1. U se gra ph fo rmats Show the measuring result Importance of using the right sensor name For graph formats to function different measuring objects must use the same sensor names If for example you measure 3 phase current on a series of measuring objects you can name the phases L1 L2 and L3 on each object In other words the same name Alternatively you can let WinLog name the sensors automatically and they will automatically be named G1 G2 and so on You need to ensure that the sensors are connected in the same way from measurement to measurement so that the phase one will always be L1 phase 2 L2 etc Later during graph composition you create a graph that collects data from L1 and so on Using the I variable described below you can manage the header text and collect information from the measuring object You have now created a general graph that can be used for different measurements Using the I variable If you change object during analysis and thereby collect measuring data from another measurement possibly made at another geographic location you will most likely want the headings and other information to be changed automatically The variable I is used for this purpose Wherever l is used in the graph s text box Monitor will go into the current object and replace I with the text information entered by the user when the measuring object was defined The variable exists in an array of forms with s
2. HORIZONTAL and VERTICAL grid lines are optional HOW SHOULD THE GRAPH LOOK In the middle section of the dialog box there are options regarding the appearance of the graph In the upper box you can enter RESOLUTION which is simply the curve s thickness on the screen This applies only if you have previously selected the Graph type Curve Consider that the thicker the curve you select the more measuring values are hidden behind each colour spot a curve consistes of a number of dots so near each other that they merge Monitor keeps track of how many measuring values a spot contains and calculates a median value of all Then the spot is drawn in the place where the median value should be This means that the thicker the line higher resolution you choose the more smoothed out the curve will become In the lower box you can select the width of bars in a BAR CHART Enter any number in the left box and from the drop down list select a width from second to year Monitor will calculate a mean value for the selected time period and position the top of the bar at this point The appearance of the bar pattern colour etc is selected from another dialog box connected to the graph refer description below BUTTONS TYPESTYLE and COLOUR can be freely selected using the standard Windows approach The COLOUR ON X AXIS selects the colour of the time display while COLOUR selects the colour of the grid Tip If you wish to hide the

This means that if current is 0 995A for example it is presented as 955mA If it reaches 1001A it is presented as 1 001kA Sl prefix U Object Sensor Unit When U is written in the text Monitor will look up the type of Sensor under Object and use that instead You can leave out the Object name and enter just the sensor name Information will then be collected from the object that was selected using the object button If you leave out both the object name and the sensor and in addition use SI earlier in the formula the Sl unit will be displayed and you then need to manually indicate the type using text Example F CURRENT MIN U CURRENT Will be displayed as 3 102 A if the minimum value was 3 102 l Index Object Info When l is written in the text Monitor will look up text information about the measuring object and display it The text information has been previously entered during Composition of the measuring system Index is a digit from 1 to 5 You can leave out the object s name in which case the object selected with the Object button will be used Example l 3 Read the text in info box 3 found under Measurement system configuration If you enter only l you get the current object s name M Object Sensor Measurement When M is entered in the text Monitor will look up Data record information for the correct Object and Sensor Data record information is the text you enter in Measure

5. Battery life time It is important to check power consumption A modern battery driven logger should not consume more than 0 1mA in standby position During measuring it may consume considerably more approx 30 40mA Note that short registration intervals 1 30 seconds significantly increase consumption Input signals You have maximum flexibility if you select an instrument with universal inputs You can connect different types of sensor directly using the appropriate cable and connection Some loggers require external signal transducers to scale the sensors Consider that these generally use a lot of power and also take up a lot of space An important aspect is the power supply to the sensors If an external power supply is needed there is the inconvenience of extra cables Quality loggers have a built in supply directly via the sensor cable Watch out for the power consumption here A humidity sensor for example can flatten a 9V battery in 24 hours if connected the entire time Select a logger that can control the power supply to the sensor Accuracy Many suppliers do not differentiate between resolution and accuracy and yet they are actually two different things The resolution indicates how small the parts of the signal are that can be identified Many suppliers have for cost reasons only used 8 bits and this provides a resolution of 1 256 With a measuring range of for example 300 C 572 F this means a resolution of

8. 33 How and where data is saved Measuring and data collection How and where data is saved Measuring data is saved automatically when it is collected and no special action is required Transfer from instrument to PC is made using a secure communications protocol that has self correcting functions If no error message is received you can be sure that the measuring data has been saved correctly Data format The user sees data saved in a measuring object where each sensor has a name The data can be studied by composing a graph and indicating the current sensor name and measuring object If you study the hard disk using Explorer or similar you will see the program s internal data structure Folders for measuring objects Measuring data is saved in the directory shown under Options and Setup In this directory each measuring object is assigned an individual folder with the object s name For example the measuring object HUS318 will have a folder with the name hus3 8 dat Files for measuring data The folders contain measuring data for the sensors associated with the object Each sensor has its own file For example a sensor with the name LEVEL_7A will be assigned the name evel_7a The folder also contains a file with information about the measuring object The file is given the name setup dat This file name occurs in every folder with measuring data ie one for every measuring object Measuring data in the sensor
9. Graphs are assigned sequential numbers when they are created refer Graph dialog This number is used in Text formula eg GRAPH 1 or GRAPH 4 By using the GRAPH object in the text formula you can make calculations faster during analysis and simplify input during composition Formula such as TEMP1 TEMP2 will not always give the required result when they are used in text formula Individual values can be for example from different times clock stamps and this means the calculation will not work In such cases a graph can be created with the formula TEMP1 TEMP2 The graph s number is then used in the Text formula instead of the direct calculation The GRAPH object is simply an interim step in the calculation If the modifiers refer Variables MAX or MIN are used in the GRAPH object eg GRAPH 1 MAX you can also get different maximum and minimum values depending on how much you have zoomed in in the graph The values provided represent the visible maximum and minimum in the graph If you require an absolute maximum or minimum the sensor s name should be used directly in the calculation eg TEMP MAX mitec Monitor 83 Calculations and formula MORE THAN THESE FOUR CALCULATION METHODS Show the measuring result Variables and constants are not sufficient to build a complete formula You also need calculation methods such as plus minus square etc In WinLog s Formula language we have divided these into O
