Introduction Intended Use The Stratos Pro A4... MSPH is used for pH/mV, ORP, and temperature measurement in industry, environment, food processing, and sewage treatment. The sturdy molded enclosure can be fi xed into a control panel or mounted on a wall or at a post. The protective hood, which is avail- able as accessory, provides additional protection against direct weather exposure and mechanical damage.

Protective Wiring of Relay Contacts Protective Wiring of Relay Contacts Relay contacts are subject to electrical erosion. Especially with inductive and capacitive loads, the service life of the contacts will be reduced. For suppression of sparks and arcing, components such as RC combinations, nonlinear resistors, series resistors, and diodes should be used.

Confi guration Time and Date Control of the calibration and cleaning cycles is based on the time and date of the integrated real-time clock. In measuring mode the time is shown in the lower display. When using InduCon sensors, the calibration data is written in the sensor head.
Digital Sensors Operation Stratos Pro can be operated with three diff erent types of digital sensors (Memosens, InduCon). The following display examples refer to a transmitter and a digital pH sensor (slight variations for other combinations). The sensor type is selected during confi guration. The device only switches to measuring mode when the connected sensor corresponds to the type confi gured (Sensoface is happy): Otherwise, an error message is released.

Calibration Please note: • All calibration procedures must be performed by trained person- nel. Incorrectly set parameters may go unnoticed, but change the measuring properties. • The response time of the sensor and temperature probe is considerably reduced when the sensor is fi rst moved about in the buff er solution and then held still.
Selecting a Calibration Mode Calibration is used to adapt the device to the individual sensor characteristics, namely asymmetry potential and slope. Access to calibration can be protected with a passcode (SERVICE menu). First, you open the calibration menu and select the calibration mode: CAL_PH Depending on confi guation setting: AUTO...
Zero adjustment Zero Adjustment (ISFET) This adjustment allows the use of ISFET sensors with diff ering nominal zero (pH only). The function is available when Sensor selection = MEMOSENS has been set during confi guration. Zero adjustment is disabled for any other sensors. The adjustment is made using a zero buff er (pH 7.00).

-U1- Specifiable Buffer Set You can specify a buff er set with 2 buff er solutions in the temperature range of 0 ... 95 °C, step width: 5 °C. To do so, select buff er set -U1- in the confi guration menu. As delivered, the Ingold technical buff er solutions pH 4.01 / 7.00 are stored as buff er set and can be edited.

Sensoface (Sensocheck must have been activated during confi guration.) The smiley in the display (Sensoface) alerts to sensor problems ( defective sensor, sensor wear, defective cable, maintenance request). The permitted calibration ranges and the conditions for a friendly, neutral, or sad Sensoface are summarized in the following table. Additional icons refer to the error cause.

Sensoface Display Problem Status Asymmetry Asymmetry potential (zero) potential and and slope of the sensor are slope still okay. The sensor should be replaced soon. Asymmetry potential and slope of the sensor have reached values which no lon- ger ensure proper calibration. Replace sensor.
Page 138
Sensoface Display Problem Status Sensor wear High temperatures and pH (for digital values have caused a wear of sensors only) over 80%. The sensor should be replaced soon. Wear is at 100%. Replace sensor.
