Calibration :

Precautions :

  • Keep the tester dry. Precipitation and all types of liquids or moisture can contain minerals that will corrode electronic circuits. If your tester gets wet, remove the battery, and allow the tester to dry completely before replacing it.


  • Do not use, store or expose the gauge in dusty and dirty areas. Its moving parts can get damaged.


  • Do not use, store or expose the gauge in hot areas. High temperatures warp or melt certain plastics.


  • Do not use, store or expose the gauge in cold areas. When the gauge returns to its normal temperature, moisture can form inside the gauge.


  • Do not attempt to open the gauge other than as instructed in this handbook.


  • Do not drop, knock, or shake the gauge. Rough handling might break the fine mechanics.


  • Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the gauge.


  • Do not paint the gauge. Paint can clog the moving parts and prevent proper operation.
