• Question: What action should you take if the Zero check proves unsatisfactory?

• Answer: Repeat the Zero check in a gas free area. If this does not correct the error/fault after a few attempts the Gascoseeker should be put through the depot test equipment. If this does not work, this instrument will require recalibration (follow local procedures).

• Question: What would indicate that the batteries need replacing and how would you go about changing them?

• Answer: BATT FAULT would be displayed. If BATT flashing is displayed, there would be 1-2 hours of use left, at normal operating temperature. The instrument should be switched off and placed on a firm base where the two screws should be removed using the tool provided. All four batteries should be replaced using only batteries provided by SGN for use with Gascoseekers. This should always be done in a gas free area.

  soundness test still fails, the Gascoseeker should be returned for repair (follow local procedures)
