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.

2 Installation, Connection and Commissioning

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.
