Scope of this manual This manual provides installation, operation and routine maintenance instructions for the Servomex 5100 i.s. Portable Gas Analyser, abbreviated to "5100 i.s." in the remainder of this manual. Safety information Read this manual and ensure that you fully understand its content before you attempt to install, use or maintain the 5100 i.s. Important safety information is highlighted in this manual as WARNINGs and CAUTIONs, which are used as follows: WARNING Warnings highlight specific hazards which, if not taken into account, may result in personal injury or death. CAUTION Cautions...

Gas sample measurements are shown on the 5100 i.s. display (see Section 4.2). The 5100 i.s. is supplied with an internal rechargeable battery, and with a power supply unit: • The 5100 i.s. is suitable for sampling gases in hazardous areas (refer to Section 2.9) when the 5100 i.s. is operated as a portable unit (powered by the battery) and is disconnected from the power supply unit. • When it is connected to the power supply unit and the power supply unit is connected to the electrical supply, the 5100 i.s. must only be used (to charge/ recharge the battery or set up the analyser) in safe areas....

SPECIFICATION WARNING You must install and use the 5100 i.s. in accordance with the requirements of this section and subsequent sections of the manual. If you do not, the protection facilities incorporated into the design of the 5100 i.s. may not operate as intended, sample gas measurements may not be accurate, or the 5100 i.s. may be damaged. General Dimensions (width x depth x height) Mass (minimum to maximum) Electrical supply requirements Power supply unit 5100 i.s. * As supplied by the power supply unit (through a centre pin +ve connector). 2.2 Environmental limits WARNING The 5100 i.s....

Calibration gases WARNING If the 5100 i.s. is specified for use with carbon monoxide or carbon dioxide, the concentrations of the gases used may be above their respective threshold limit values, and should therefore be considered toxic. You must therefore carry out a risk assessment before you use the 5100 i.s. with such gases. The maximum inlet pressures of such gases are: • For a 5100 i.s. with an internal sample pump: 110 kPa absolute (1.1 bar absolute, 16 psi absolute). • For a 5100 i.s. with an AFCD: 35 kPa gauge (0.35 bar gauge, 5 psi gauge). WARNING You must only use the 5100 i.s. with...

Performance: standard oxygen sensor WARNING You must only use the 5100 i.s. with oxygen enriched sample/calibration gases (with oxygen concentrations higher than 21%) when it is located in a safe area. The display indication given below is the default indication. You can configure the 5100 i.s. to provide other display indications (see Section 6.5). Display indication Measured volume % oxygen Full Scale Range 0 to 100% oxygen: see the warning above Intrinsic error (accuracy) Zero drift per week Output fluctuation Response time # Flow variation effect Zero temperature coefficient Span temperature...
