    The instrument is designed to the latest standards and is certified for use in Hazardous Areas. Figure 1-1 Gasurveyor 500 series Instrument The Gasurveyor 500 can contain up to six gas ranges with the following ranges being possible: •...
  • Page 16 Gasurveyor 500. The instrument that this manual has been supplied with is part of the Gasurveyor 500 series, e.g. Gasurveyor 521: LEL/Vol ; Oxygen. Gasurveyor 531: LEL/Vol ; Oxygen ; Hydrogen Sulphide.
  • Page 17 Audible and Visual Geiger indication, enabled in the PPM Flammable range, provides indication of gas concentration increase via the increased rate of sounder and LED pulse. • Manual and automatic datalogging. • Directly interfaces with the GMI Auto Test Calibration Systems.
  • Page 18 GASURVEYOR 500 USER HANDBOOK...

  • Page 19: General Information

    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 20: Volume Gas, 0 To 100

    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 21 GENERAL INFORMATION correction techniques are used to minimise drift. The ppm range includes a manual zeroing procedure. The ppm range has the option of using a ‘threshold’. By this, we mean that we can display either a blank screen or simply a zero (0) on the display, up to a pre-set level. This allows small readings, which may not be due to the gas we wish to find or very small amounts of gas, to be ignored if they fall below any pre-set action levels.

  • Page 22: Threshold Display Options

    GASURVEYOR 500 USER HANDBOOK When the instrument is switched on, the visual Geiger indication is operational. To activate the audible Geiger indication, press and hold Switch Four ( 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 23: Toxic Ranges

    The instrument, by default, will have alarm levels for the Flammable LEL, Oxygen, and Toxic gases pre-set. The Gasurveyor 500 series has the facility to have two (2) instantaneous alarm levels for each range in the instrument. These are described as LOW and HIGH. By default, only the high instantaneous is activated.

  • Page 24: Alarm Functions

    GASURVEYOR 500 USER HANDBOOK When operating in Confined Space Monitor (CSM) mode, the instrument has two (2) toxic monitoring alarm levels set by default. These are the STEL (Short Term TWA) and LTEL (Long Term TWA). The option is to have these two alarm levels disabled.

  • Page 25: Geiger Indication

    (if activated) and the LED, pulse at an increasing rate. Datalogging The Gasurveyor 500 series memory can store up to 1000 logged entries which are dependent on number of Gas ranges and duration of each ON / OFF session. The memory will overwrite entries in the event of an overflow.

  • Page 26: Csm Mode

    GASURVEYOR 500 USER HANDBOOK CSM Mode The Gasurveyor 500 instruments, by default, have automatic and manual datalogging enabled when operating in CSM mode. During automatic datalogging the instrument stores the values of all gas ranges together with the current time and date at 60 second intervals.

  • Page 27: Batteries

    The instrument will then turn off. There are three GMI Battery Chargers: a Standard Charger, a Flatbed Charger and a Smart Charger. The Smart Charger has both slow and fast charge options as well as a serial link for communications with the instrument.

  • Page 28: Filters

    GASURVEYOR 500 USER HANDBOOK Filters A number of different filter types are available from GMI. The minimum recommendation is a cotton particulate filter and a hydrophobic filter which are incorporated in the probe handle assembly, available as an accessory. Filters must be checked at frequent intervals and where appropriate changed to ensure a clean sample path.

  • Page 29: Operating Instructions

    OPERATION OPERATING INSTRUCTIONS Operating Modes The Gasurveyor 500 is a dual configuration instrument. It operates as a Confined Space Monitor (CSM) or as a Combustible Gas Indicator (CGI) depending on the button used to switch it on. For Confined Space Monitor operation the instrument must be switched on by pressing and holding Switch One ( for approximately one second.

  • Page 30: Confined Space Monitor (Csm) Operation

    GASURVEYOR 500 USER HANDBOOK Table 3-4 Display Options Clearing Alarms A double press of Switch Four ( ) will clear an alarm if latching, or acknowledge the alarm for 60 seconds if non-latching. Double pressing will only cancel the alarm when the gas level is below the threshold set in the instrument.

  • Page 35: Notes On (Default) Csm Mode

    OPERATION Notes on (default) CSM mode: • Alarms are always active in CSM mode. • The pump cannot be switched off in CSM mode. • In CSM mode the instrument does not switch off automatically. • In CSM mode automatic datalogging is enabled by default.

  • Page 36: Combustible Gas Indicator (Cgi) Operation

    GASURVEYOR 500 USER HANDBOOK Combustible Gas Indicator (CGI) Operation In this mode the instrument operates as a gas indicator drawing a sample via a probe from points where gas is suspected to be present. Alarms, by default, are disabled in CGI mode, as the instrument is generally used for measuring gas levels rather than monitoring for the presence of gas.

  • Page 37: Calibration Date Features

Using the fast charge option a battery pack can be 90% recharged in approximately 60 minutes and fully recharged in 120 minutes. To ensure optimum life length, the rechargeable pack should be fully discharged and charged on a regular basis of, at least, every three months.

  • Page 46: 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) using the special tool provided.

  • Page 47: Filter Replacement

    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 49: 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 50: 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.
