DMM VIEW Minimum System Requirements Operating System: Windows 98/NT/ME/2000/XP Graphic Card : Screen Resolution 800x600 over 256 Colors Digital Multimeter : MAS-343/MAS-344/MAS-345/M9803R 1. Icons 1-1.Configuration Model selection MAS-34X : MAS-343/MAS-344/MAS-345 M9803R : M9803R Port selection (RS232C port selection:COM1,2,3,4) Sample selection Repetitive : data sampling until "Stop" set Count : data sampling upto the pre-defined count number Maximum count is 9999. Interval (Interval time set for catching a data) Auto : sets interval time automatically for 1 second. Manual : sets interval time for 1 second to 3600 seconds. Comparison Function A short alarm sounds whenever the input values meet the buzzer condition. Low : sets low limit value between -9999.9999 and +9999.9999. Hi : sets high limit value between -9999.9999 and +9999.9999. Low limit value must be less than high limit value. Note : This comparison function considers the unit of the first input value since any buzzer condition is set from "Off" as its reference unit. Buzzer Condition For alarm sound, Basic Alarm sound needs to be set "ON" on the sound control board. Off : Buzzer off Low < and < Hi : Buzzer beeps when the input value is between the low limit and the high limit Low > : Buzzer beeps when the input value is under the low limit. Low > or > Hi : Buzzer beeps when the input value is under the low limit or over the high limit Hi < : Buzzer beeps when the input value is over the high limit. Temperature Selection for MAS-34X series Select temperature type : Celsius or Fahrenheit. Independently of the meter, any type of the temperature can be converted into each other. For example, Fahrenheit degree will be displayed on the screen with Fahrenheit selected while the meter measures Celsius. Graph mode selection Auto : sets Vertical reference of graph automatically according to the DMM measuring range. When "Auto" is not chosen, set the vertical value manually in the sections of Y.Min and Y.Max. After that, first input value's unit is used in the following graphic. In non-auto-graphing mode, curve draws out of the graphic area when the input value is over the Y.Max vaule or under the Y.Min value. Note : For getting the best graphic, proceed the next step. - Set the Range Hold on the meter. - Clear Data on the screen. - Define Y-Max and Y-Min on the Configuration menu. - Start. Grid set X-grid : draws x-grid on the graph Y-grid : draws y-grid on the graph Color sets the colors of grid lines and current position bar (cursor) on the graph. 1-2. Clear data Clear all data on the display. It should be done when the measuring mode of the meter is changed for getting a proper graphic. 1-3. Start Start receiving data from the connected meter. 1-4. Stop Stop receiving data from the connected meter. 1-5. Load data Load the saved data file. It lists files whose extention is "xxx.dmm". 1-6. Save data Save the displayed data in a specified file. Its extention file name is "xxx. dmm". 1-7. Save as Excel Save the data sheet in an Excel format file. Its extention file neame is "xxx.csv". 1-8. Print data sheet Print the data sheet of all data recorded. 1-9. Print graph Print the graph on the display. Select required print-part on the display using horizontal scroll bar or zooming mode before printing. 1-10. Help display Readme.txt. 1-11. Exit exit the program 2. Display 2-1. Value & percentage display It displays input value,maximum, minimum values and percentage value which is input value's percentage to the vertical maximum value. 2-2. Data sheet It lists input data values and data input time. 2-3. Graphics It draws graphic curve of input values. Vertical axis can be specified by Y.Min and Y.Max. When it is in auto-ranging mode, the Y axis is defined automatically. Horizontal axis is the number of data sheet. This display is enlargable with the enlargement icon and movable by horizontal scroll bar. Specified part of the graph can be zoomed in by making window from left-upper point to right-down point dragged with mouse during its left key pressed. To return back to the original display, drag the mouse with left key pressed inversely from right-down point to left-upper point making a window of any size and anywhere on the graph screen. And, in auto-graphing mode, hidden upper graphed or lower graphed part can be shown by using the center ball of mouse. But, the graphic function has limits in auto-ranging mode. So, set range hold on the meter or input manually Y-axis values for a more safe graphic. 3. RS232C Interface protocol 3-1.
