Temperature probe adjustment
The Stratos can be adjusted to a connected temperature probe.
This is particularly useful for Pt 100 temperature probes.
(See Pg. 32)
This function should only be used by experts. Incorrectly set parameters may go unnoticed,
but change the measuring properties.

Safety Precautions
Be sure to read and observe the following requirements!
Never use the Stratos 2201/2211 pH for measurement in areas that are subject to an explo-
sion hazard during operation.
Be sure that the supply voltage does not exceed 30 Vdc.
Stratos 2201/2211 X pH is approved for operation in hazardous locations.
Before connecting the Transmitter to a power supply unit, make sure that this is an associ-
ated apparatus.
Whenever it is likely that the protection has been impaired, the instrument shall be made inoperative and
secured against unintended operation.
The protection is likely to be impaired if, for example:
the instrument shows visible damage
the instrument fails to perform the intended measurements
after prolonged storage at temperatures above 70 °C
after severe transport stresses
Before recommissioning the instrument, a professional routine test in accordance with EN 61010-1 must be
performed. This test should be carried out at our factory.
The instrument shall not be used in a manner not specified by this manual.

Proper Use
Stratos 2201/2211 (X) pH is used for pH and temper-
ature measurement in industry, the environment,
food processing and waste-water field. It can be
either field-mounted or fixed into a control panel.
Never use the Stratos
2201/2211 pH for measurement in
areas that are subject to an explo-
sion hazard during operation.
Stratos 2201/2211 X pH is ap-
proved for operation in hazardous
locations.

Installation and Commissioning
Installation and commissioning of
the Stratos may only be carried out
in accordance with this instruction
manual and per applicable local
and national codes. Be sure to ob-
serve the technical specifications
and input ratings.
Before connecting the Stratos
2201/2211 pH to a power supply
unit, make sure that this is not ca-
pable of outputting more than
30 Vdc.
Do not use alternating current or
mains power supply!
Stratos 2201/2211 X pH may only
be connected to an explosion-proof
power supply unit (for input ratings
refer to annex of Certificate of Con-
formity).
When commissioning, a complete
configuration must be carried out.
For easier installation, the terminal strips are of a
plug-in design. The terminals are suitable for single
wires and flexible leads up to 2.5 mm2 (AWG 14)
(see Pg. 11).
See Pg. 14 and following for connection examples.
Do not use cable clamp (shield) for
reference electrode connection
when auxiliary electrode (solution
ground) is in use.
