes, seconds
and date)

12 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).
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.
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
Icon blinks Max. 10 operating hours remaining,
measurement is still possible
CAUTION! It is absolutely necessary to replace
the batteries.

13
Connecting a Sensor
The Portavo 902 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.
Separate temperature probe
Note: Temperature measurement using a separate temperature probe is only
possible 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 connecting cable is
connected to socket a(M8, 4 pins for Memosens sensors).
a b c d Connections
a - M8, 4 pins for Memosens sensors
b - Temperature probe GND
c - Temperature probe
d - DIN socket, 8 pins for analog sensors

14
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.
The following table gives you an overview.
Factory settings are shown in bold print.
This icon prompts you to select a menu item using the arrow keys –
the selection is conrmed by pressing set.

NOTICE!
• Make sure that the values of the calibration solutions used correspond exactly
to those specied in this manual.
If not, the resulting cell constant will be incorrect.
• When calibrating in a liquid, make sure that the sensor, the separate tempera-
ture probe (if present) and the calibration solution have the same temperature.
Only this ensures that the cell constant is determined correctly.

18
Measurement
In narrow installation conditions, the
conductivity measurement is inu-
enced by the sensor’s distance to the
wall and the wall material. This eect
can be compensated for by the instal-
lation factor. The transmitter corrects
the cell constant by multiplying it with
the installation factor. The value of
the installation factor depends on the
diameter and the conductivity of the
pipe as well as on the sensor’s distance
from the wall. If the distance from
the wall is sucient (>15 mm (0.59"),
DN80 or larger), it is not necessary to
consider the installation factor (1.00).
If the distance from the wall is smaller,
the installation factor increases (> 1)
when the pipe is electrically insulating
and decreases (<1) when the pipe is
electrically conductive. Refer to sensor
documentation if required.
Value blinks Use st to adjust the installation factor.
