OPERATION
Gas Check 5000is both have menu keys for user accessible settings. However normal use of the Gas
Check would not involve any menus, because these are only needed to set up the instrument for
your application, after which the instrument stores the settings internally when the instrument is
switched off.
The display of information on the Gas Check 5000is depends on whether the instrument has been
keyed into the set up menus or is simply being used for leak detection. The Gas Check 5000is menu
displays utilise 3 lines of information while the normal display uses 2 or 3 lines; in each case the
lowest line is for status information while the upper line(s) show(s) the menu topics or the leak rate
values.
You may like to gain some confidence in the operation by simply using the control keys as in section
4.1.1 although if it has not yet been used you should carefully fit the battery clip in accordance with
section 5.2.
Please take note of the warnings and cautions when fitting batteries or when in potentially hazardous
areas.
