Introduction This manual contains information for servicing YOKOGAWA’s DX1000, DX1000N, and DX2000. WARNING This service manual is to be used by properly trained personnel only. To avoid personal injury, do not perform any servicing unless you are qualified to do so. Refer to the safety precautions prior to performing any servicing. Even if servicing is carried out according to this service manual, or by qualified personnel, YOKOGAWA assumes no responsibility for any result occurring from that servicing.
• Do Not Operate in an Explosive Atmosphere Do not operate the instrument in the presence of flammable liquids or vapors. Operation in such an environment constitutes a safety hazard. Prolonged use in a highly dense corrosive gas (H2S, SOx, etc.) will cause a malfunction. • Do Not Remove Covers The cover should be removed by YOKOGAWA’s qualified personnel only. Opening the cover is dangerous, because some areas inside the instrument have high voltages.
Overview of This Manual This manual is meant to be used by qualified personnel only. Make sure to read the safety precautions at the beginning of this manual as well as the warnings and cautions contained in the chapters relevant to any servicing you may be carrying out.

Chapter 1 Principles of Operation 1.1 Principles of Operation 1 Principles of Operation The following explains the principles of operation of the DX.
1.1 Principles of Operation Saving Data The capacity of the internal memory is either 80 MB (standard memory) or 200 MB (expansion memory). The CF card can be used as an external memory medium. Display/Keys/Easy Text Entry The DX uses an LCD display. You can control the DX with key operations. With Easy Text Entry (optional), you can control input by the remote control terminal.
Chapter 2 Troubleshooting 2.1 Failure Analysis Flow Chart 1 When a failure occurs, refer to the flow chart below for corrective actions. 2 Troubleshooting Doesn’t function at all (nothing is displayed) 3 Is the power switch* ON? Does the switch operate normally? NO Turn the switch ON correctly. 4 YES Is the power supply wired correctly? NO 5 Wire it correctly.
2.1 Failure Analysis Flow Chart Keys do not operate correctly Is the key lock set? YES Release the key lock setting. NO See No. 4 of the checklist. If there is a problem with a display screen or other function Have measures against external noise been taken? NO YES See No. 2, 3, 7, 9, and 10 of the checklist in section 2.2. • Keep measurement input, communication, and other wires and cables away from noise sources. • Be sure to ground all instruments.

Chapter 3 3.1 Testing Acceptance Test 1 This section describes the procedure to perform the acceptance test. 2 1. Read the preface to the user’s manual, “Checking the Contents of the Package” and verify that you have all of the contents. 2. Make sure to understand the operating procedures as described in the user’s 3 3. Check each function using the user’s manual. Testing manual. 4. Read and implement section 3.2, “Self Diagnostic Test.” 4 5. Read and implement section 3.3, “Performance Test.
3.2 Self Diagnostic Test The DX is provided with complete self diagnostic functions to enhance reliability in measurement and serviceability. When you turn ON* the power, the DX will automatically execute the following types of diagnoses alternately and display the results. After these tests are completed, the recorder is ready for use. * The DX1000N power supply switch is located inside the bezel.
3.3 Performance Test 1 Read the warning and cautions below before beginning tests. 2 Test Environment Item Ambient temperature Relative humidity Atmospheric pressure Power supply frequency Power supply waveform DC power supply ripple Vibration Position Interference*1 Electrical field Magnetic field Atmospheric pollutants Other external effects*2 *1 Interference refers to common mode noise, series mode noise, power supply noise, and other phenomena in the signal line.
3.4 Test Procedures Insulation Resistance ● Test Procedures Perform a measurement with an insulation resistance meter and check whether the results satisfy the reference values. Perform the measurement with the power switch turned ON.
3.4 Test Procedures Withstand Voltage 1 ● Test Procedures Perform the test with a withstanding voltage tester, and check whether the results satisfy the reference values. Perform the measurement with the power switch turned ON.
3.4 Test Procedures Measurement Accuracy ● Overview The measurement accuracy is tested using two different* integral times. * But only one integral time is used when using the DX2000 with the /MC1 option. The measurement accuracy test is performed in one of the following ways. • One representative channel for each A/D converter is tested, and the channel-tochannel error between the representative channel and other channels is tested (see next page).

Chapter 7 7.1 Replacing Parts Introduction 1 This section describes replacing parts necessary for maintenance and repair. Replaceable Parts 2 When it becomes necessary to replace parts, it is recommended to replace entire assemblies rather than specific parts within assemblies. If you plan on replacing parts yourself, please refer to the Customer Maintenance Parts List (CMPL) in chapter 6 for a list of parts supplied by Yokogawa. Parts not on this list are not available through Yokogawa.
7.2 Recommended Replacement Periods for Worn Parts To preserve the reliability of the DX and to use the DX in a good condition for an extended time, it is recommended that periodic replacements be made on parts. The replacement parts may change to accommodate preventive maintenance over extended time. Be sure to check with your nearest YOKOGAWA dealer. The following table shows the recommended replacement period for expendable parts.
7.3 Notes Pulling Out the Inner Instrument (DX1000N) 1 This section explains how to pull out the inner instrument. Refer to these instructions as well when reinstalling. 3 WARNING • When reinstalling the inner instrument, check that no foreign objects are inside the case, that the connector pins are not bent, and that no other abnormalities exist. These can be causes of fire, electric shock, and damage to instruments. • Always turn OFF the power switch when pulling out the inner instrument.
7.3 Pulling Out the Inner Instrument (DX1000N) Testing If the DX hardware style number is 1, perform the tests below (see chapter 3) after reinstalling the inner instrument. The hardware style number is printed on the name plate. The name plate is on the top of the case (outer side). MODEL STYLE H S SUFFIX Hardware style number SUPPLY FREQUENCY NO.
