• For 0.00~2.50%O2 ... +/- 0.05%O2 +/- 1digit (in a dry gas of oxygen and nitrogen)
• Transmission method: 0~100% of the output signal is output to 0.00~2.50, and 8~100% of the output signal is output to 2.0~25.0
• Alarm function: Measured value alarm ...
• Alarm setting code: Densitometer mode *1
• *1 Alarm setting "A" is set to the initial value at the time of shipment, and alarm setting "B" is set to the state of alarm setting "0" for unspecified alarm value and alarm output operation.
• Lower warning value: specified within 0~26% *2
• Upper warning value: specified within 0~26% *2
• *2 The lower alarm value cannot be set to a value larger than the upper alarm value or cannot be specified. When alarm release alarm is held, it is released by front reset key.
