Warranty
Defects occurring within 3 years from delivery date shall be remedied free of charge
at our plant (carriage and insurance paid by sender).
Sensors and accessories: 1 year
Subject to change
Return of products under warranty
Please contact our Service Team before returning a defective device.
Ship the cleaned device to the address you have been given.
If the device has been in contact with process uids, it must be decontaminated/
disinfected before shipment. In that case, please attach a corresponding certicate,
for the health and safety of our service personnel.

The following names are registered trademarks. For practical reasons they are shown
without trademark symbol in this manual.

Disposal
Please observe the applicable local or national regulations concerning
the disposal of“waste electrical and electronic equipment”.

4Start-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 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.

Start-Up
Connecting a Sensor
The Portavo 902 PH provides several connections so that many types of sensors
can be used for measurement. 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
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 Connections
a - M8, 4 pins for Memosens sensors
b - Temperature probe GND
c - Temperature probe
d - pH socket (DIN 19 262)
Caution!
Always make sure that a sensor is connected to the meter before
starting measurement.
Explanation: The analog pH input of the Portavo is an electrometer
amplier with an extremely high-impedance. When the sensor is not
in contact with the medium or not connected to the meter, electric
charges on the input can generate arbitrary, stable pH or mV values
which will be shown in the display.
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).

6
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
performed as described on the following pages.

pH 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.

Error Codes and Device Messages
Error messages are indicated as “ERROR …” on the display. Information on the sensor
condition is indicated by the“Sensoface” icon (friendly, neutral, sad) possibly accom-
panied by an info message (“INFO …”).
Sensoface (the“smiley”icon) provides
information on the sensor condition (main-
tenance request). Measurement can still be
performed. After a calibration, the corre-
sponding Sensoface icon (friendly, neutral,
sad) is shown together with the calibration
data. Otherwise, Sensoface is only visible in
measuring mode.
The most important error messages and
“Sensoface” info messages are shown on the
inside of the protective cover.
A complete list of messages and their mean-
ings is provided in the following tables.
Example of a“Sensoface”message:
INFO 1 (cal timer expired)
Example of an error message:
ERROR 8 (identical calibration media)
