  • Page 11: Introduction

    INTRODUCTION The PPM Gasurveyor 500 is a two button instrument designed to measure Parts Per Million, Lower Explosive Level and Volume flammable gas. The instrument is designed to the latest standards and is certified for use in Hazardous Areas. The PPM Gasurveyor 500 contains the following ranges:...
  • Page 12 PPM GASURVEYOR 500 USER HANDBOOK As the PPM Gasurveyor 500 has a wide variety of available user selected options, it is not possible to provide an operator handbook specific to each possible variation, therefore, what we have pro- vided in the following pages is the standard de-...

  • Page 13: General Information

    GENERAL INFORMATION Ranges of Operation LEL, 0 to 100% The LEL range indicates the explosibility of the flammable gas in the sample. This is displayed as a percentage of the lower explosive limit (LEL) of the gas. The instrument range is displayed in the top right corner of the display as % LEL.

  • Page 14: Volume Gas, 0 To 100

    PPM GASURVEYOR 500 USER HANDBOOK Volume Gas, 0 to 100 % This range displays the total volume of a specific flammable gas with respect to air. The calibration gas is shown on the service label and for the purpose of this handbook is assumed to be methane.

  • Page 15: Ppm Flammable 0 - 1000 Ppm

    GENERAL INFORMATION PPM Flammable 0 – 1000 ppm This range is used to measure very low levels of gas and indicates the parts per million concentration of the gas in air (1000 ppm is equivalent to 0.1% Volume Gas). The digital display reading resolves to 5 ppm with the analogue bargraph following in steps of 40 ppm.

  • Page 16: Threshold Display Options

    PPM GASURVEYOR 500 USER HANDBOOK disabled. To enable audible Geiger indication, press and hold Button Two The display changes between PPM and Aud (if enabled) as shown in Figure 2.3. Figure 2.3 PPM Range Threshold Display Options The ppm range will by default, if a threshold is selected, display below the threshold as zero (0) on the screen.

  • Page 17: Search Mode

    GENERAL INFORMATION Search Mode Search mode is an enhanced variant of the ppm flammable range with increased resolution and faster response. Search mode can be used for detecting leaks which can then be classified using the more accurate ppm, LEL and Volume Gas ranges.

  • Page 18: Geiger Indication

  • Page 20: Filters

    Rechargeable Battery Pack OPERATOR MAINTENANCE Filters The PPM Gasurveyor 500 has a cotton particulate filter located behind the instrument inlet nozzle. The filter should be checked at frequent intervals or when the SAMPLE FAULT flag appears in the instrument display, and where appropriate, changed to ensure a clean sample path.

  • Page 21: Before Use Checks

    GENERAL INFORMATION Before Use Checks The following checks should be carried out before using the instrument on site: The instrument is clean and in good condition. The batteries have sufficient power left in them for the intended use of the instrument. Any filters are clean and in good condition.

  • Page 23: Operating Instructions

    The instrument has two modes of operation which are accessed by switching the instrument ON with either Button One or Button Two , as shown in Figure 3.1: INST. PUMP RANGE PPM GASURVEYOR 500 PPM ZERO Figure 3.1 Instrument Front Plate...

  • Page 24: Mode 1

    PPM GASURVEYOR 500 USER HANDBOOK Mode 1 Switching ON with Button One provides three gas ranges, PPM, LEL / Gas, and Search. Note: Geiger feature is not operational in Search or PPM range when instrument is switched on in normal mode.

  • Page 25: Calibration Date Features

    OPERATION Calibration Date Features At the end of warm-up and before the PPM Gasurveyor 500 instrument is ready for measuring, the instrument will indicate on the display when the next calibration is due. This will be displayed as month and year, as shown in Figure 3.3: Calibration Due (Alternate flash)

  • Page 26: Switching Off

    PPM GASURVEYOR 500 USER HANDBOOK Switching Off A double press of Button One turns the instrument off immediately. The instrument switches off automatically after 30 minutes. ‘OFF’ is shown in the top right hand corner of the display. Pressing any button cancels this automatic switch-off.

  • Page 27: Zeroing The Ppm Or Search Range

    OPERATION Zeroing the ppm or Search Range A double press of Button Two zeroes the ppm range. This should be carried out in fresh air and may take a few minutes to reach the optimum zero stability. The display in Figure 3.4 occurs if a large adjustment is needed to reach the zero point.

  • Page 29 OPERATION ‘SAMPLE FAULT’ This indicates a problem with the instrument’s flow due to the sample path being blocked, water ingress, a blocked filter or pump failure. In normal mode the pump stops automatically. The sample line, filters etc. should be checked for water ingress or blockage and Switch One should then be used to restart the pump.
  • Page 30 PPM GASURVEYOR 500 USER HANDBOOK As the battery power continues to fall, the LCD flashes a ‘BAT FAULT’ message. Subsequently the LCD displays ‘OFF’ and the instrument automatically switches off. The batteries should be replaced immediately. ‘BAT FAULT’ This indicates that the batteries require replacing.

  • Page 31: Operator Maintenance

Standard Charger The GMI Standard Charger takes approximately 14 hours to charge a flat battery. Note: The 4-button instrument is for illustration purposes...

  • Page 32: Flatbed Charger

    PPM GASURVEYOR 500 USER HANDBOOK Flatbed Charger The GMI Flatbed Charger allows the Gasurveyor’s battery pack to be charged in NORMAL mode, which takes approximately 14 hours to charge a flat battery. The Mode Select Switch can then be set to STAND-BY, where a trickle charge will maintain the battery in a fully charged state of readiness.

  • Page 33: Replacing The Battery Pack

    OPERATOR MAINTENANCE The GMI Smart Charger provides both fast and standard charging facilities and can charge an instrument and spare battery pack simultaneously. Using the standard charging option, a battery pack can be recharged in 12 hours from a fully discharged state. Using the fast charge option a battery pack can be 90% recharged in approximately 60 minutes and fully recharged in 120 minutes.

  • Page 34: Recharging The Battery Pack

    Replacing Alkaline (LR20) Dry Cell Batteries All four batteries should be replaced at any one time and in a safe area. GMI only recommend the use of Energiser or Duracell batteries. 1) Loosen the two instrument base screws (4mm hex)
  • Page 35 OPERATOR MAINTENANCE 2) Remove battery cover. 3) Remove the old batteries. 4) Check battery compartment for damage to spring contacts or corrosion on springs. Caution: Under no circumstances should rechargeable batteries be fitted in place of Alkaline batteries. 5) Insert four new batteries observing correct polarity indication in battery compartment base.

  • Page 36: Filter Replacement

    PPM GASURVEYOR 500 USER HANDBOOK Filter Replacement A cotton particulate filter is fitted behind the instrument inlet nozzle to minimise the danger of moisture and dust ingress. Caution: The instrument should never be switched on without a filter installed. If a blockage occurs the ‘SAMPLE FAULT’ indicator is displayed.

  • Page 37: Probe Handle Assembly - Part No. 13561

    OPERATOR MAINTENANCE 2) Discard the filter. 3) Check nozzle O-ring for damage, and replace if necessary. 4) Place a new cotton particulate filter in the nozzle recess, then insert nozzle and filter in the instru- ment inlet. 5) Use a coin once again, turning in a clockwise di- rection, to tighten the nozzle in the instrument in- let.

In-line Water Filter (Accessory) To replace the Hydrophobic Filter in the Water Filter Housing assembly, proceed as follows: 1) Unscrew the filter housing assembly (Figure 4.4).
  • Page 40 PPM GASURVEYOR 500 USER HANDBOOK 3) Check Filter Housing Sealing Washer and Probe Sealing Washer for signs of damage or wear and replace if necessary. 4) Fit new Hydrophobic Filter. Note: The filter should be installed with the yel- low label on the filter, facing the yellow label on the housing flange.

  • Page 41: Calibration

    CALIBRATION The instrument has been calibrated for a particular flammable gas mixture. Where any doubt exists the instrument should be returned to GMI or an authorised distributor for calibration. Four methods of calibration are possible: • Field Calibration. See APPENDIX B, FIELD CALIBRATION for further details.

  • Page 42: Calibration Validity

    12 month period can be expected. This is no guarantee, however, as the precise application of the product is unknown to GMI. Individual codes of practice may dictate shorter periods. Regular checking establishes a pattern of reliability and enables the calibration check period to be modified in line with operational experience.
