• alarm setting
• Densitometer Mode Type I (Optional by User)
• Default: 18% lower limit, 26% upper limit
• Buzzer, Lamp, Relay With Output, Output Hold
• Display range: 0.0~25.0%O2/0.00~2.50%O2 Automatic switching
• Transmission output range: output corresponding to 0.0~25.0%O2
• *The display range and transmission output range can be combined in the following formats: 00, 11, 20, 22. However, only 00 can be specified when the alarm setting is in the oxygen deficiency meter mode.
• In the case of display range 1 in the moat meter mode Type I, the initial alarm value is lower limit 0.00%, upper limit 2.50%.
• Measurement Principle: Zirconia Solid Electrolyte Method
• Air sampling method: natural diffusion type
• Response time: 90% response within 20 seconds
• Oxygen detection element position: fixed to the dedicated holder in the main body case
• Measurement value display: Digital display with 3-digit yellow-green LED
• Measurement Range (Resolution): 0.00~2.50 (0.01)/2.0~25.0 (0.1)%O2 (Automatic Range Switching)
• accuracy rating
• For 0.0~25.0%O2 ...±0.5%O2±1digit
• 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: within 0~26% Optional *2
• Upper warning value: within 0~26% Optional *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.
• Relay output ON/OFF: Optional setting
• Buzzer Blow On/Off: Optional
• Lamp ON/OFF: Optional setting
• With/without output holding: Optional setting
• Detection element abnormality alarm: When the heater current to the oxygen detection element is abnormal, relay output is ON, buzzer is blown, and lamp is lit regardless of the content of the measured value alarm.
• Power failure warning: When the power supply to the tester is OFF or when the fuse is broken, relay output is ON.
• Alarm relay output: number of output circuits (2), number of output circuits (1) in case of detectors separated type, output capacity (Resistive Load 110 V AC 0.2 A, 24 V DC 1 A/Inductive Load 110 V AC 0.1 A, 24 V DC 0.5 A)
