OVERVIEW

The compact USB-powered fiber-optic meter FireSting®-PRO with 1, 2, or 4 channels for multiple analytes and sensor heads features:

• freely configurable channels for O2, pH and temperature
• broad optical sensor portfolio (multiple fiber-based and contactless sensor heads for several ranges)
• with (ultra-)high speed sampling
• zero-noise and zero-latency temperature compensation
• improved ambient light suppression and
• smart measuring modes for prolonged sensor lifetime
• pH, oxygen and temperature determination simultaneously in one sample

This single-device solution for multi-analyte measurements has integrated atmospheric pressure and humidity sensors for precise and easy oxygen sensor calibration, but also for automatic pressure compensation of the oxygen measurements. Furthermore, the FireSting®-PRO offers 4 analog outputs and a broadcast-mode.
The new innovative and user-friendly Pyro Workbench allows operation of several FireSting®-PRO meters in parallel as a scalable multi-channel system.

INTRODUCTION

The FireSting®-PRO comes with 1, 2, or 4 channels (optical sensor ST- connectors 1 to 4) for up to 4 fiber-optic sensors and one connector (T) for an external Pt100 temperature probe. The optical channel connectors are color coded, indicating the analyte (oxygen, (pre-calibrated) pH or temperature), which is currently measured and can be changed for each channel. The air inlet equilibrates the internal temperature, pressure and humidity sensors with the surrounding. Avoid covering these holes to ensure free  air circulation towards the internal sensors.

The micro-USB connector on the left side panel provides energy supply and data exchange with the PC. Right-hand side of it, a connector X1 for power and digital interface (7-pins) and a connector X2 for analog output (5 pins) is located.

QUICK START

Step 1: Download the correct software and manual from the downloads tab of your purchased device on www.pyroscience.com
Step 2: Connect the FireSting®-PRO meter with the micro-USB cable to the Windows PC/laptop (Windows 7, 8, 10).
Step 3: Connect appropriate PyroScience sensor(s) to the optical sensor connectors 1 to 4 at the device (see 4).
Step 4: Connect an external temperature sensor (item no. TDIP15 or TSUB21) to the Pt100 connector or, alternatively, an optical temperature sensor (see 5) to one of the optical sensor connectors 1 to 4 for automatic temperature compensation.
Step 5: Prepare appropriate calibration standards, as described in the respective sensor manuals (see 8).
Step 6: Start the logger software by clicking on the short-cut “Pyro Workbench” on your desktop.
Step 7: Open the Settings Wizard by clicking on the FireSting®-PRO picture. Select the respective analyte and enter all sensor settings for each sensor, including an appropriate mode of temperature compensation.
Step 8: Open the Calibration Wizard and follow the calibration instructions for each sensor. Measurements with the respective sensors will start automatically after all required sensor calibrations have been performed.
Step 9: Configure the Graphs according to your preferences.
Step 10: Activate Data Logging.

CONNECTING SENSORS

The fiber-optic oxygen, pH and temperature sensors, as well as optical fibers needed for read-out of contactless sensors are connected to the ST-connectors of the FireSting®PRO (1 to 4) with a male fiber plug.

• Remove the black caps from the plug of the sensor / fiber.
• Remove the red caps from the sensor ports at the FireSting®-PRO (the red caps should be put on again if it is not in use anymore to protect the optics).
• Insert the male fiber plug of the sensor cable into the ST-port (female fiber connector) of the FireSting®-PRO and turn the bayonet coupling gently clockwise until the plug is locked firmly.

OPTICAL SENSORS

The FireSting®-PRO is compatible with a broad range of optical oxygen, pH and temperature sensors from PyroScience. For an overview of available optical sensor types, please see the PyroScience website. FireSting®-PRO devices labeled with “ready for precal pH” and all devices with SN>23360000 can be used for calibration free measurements with precalibrated pH sensors.

EXTENSION PORT

The extension port of the FireSting®-PRO consists of the two connectors X1 and X2 (fitting connector plugs can be obtained from Phoenix Contact item no. 1778887 and 1778861).

6.1 Connector X1 (Power, Digital Interface, Analog In)
The pin configuration of the connector X1 is given in the table below. Pins 1-2 (GND and VCC) can be used for providing an external power supply (3.5…5.0 VDC), if the FireSting®-PRO should not be powered via the USB port. The transmit and receive pins of the UART-interface are given at pins 4 (TXD) and 5 (RXD) (communication protocol on request). When using the UART-interface it is recommended to connect pin 3 (/USB_DISABLE) to pin 1 (GND), which disables the USB interface.
Pin 6 (/PAUSE_BROADCAST) and Pin 7 (/TRIGIN) are related to the so called “broadcast mode” which can be configured in the PC control software (e.g., Pyro Workbench or Pyro Developer Tool). During broadcast mode, the device triggers itself periodic measurements which can be read out from the analog outputs or from a text message transmitted via the USB/UART interface. For more details refer to the manual of the respective control software are to the communication protocol (available on request).
Pin 7 (/TRIGIN) acts as a trigger input for the broadcast mode. Note, the option “Enable Trigin” must be enabled in the broadcast settings in the control software. Every time this pin is connected to pin 1 (GND) then an additional broadcast measurement is triggered. Pin 6 (/PAUSE_BROADCAST) acts as a master switch of the broadcast mode. As long this pin is tied to pin 1 (GND), then the broadcast mode is paused. Neither periodic broadcast measurements, nor triggered broadcast measurements are performed.
