Note: While the instrument can detect up to 25 % oxygen in
ambient air, it is approved for use only up to 21 % oxygen.
Read and follow all instructions carefully.
• Perform a bump test before each day's use and adjust if
necessary.
• Perform a bump test more frequently if exposed to silicone,
silicates, lead-containing compounds, hydrogen sulphide, or
high contaminant levels.
• Recheck calibration if unit is subjected to physical shock.
• Use only to detect gases/vapours for which a sensor is
installed.
Do not use to detect combustible dusts or mists.
•
• Make sure adequate oxygen is present.
• Do not block sensors.
• Have a trained and qualified person interpret instrument
readings.
