 | lower power |
 | sign of well coupled |
| CH: | 3 5900m/s: display the channel and velocity of sound,the instrument has 8 channels to set. |
| 0.0mm: | the current data of measurement |
7，.Measure and operate
| 1，Just put the plug in the socket of main unit and press the “POWER’’key to switch on, there is displaying the last frequency of prob and velocity of sound. |
2，If it is necessary,please choose proper prob and velocity of sound,“CHM”key will help to change the frequency（2M,5M,10M,H2M is avaliable）.While “CHV”key is for changing and choosing the velocity of sound. during the unit is waiting for measurement ,press the“ ”key,then the unit step in o the velocity of sound changing status,velocity can be changed by three buttons(“》”move cursor, “∧”plus 1,“∨”minus 1). |
| 3，Drop the couplant on the sample to be measuresed, couple the probe with the sample.The thickness is display on the screen.If taking the probe away the value wil be keep on ,but the sign of coupling will disappear.Meanwhile, the number of record memoried plus 1(the eighty-fifth record should be changed if records exceeds 85) |
8，Setting upper and lower limit
| The instrument have the upper and lower limit setting function,and if the measurement is above the upper limit or under the lower limit during the operation,there is buzz sound to report. Press “LIMIT”key,the instrument step in o the upper and lower limit setting status.Meanwhile “LIMIT: L”is displaying，which indicate inputting the lower limit.Cooperating with “>>”“∨”“∧” to input the lower limit,then press “ ” to confirm.After this ,the “LIMIT :H”is displaying,the setting is as same as the lower limit.Thus the warning setting is over. |
8.Measure the velocity of sound
| If it is necessary to measure the velocity of sound,firstly,measure the standard thickness of sample by vernier caliper,the mininum thickness suggested is 20 mm.When the unit enter state of readiness,press “>>” to enter state of measurement ,the set operation is as follows: Input the measured thickness (setting method has referenced in the 6th part),and press “ ” to confirm. Couple the probe with the sample, put away the probe after the signal of coupling appears, the screen appers the velocity of sound,meanwhile the current velovity of channel has been replaced by the measurement.. |
9.Two point calibration
| In order to improve accuracy ,the instrument provides two point calibration function, you can choose to use it as needed,when the instrument is turn off,firstly press “”,next press “POWER”, then release "POWER" key before the "ZERO" key, the instruement step in o the two point calibration state. |
| Display: “INPUT:L”:It prompts to input the thickness of the first point,cooperate“>>”,“∨”with“∧”to input the value,then press “” to confirm. |
| Display: “INPUT:H”:It prompts to input the thickness of the second point,cooperating “>>”,“∨”with“∧”to input the value,then press “” to confirm. |
| Display: “CALXXX”:It prompts to sample the first point, couple the probe with the first sample,don’t take away the probe untile the sign of probe displayed. |
| Display: “CALXXX”:It prompt to sample the second point, couple the probe with the second sample,don’t take away the probe untile the sign of probe displayed,after few seconds the instruement finished calibration and turn in o the state of readiness. |
10.Save and check thickness
| The instrument provides saving and checking thickness.It can save 85 value.when measurement is finished ,the thickness saved one by one,the screen displays the number of record memoried.When it over 85 values ,the current result will cover the 85th record. In the state of readiness, use “∧”and“∨”to roll from top to bottom ,then the screen displays the serial number of record and the thickness value at the same time. When the serial number is 85 , press “∧”to display the sign of “NO : 0 ? ”which prompts that whether to zero the memory or not，press “ ” to zero,press any other keys to cancel. |
11，Display the conversion of unit
| The instrument supplies two kinds of unit.When the instrument is in the turn off state ,firstly press “LIMIT” , then press the “POWER”key, and release "LIMIT" key before the " POWER " key, the conversion of "mm or in" finished. the result will saved until the next conversion. |
12. Attention
| 1，The instrument provide 5mm steel board.Using the other samples to measure,you need to drop couplant . Clean sample after used to keep prob from rusting. |
| 2，Alcoho,dilution and so on would corrod the case of instrument,especially the window.During cleaned，you just need to wipe it with a little water. |
| 3，the surface of probe is made of propylene resin ,it is sensitive to the rough surface ,so press it softly . |
| 4，when measured at the ordinary temperature ,the temperature of surface to be measured should not be over 60ºC , unless the probe wil be injured . |
| 5，take care of instrument to avoid damp environment and collision. |
| 6，If the instrument is not used for a long time,you should take out the battery.Unless it may flow the liquid which cause damage to the instrument. |
