Please note - ALL stored data will be deleted. Storage The Storage option sets the default for data storage. It may

2、be set to always store data or never to store data. Highlight the desired option at the bottom of the screen and press Enter. With the exception of tests carried out in Continuous mode, at the end of each test you have the option to change the default by selecting STORE or NO STORE at the bottom of

3、the results screen. At the end of a test, if memory is full this STORE / NO STORE message will change to MEMORY FULL and no more tests will be stored. Data is stored indefinitely if a charged battery pack is fitted. If the main battery becomes exhausted or is removed, data is maintained for a period

4、 of 4 days by an internal backup battery. When a charged battery pack is refitted, the backup battery will recharge to full capacity within 1 week. Range Menu DLRO 10X uses a test current between 100 A and 10 A to measure the resistance of the item under test. If set to AUTO, DLRO 10X will select th

5、e current according to the resistance it detects. (see Specifications, Ranges) However, in some cases it may be desirable set a maximum test current. If this is so, move the cursor to the desired current and press Enter. Six test currents are available; 10 A, 1 A, 100 mA, 10 mA, 1 mA and 100 A. Sele

6、cting the 10 A maximum will have the same effect as selecting AUTO. The Main Menu screen will show the active current range beneath the RANGE heading.

7、the end of each test, (with the exception of a test in Continuous mode), you can select the STORE or NO STORE option to store the test results or not. Select the desired option using the cursor control. This overrides the default setting under Options, Storage for one test only. If you wish to add c

8、omments to the test results, instead of pressing Enter, briefly press one of the twelve keys on the keypad. You will enter a memo screen that allows you to enter up to 200 characters of alphanumeric information concerning the test. When you have entered all information press Enter and the measuremen

9、t and memo will be stored regardless of whether STORE or NO STORE was selected. If you do not wish to add notes and are happy to accept the default STORE / NO STORE setting you may press the Test button and a new test will be started. TEST RESULT STORAGE Each test is numbered, starting at test 1. Th

10、is test number is incremented automatically, as each result is stored. The test result memory can store a maximum of 700 tests, each being identified by its test number, date and time. It is advisable to retrieve all data to a PC and then to delete all data before the test number reaches this maximu

11、m. Deleting the data will reset the test number to 1. This will save loss of data. KEYPAD OPERATION The 12 key keypad is similar to those used on mobile telephones in that each key is capable of producing one of several characters depending on the number of times the key is pressed. The keypad is us

12、ed to enter data into the Memo field. Pressing the blue key marked 9/A changes the function of the keyboard between alpha and numeric modes. In alpha mode a full height flashing vertical bar (|) indicates the cursor. The keys 2 to 9 will produce the letter shown on the keys depending on the number o

13、f presses. For example if the 2 key is pressed once an A will appear, twice and a B will appear etc. The 0 key produces a space. The 1 key is a destructive backspace. In numeric mode a half height flashing bar () indicates the cursor. The keys marked 1 - 9 and 0 produce that number when pressed. Pre

14、ss the respective key briefly to enter the desired number. Pausing will cause the cursor to move on to the next character. If a key is held down it will auto-repeat. The key at the bottom right hand corner of the keypad marked with a dot is a special key that produces 20 special symbols. Each press

15、will sequentially produce the character shown on next page: GENERAL OPERATION DLRO 10X 10 .Decimal point or full stop Ohms symbol mlower case m (abbreviation for milli) Symbol for micro #Symbol known as hash or pound and commonly used as shorthand for number %Percent sign (Left round bracket )Right

16、round bracket -Hyphen, dash or minus sign / Slash :Colon at symbol; Tick mark !Exclamation mark ?Question mark $Dollar symbol =Equals sign Greater than symbol *Asterisk GENERAL OPERATION DLRO 10X 11 TEST MODES DLRO 10 has 4 test modes which are selected by repeated presses of the Mode button. At the

17、 end of each test, DLRO 10 will display the average of the values obtained with forward and reverse current. DLRO 10X has 5 modes. On DLRO 10X these modes are selected from the TEST menu using the cursor control and Enter key. At the end of a test, DLRO 10X will show three resistance values; that ob

18、tained with forward current, that obtained with reverse current and the average value. Normal mode Normal mode makes a single measurement of the resistance of the sample using forward and reverse current Please note that in this mode both the current and voltage leads must be connected across the te

19、st sample before the Test button is pressed. To make another measurement, ensure the test leads are connected and press the test button. Automatic mode If Automatic mode is selected, your instrument will remain in a state of readiness waiting for both the current AND voltage measuring leads to be co

20、nnected to the test piece. When this is done, a forward and reverse current test will be started automatically. To make another measurement simply break contact with the test sample and remake contact. For example, if measuring joints in a long bus bar, you may leave the current circuit connected at

21、 opposite ends of the bus bar. Simply making contact with voltage probes across the joint(s) you wish to measure will then activate the measurement. Continuous mode Continuous mode requires the connections to be made before pressing the Test button. Your instrument will then repeat its forward and r

22、everse measurements and display the results approximately every 3 seconds until contact is broken or the Test button is pressed. Inductive mode DLRO 10 and DLRO 10X are able to make d.c. resistive measurements on loads that exhibit an inductive component using the test mode indicated by the inductor

23、 symbol on the DLRO 10, or by using the inductive mode on the DLRO 10X. When measuring inductive loads it is essential that the current carrying leads are securely clamped to the item being tested and that they are not removed before any stored charge has been discharged at the end of the test. Fail

24、ure to comply with these instructions might result in an arc being produced, which might be dangerous for the instrument and the operator. Having selected inductive mode, connect all four leads to the item being tested and press the Test button. DLRO will check that all four leads are in adequate co

25、ntact with the test piece and will then apply a test current and try to find the correct range. The display will show 1 - - followed by 1 - - - -. During this time you may see the current range increasing or decreasing. On the DLRO 10 the “I” lamp will flash and the message “Current Flowing” will ap

26、pear on the DLRO 10X display. After a short time resistance readings will appear on the display, reducing gradually over aperiod of time until eventually a stable reading will be obtained. The time required for a stable reading may vary from a few seconds up TEST MODES 12 to several minutes dependin

27、g on the inductance and resistance of the test sample. There is no time limit for the inductive mode test, which will continue until the operator presses the Test button. When the test is terminated, the “I” lamp will remain illuminated on the DLRO 10 or the message “Discharging” will appear on the

28、DLRO 10X display until any stored energy has discharged. When these messages are extinguished it should be safe to disconnect the “C” leads. However, the discharge indicator is an active electronic device and should not be relied upon. You should observe your organisations operating procedures. At t

29、he end of the test both instruments will display the measured resistance, the DLRO 10 will flash the relevant current lamp while the DLRO 10X will display the test current used on the display. Please note:- In inductive mode the 10A test current will not be used. Undirectional mode On the DLRO 10X o

30、nly, this mode makes the measurement as in automatic mode but using forward current only. This mode speeds up measurments on samples that are known to be free of any standing voltages or thermal emfs. However the accuracy of the reading may be degraded by any thermal emfs but should not be worse tha

31、n 0.2% 30 digits. Since current is only applied in the forward direction, in this mode only a single resistance value will be displayed. A test may be repeated by breaking contact and reapplying the test probes or by pressing the Test button. Test Modes 13 TESTING USING DH4 DUPLEX HANDSPIKES Each ha

32、ndspike is marked with the letter P. This indicates the potential terminals. These should be the inside contacts when making a measurement (as shown in the next section Testing Using Duplex Handspikes or Individual Leads). One of the DH4 handspikes is fitted with two lamps marked L1 and L2 and an ex

33、tra lead. This lead should be plugged into the 4 mm socket next to the main terminals on the right hand side of the instrument. These lamps provide information to the operator, which would otherwise only be available on the instrument display. The meaning of these lamps is described below. For examp

34、le, using the DH4 Duplex Handspikes with the DLRO 10 in AUTO test mode: 1.Press the TEST button on the instrument. 2. Lamp L1 will illuminate a continuous red to indicate contact failure. See the instrument panel for details if required. 3. When all four contacts connect, L1 will extinguish. 4. No l

35、amps will show during the test unless contact fails. 5. Lamp L2 will light a continuous green when current flow has decayed to less that 1 mA to signal end of test. 6. Removing the probes will extinguish the green L2 (end of test) and Light the red L1 (no contact). Since your DLRO always ensures goo

36、d contact before applying the full test current, there will be no splash to erode the contact tips. However, should the tips become worn or blunted, they can be simply replaced by pulling out the worn tips and inserting new ones. TESTING USING DUPLEX HANDSPIKES OR INDIVIDUAL LEADS. Connect the four

37、leads as shown. If using Duplex Handspikes ensure that the probe marked P is inside the C probes. TEST TECHNIQUES la rponse par dfaut est NON.
