P-1000 1.0 Introduction The Detcon Model P-1000 H2S Process Analyzer is a portable gas analyzer designed to provide accurate measurement of Hydrogen Sulfide gas concentrations. The portable battery powered instrument utilizes advanced electrochemical sensor technology and microprocessor based electronic control circuitry that includes a built in data logger. Stored data can be downloaded to a spreadsheet and used to create trend graphs.
P-1000 1.1.2 Universal Transmitter Module (UTM) The UTM is microprocessor based, and is packaged as a field replaceable module, which is built into the P1000 enclosure. Circuit functions include a PIC microprocessor, 2-line alphanumeric display, magnetic programming switches, and a linear 4-20mA DC output. Field wiring is terminated on the bottom side of the UTM cover. The UTM also provides an LCD contrast adjust pot and a protective input fuse. 1.1.
P-1000 1.2 Principle of Operation Sample gas is fed into the unit via the Process Sample Inlet port on the side of the unit. The flow of the gas is regulated by the Rotameter, and passed through the coalescing filter to remove moisture and condensation. The nominal flow rate should be 500cc/min. with a minimum flow rate of 200cc/min. and a maximum of 1000cc/min.

P-1000 2.0 Installation and Start Up Before the unit can be operated on the battery, the battery should be charged completely. The battery charger should be connected to the cannon plug labeled “Charger Power In 12VDC”, on the side of the unit, and plugged into a 120VAC receptacle. The unit power switch should be in the “OFF” position during charging. The charger indicator will signal when the battery is fully charged by illuminating the Green LED on the charger.
P-1000 If the latest version of Java (1.4.2) is not installed, the installer will install it. HOBOware™ will inform you if your Java version is not up to date. Follow the screen prompts to install the HOBOware™ software. HOBOware™ should open automatically when the installation is complete (unless the Launch HOBOware™ box is un-checked on the Completing the HOBOware Setup Wizard dialog before clicking Finish). If it doesn’t, double-click the HOBOware™ icon on the desktop or Quick Launch menu.
P-1000 7. Click the Launch icon on the toolbar. This displays the logger’s Launch window. Launch windows vary for each type of logger, but most should look similar to Figure 6. 8. Review the default Launch settings. Enter an appropriate name in the Description field, (Test1 in this example) and select Channel 1in the Channels to Log select box. Figure 6 HOBO Launch Window 9. Select Scaling to open the Linear Scaling Window (Figure 7). The scale channel check box should be checked.
P-1000 logging. HOBOware™ displays the progress of the launch and warns the user not to unplug the logger while it is being configured. NOTE: Launch settings are discussed in depth in “Chapter 2: Working with loggers.” in the HOBOware™ Users Guide. 11. To disconnect a logger, simply unplug it from the USB cable or the computer. 2.3 Analyzer Initial Operational Tests After a warm-up period has been allowed for, the sensor should be checked to verify sensitivity to its target gas.
P-1000 5. Save the file with an appropriate name for later recall. The Software will then prompt for a Plot Setup. Figure 9 Plot Setup Screen 6. HOBOware™ will then display a graph of the data logged during the Initial Operational Tests of the Analyzer. Figure 10 H2S graphic display NOTE: the sample rate of Figure 10 was set to 1-second intervals for the purpose of clarity.
P-1000 3.0 Analyzer Operating Software Operating software is menu driven with operator interface via the use of two magnetic program switches located under the front panel. The two switches are labeled “PGM 1” and “PGM 2”. The menu consists of 3 items which include sub-menus as indicated below. (Note: see section 3.5 for a complete software flow chart.) 01. Normal Operation a) Current Status 02. Calibration Mode a) Zero Cal b) Span Cal 03.
P-1000 The time weighted average and peak data (last 8 hours). Menu item appears as: “TWA: xx PPM / PK: xx PPM@ –xx Min” Estimated remaining sensor life. The menu item appears as: “Sensor Life / XX%” Calibration span gas level setting. The menu item appears as: “Auto Span Level / XX PPM” Date. The menu item appears as: “Present Date/ mm/dd/yy” Last successful span date. The menu item appears as: “Last Span Date / mm/dd/yy” Temperature. The menu item appears as: “Present Temp / XX°C” 3.3.

P-1000 4.0 Calibration 4.1 Calibration Procedure – Zero Material Requirements Zero Air or N2 gas cylinder a) Connect zero air or N2 gas to the “Span/Zero Gas Inlet Port” and switch the 3-way valve to the “Calibrate” position. Apply zero air or N2 gas at a rate of 500cc/min for 5 minutes prior to continuing. b) Enter the calibration menu by holding the programming magnet stationary over “PGM 1” for 3 seconds until the display reads “1-Zero Cal 2-Span Cal”, withdraw the magnet.
P-1000 must be programmed via the calibration gas level menu before proceeding with span calibration. Follow the instructions below for span calibration. 1) Verify the current calibration gas level setting as indicated by the programming status menu. To do this, follow the instructions in Section 5.1 and make note of the setting found in the calibration span gas level setting. The item appears as “Auto Span Level / XX PPM”.
P-1000 Figure 14 Auto Span Sequence 4) From the calibration menu “1-Zero Cal 2-Span Cal” proceed into the span adjust function by holding the programming magnet stationary over “PGM 2” for 3 seconds. The display will ask for the application of the target gas and concentration. The display reads “Apply XXPPM Span Gas” (The ‘X’s indicate the concentration requested). 5) Apply the calibration span gas at a flow rate of 500cc/min..
P-1000 gas so that the sensor recovers toward zero. When the signal level falls below 10% of full scale the display changes to “Return to Normal Operation”. 9) Turn off and remove the zero air or N2 gas, and remove the gas from the unit. Turn the 3-way “Calibrate/Sample” valve to the “Sample position”. Adjust the flow Rotameter for a flow rate of 500cc/min. Span Calibration is complete. 4.2.1 Additional Notes a) Upon entering the calibration menu, the 4-20mA signal drops to 3.
P-1000 ¾ Date. The item appears as: “Present Date/ 5/1/01” ¾ Last successful span date. The item appears as: “Last Span Date / dd/mm/yy” ¾ Temperature. The item appears as: “Present Temp / XX°C” c. Exit to normal operations by holding the programming magnet over “PGM 2” for 3 seconds, or the sensor will automatically return to normal operation in 30 seconds. 5.
P-1000 adjustment. Use the programming magnet to adjust “PGM 1” to increase or “PGM 2” to decrease the display reading until the reading is equal to the desired year. e) To retain the newly entered value, hold the programming magnet over “PGM1” for 3 seconds. f) Exit to normal operation by holding the programming magnet over “PGM 2” for 3 seconds, or the sensor will automatically return to normal operation in 30 seconds. 5.
P-1000 Memory Fault If new data points cannot successfully be retrieved from memory, the display will indicate: “Memory Fault”. Comm Error If the ISM and UTM are not communicating properly, then the UTM will report “Comm Error”. 6.0 Exchanging ISM Modules A key feature of the UniTox™ product is its complete universality (exchangeability) between any combination of ISM and UTM.
P-1000 1. Re-Install ISM. 2. Swap ISM and UTM with another functional pair to determine if ISM or UTM is the problem. 7.1.3 No LCD or 4-20mA signal activity with power applied Probable Causes: Blown input fuse, Insufficient Operating Voltage, Miss-wired connection. 1. Check/Replace Fuse. 2. Check for correct polarity and verify Operating voltage at the UTM input terminals. 3. Check status of external field wire I.S. Barrier. 4. Replace UTM with functional UTM. 7.1.
P-1000 7.1.11 LCD Not Easily Read 1. Adjust contrast potentiometer (Section 7.2). 7.2 Display Contrast Adjust Detcon UniTox™ sensors feature a 2-line, 16-character liquid crystal display. Like most LCD’s, character contrast can be affected by viewing angle and temperature. Temperature compensation circuitry included in the UniTox™ design will compensate for this characteristic, however temperature or operating voltage extremes may still cause a shift in the contrast.
