n Notes on UseThe OX400 is a product that conforms to the general safety requirements of the IEC standard. Be sure to observe the following precautions when you operate it.

HandlingPrecautions• Installation location

The OX400 is structurally non-explosion proof so you cannot use it in an explosive atmosphere. Also, see 3.1, “Installation Location.”

• Power supply BesuretocheckthatthepowersupplyvoltagespecificationoftheOX400matchesthevoltage of the power supply before turning on the power.

• Protective ground Be sure to connect the power plug of the OX400 to the 3P socket with a protective ground pin in order to prevent electric shock.

• Fuse Besuretouseadesignatedfuseinordertopreventafire.Besuretoturnoffthepowerbefore replacing the fuse. Never use a fuse holder other than a designated one.

• Removing cover ThereisaheatedareainsidetheOX400,andtouchingitdirectlymaycauseaburninjury.Never remove the cover except to replace the sensor.

<INTRODUCTION>

• Before connecting wires to the terminal block on the rear panel of the OX400, remove the powerplugfromthesocketinordertopreventelectricshock.Afterfinishingthewiring,secure the removed special terminal cover with screws.

• The OX400 is a measuring instrument intended to be installed indoors, so do not install it in a location that is exposed to direct sunlight, rain, and wind.

• DonotusetheOX400inalocationthatmaybesubjecttovibrationsandimpact.Doingsomay cause destruction and damage to the internal sensor.

• Do not apply a pressure of 30 kPaG or more to the gas inlet. Doing so may cause destruction of the suction pump and damage to the sensor. Be sure to reduce the sample gas pressure to the atmospheric pressure level before introducing the gas.

• Be sure to use metal piping for the gas piping; particularly when handling oxygen concentration in 1 vol % or less. Use of piping materials such as polyethylene, vinyl, rubber, andplasticmaycausesignificanterrorsinmeasurementsbecauseoftheirlargeoxygentransmission and absorption rates.

• Thepresenceofcorrosivegascomponents(H2S, SOx, HCl, NH3,HF,andthelike)orpotentiallytoxicelements(Si,Sn,Cd,Te,As,P,andthelike)inthesamplegasmaycausedeteriorationofthesensor.Besuretoremovethemwithanactivatedcarbonfilterorthelikein the previous step of the OX400 before introducing the gas.

• The presence of combustible gas in the sample gas may cause errors in measurements because oxygen in the sample gas will be consumed by combustion. Be sure to remove it withafilterorthelikeinthestepbeforeintroducingthesamplegasintotheOX400.

• Makesurethetemperatureofthesamplegasis50°Corless.• Be careful because the presence of water droplets in the sample gas may cause damage to

the sensor.• Keepthesupplygasflowrateandpressureasconstantaspossiblewhileintroducingthe

gas.• Keep the sample gas outlet open to the atmosphere during operation. If a gas line must

be used to discharge gas, use a gas line with a connector that has the largest possible diameter in order to prevent back pressure.

• Do not use the supplied power cord with another device. • Powercablesuffixcodesof“-D”canbeusedinJapan,becauseanothercabledoesn’t

conform to PSE marking.

n ProductDisposalThe instrument should be disposed of in accordance with local and national legislation/

3. Installation

3.1 InstallationLocationThe OX400 is a measuring instrument intended to be installed indoors. Install and operate it in a location that meets the following conditions in order to ensure the best performance. (1) Locationwherethereisnocorrosivegas.(2) Indoorlocationwherethereisnomechanicalvibration.(3) Locationthatisnotexposedtodirectsunlightandradiantheat.(4) Locationthatisfreeofdustanddirtparticles.(5) Locationwitharoomtemperatureof0to40°Candnocondensation.

WARNINGNeverusetheOX400inanexplosionhazardousarea.Doingsomaycauseafire,explosion,orthe like.

• The OX400 is a measuring instrument intended to be used indoors. Do not install it in a location that is exposed to direct sunlight, wind, and rain.

• DonotusetheOX400inalocationthatmaybesubjecttovibrationsandimpact.Doingsomay cause destruction and damage to the internal sensor.

• Do not apply a pressure of 30 kPaG or more to the gas inlet. Doing so may cause destruction of the suction pump and damage to the sensor. Be sure to reduce the sample gas pressure to the atmospheric pressure level before introducing it.

• Be sure to use metal piping for the gas piping; particularly when handling oxygen concentration in 1 vol % or less. Use of piping materials such as polyethylene, vinyl, rubber, andplasticmaycausesignificanterrorsinmeasurementsbecauseoftheirlargeoxygentransmission and absorption rates.

• Thepresenceofcorrosivegascomponents(H2S, SOx, HCl, NH3,HF,andthelike)orpotentiallytoxicelements(Si,Sn,Cd,Te,As,P,andthelike)inthesamplegasmaycausedeteriorationofthesensor.Besuretoremovethemwithanactivatedcarbonfilterorthelikein the previous step of the OX400 before introducing the gas.

• The presence of combustible gas in the sample gas may cause errors in measurements because oxygen in the sample gas will be consumed by combustion. Be sure to remove it withafilterorthelikeinthepreviousstepofintroducingthesamplegasintotheOX400.

• Makesurethetemperatureofthesamplegasis50°Corless.• Be careful because the presence of water droplets in the sample gas may cause damage to

the sensor. • Keepthesupplygasflowrateandpressureasconstantaspossiblewhileintroducingthe

gas. • Keep the sample gas outlet open to the atmosphere during operation. If a gas line must

be used for discharge gas, use a gas line with a connector that has the largest possible diameter in order to prevent back pressure.

4. PipingandWiring

4.1 PipingBe sure to observe the following precautions when connecting the gas pipe to the OX400.(1) TheconnectionsforboththegasinletandoutletareRc1/4or1/4NPT.Usethespecified

thread and securely connect the gas pipe so that no leakage will occur.

WARNINGWhen screwing in the pipe, be sure to hold the inlet hexagonal part in place with a wrench or the like. Not doing so and using a strong force when screwing in the pipe may cause the thread on the OX400 to rotate, resulting in damage to the internal pipe.

(2) Withrespecttopiping,useametalpipe.Useofmaterialssuchasplastic,vinyl,rubber,andthe like may result in inaccurate measurements due to the transmission of oxygen from the air and absorption onto the inside surface of the pipe. Particularly with respect to silicon tube, be careful because due to its large oxygen transmission rate, accurate measurements cannot be performed in the low concentration range.

(3) Becarefulofleakagefromthepipebecauseitmaycausemeasurementerrors.Particularlyin the low concentration range, take great care because even though the pressure inside thepipeispositive,oxygenmayflowfromtheairduetodiffusion,resultinginalargeerror.

(4) Fluctuationsofbackpressureatthepipeoutletmaycausemeasurementerrors,soalwayskeep the pressure at the atmosphere pressure level as much as possible during operation.

6.2 Calibration“CAL”Be sure to perform calibration in the measurement mode after the warm-up operation ends. Calibration cannot be performed during the warm-up operation. If an error occurs during calibration, that calibration will be invalid, and keys other than the [MODE] key become invalid. Holddownthe[MODE]keyfor2secondstoreturntothebeginningofthecalibration“CAL”andpress the [MODE] key again to return to the measurement state. With respect to the calibration methods of the OX400, there are four types of method. (1)3-point(All)calibration“ALL”

By performing calibration at the three points of 10 ppm, 1000 ppm, and Air, the linearity for the entire zone between 0-10 ppm and 100% O2 is guaranteed. Gas used for calibration is restricted to the ranges of O2 concentration as follows.

(1)8ppm≤10ppmgas≤20ppm (2)800ppm≤1000ppmgas≤2000ppm (3)O2concentrationinAir:20.6%(Normalairiswithinthisrange)

Note: Besuretousegasthatmeetsconditions(1),(2),and(3)forcalibration.(2)2-pointcalibration“2Pnt”

Select zero and span calibration points in the measurement range you will use to perform calibration. However, gas used for calibration is restricted to the ranges of O2 concentration as follows.

<When the range is 1000 ppm or less.> (1)Zerogasis8%FSormore.

(2)Spangasislessthan120%FS. (3) Betweenzeroandspanofthesmallestrangemustbemorethan20%FSoftheMANUAL

range. Example1:Twopointsof1ppmand3ppminthe10ppmrange Example2:Twopointsof20ppmand40ppminthe100ppmrange

< When the range is more than 1000 ppm.> (1)Zerogasis800ppmormore.

(2)Spangasis100%FSorless. (3)Betweenzeroandspanofthesmallestrangemustbemorethan2000ppm.

Example3:Twopointsof0.6%and0.8%inthe1%range Example4:Twopointsof20.6%and90%inthe100%range

(3)1-pointcalibration“1Pnt”Principally, 1-point calibration allows obtaining an accurate concentration in an area near the calibration point, but the error may become greater as the distance from the calibration point increases. This is a useful calibration method when it is used in some limited areas. Select one point in an area as close to the concentration you want to measure as possible to perform calibration. However, there are the following limits to the O2 concentration. Be sure to perform calibration in that range of the O2 concentration. O2concentrationlimits:0.9ppmormoreand12%orless,orbetween35%and100%.

(4)Aircalibration“AIR”This is air-only calibration. Ues the cleanest air possible to perform calibration.

Note:Ifyoupressthe[MODE]keyduringcalibrationtoexitthecalibrationmode,thatcalibrationbecomesinvalid.



IM 11M10B01-01E

If an error occurs during calibration, the ERR/ALM lamp turns on, and an error/alarm code is displayed on the sub-display. That calibration may become invalid depending on the error factor.

IM 11M10B01-01E

7. InspectionandMaintenanceRoutine inspection and maintenance is important to ensure operation of the OX400 in a good condition. Perform regular inspection and maintenance in accordance with the following instructions.

7.1 RoutineInspectionandMaintenance(1)Checkingreadings

Measure calibration gas about once every two to three months and check the readings. If an error is found with the calibration gas concentration, perform zero-span calibration in the range you use.

(2)Checkinggasflowrate Regularlycheckthesensorgasflowrateinordertomakesurethattheflowrateis200

±25mL/min(afloatershouldbebetweenupperandlowerbarofthe200mL/minbaronflowmeter).

(3)Other Regularly check for signs of malfunction such as strange noises of the pump and fan, or

unusually high temperature of the case. (4)Replacingthefuse BesuretoturnoffthepoweroftheOX400andremove

the power plug from the socket before replacing the fuse. The fuse is installed in the lower part of the power cordplugontherearpaneloftheOX400(seerightfigure).Removethepowercordfromtheplug,pullthefuse holder out of the lower part of the plug, replace the fuse with a new one, and push the fuse holder back in place. Be sure to replace the old fuse with a correctly rated one.

If a replaced fuse burns out soon, the circuit is likely to be defective. Please contact our service department.

7.2 InspectionintheEventofanErrorIf an error occurs, the ERR/ALM lamp on the front panel turns on. An error/alarm code is displayed on the sub-display. If multiple errors occur, codes are displayed in the order of occurrence. Anerrormeansamalfunction,sotheheateristurnedoffandthemeasurementisstopped.When an error occurs, repair is required. On the other hand, an alarm means a warning, so measurement is continued. An alarm occurring during calibration may invalidate the calibration depending on the content of the alarm.The following shows the display and output in the event of an error/alarm.
