too low

• Air leaking into probe, tubing, water trap, connectors

or internal to analyzer.

• Oxygen cell needs replacing.

• Oxygen reading is above 18%.

• Analyzer just continually beeps

• Turn dial back to MENU and press

• BAT only shows 65 with fully

charged NiMh batteries fitted

Alkalines deliver 1.5 V per cell. Fresh alkalines might

give a BAT value of 80 or so.
