The sensing membrane emits light by returning to the ground state after the sensing
material is excited by the excitation light. The light-emission depends on the oxygen
concentration around the sensing membrane. The long-term stable measurement canbe conducted by use of the reference light which gives standard light-emission.

1: When replacing the detector, zero and span calibration work are required.
2:It is a numerical value based on our standard usage record.Regular calibration and maintenanceare required for stable measurement.

Class-D grounding 4(for instrument grounding)
1:±Io1output is the selected one of dissolved oxygen concentration or dissolved oxygensaturation.
2:ALM2 output is the selected one of level alarm or membrane replacement timing alarm.
3:The AC voltage output to the control output (AC OUT) is the same as the power supplyvoltage(90 to 264VAC 50/60Hz) to the converter.
The voltage specifications of the standard cleaning mechanism are rated 100VAC, 50/60Hz.
Please contact us if the power supply voltage to the converter is other than 100VAC.
Also, do not short-circuit the terminals because it may cause equipment failure.
4:Be sure to connect the grounding terminal(G) to ground potential.
(Class D grounding : ground resistance of 100Ω or less.)
