Page 4: Introduction
INTRODUCTION Scope and definitions This manual provides installation, operation and maintenance instructions for the Gas Check 3000 and 3000is. You must use the Gas Check as specified in this manual. Read this manual before you install and operate the Gas Check. Important safety information is highlighted as WARNING and CAUTION instructions;... -
Page 5: Applications
This means that you can use the Gas Check to detect any gas other than that in which the Gas Check is zeroed. 1.4 Applications You can use the Gas Check on many types of applications, including those listed below. ... -

2 TECHNICAL DATA 2.1 General Operating temperature range Gas Check 3000 0 to 50 °C 32 to 122 °F. Gas Check 3000is 0 to 40 °C 32 to 104 °F. Storage temperature range -25 to 70 °C -13 to 158 °F. Materials of construction Storage case Polypropylene with polyester foam insert... - Page 7 All gases and vapours having a different thermal conductivity to the ambient air on which it was zeroed. The larger the difference the greater the sensitivity, so that Gas Check is not highly sensitive to the gases normally found in large concentrations in the ambient air, e.g. N2 (nitrogen) and O2 (oxygen). For ease of use the Gas Check groups gases having similar thermal conductivity into one of the 5 gas groups shown in Table 1.

2.3 Battery data Note: the energy storage capacity of batteries is affected by temperature. The data in Table 2 is for an ambient temperature of 20 °C (68 °F). WARNING For Gas Check 3000is Do not modify the Gas Check 3000is equipment to allow any recharging. For Intrinsic Safety T4 Rating in the Gas Check 3000is rechargeable batteries (e.g. -

Page 12: Display
Display 4.2.1 General The display is arranged to show the leak rate and other status including user changes to the settings. In normal use the upper portion of the display is used for a large size digital representation of the leak rate (see Section 4.2.2) and status information is shown as symbols (see section 4.2.3) appearing in the lower portion. -
Page 13: Audio & Visual Outputs
4.2.3 Other display symbols Small display indicators show zeroing, nozzle fitted, peak hold, auto range and low battery voltage. Zeroing This symbol appears whilst the Gas Check is zeroing then it disappears. Auto range This symbol shows when the Gas Check leak rate is not fixed within one range. Nozzle This symbol indicates that the Gas Check is being used with the Nozzle on. -

4.4.2 Remove the Gas Check nozzle or change the probe (if required) Switch off the Gas Check. Refer to Figure 5. Hold the nozzle (1) by its wide base and gently twist and pull it to remove it . With the small end of the box spanner towards the Gas Check, guide the end of the probe (2 or 7) through the middle of the box spanner. -
Page 15: Recommended Leak Search
Gas Check remembers the settings on instrument power off so that the operator rarely if ever has to alter any of them. The settings for gas group, auto range, peak hold and nozzle are shown on the display. The response of Gas Check can readily be checked against a Portable Reference Leak (PRL) traceable calibration accessory. -

4.6.3 Leak detection at pipe joints Use the same procedure as for leak detection along seams (see Section 4.6.2), however move the probe (or nozzle) around the joint at approximately half the speed specified in Section 4,.6.2. Light gases (such as hydrogen and helium) diffuse quickly into air, so an apparent leak on the side or top of a joint may actually be a leak at the bottom of the joint. - Page 17 Refit the required probe to the Gas Check: refer to Steps 4 to 6 in Section 4.4.2. Place a light wipe of thin petroleum jelly around the inner face of the wide part of the nozzle, then fit the nozzle to the Gas Check. Place the Gas Check and nozzle (and the long probe, if just removed) in its storage case.
- Page 18 Note: A spare battery holder is supplied with the Gas Check. Refer to Figure 6. Turn over the Gas Check so that the battery compartment is at the top: see detail On the Gas Check 3000, use a small coin, screwdriver or your fingernail to press the catch (1) on the battery compartment cover (2), then pull up and remove the cover: see detail B.
