2 USE OF CalPman

2.1 INTRODUCTION

CalPman for Windows is an application which has been specially designed to

be used in conjunction with calibrators produced by Eurotron.

When you start, the application acquires all the parameters of the connectedcalibrator which are needed for managing the procedures (referenceinformation of the calibrator), see Figure 2.

If there should be any problems with the serial port, the application will displayan error window and will then start with reduced functions (it will only displayand print reports which have already been created).If there should be problems on the actual serial communication, the applicationwill make a series of attempts before displaying an error window in whichconfirmation of a further attempt or use of the same application with reducedfunctions is requested.

In both case see the paragraph 5. Problems solvinglater in this manual.

Once the reference information (parameters) has been obtained from thecalibrator, CalPman carries out a check of the identification number (license)introduced during installation: if CalPman finds that this number does notcorrespond to the calibrator, it will display an error window and will stop withoutallowing the user to do anything.

If the number and calibrator do correspond CalPman will continue and will allowthe user to carry out all its functions.

Figure 1

_______________________________________________ ___________________________________________________


______________________________________9____________________________________________

Once working, the application will allow the calibrator to be checked by meansof the variable reading, writing and printing commands.

Reading Variables

By pressing this button, or by selecting the Readcommand fromthe Variablesmenu, you enter the Figure 3 shown below

Select the parameter which you wish to read from the calibrator, using themouse, and press the OK button.

Once you have read the parameters you want, you can print themby pressing the button shown here, or by selecting the Printcommand from the Variablesmenu..

Writing Variables

By pressing this button, or selecting the Writecommand from theVariablesmenu, you enter the Figure 4 shown below.Using the mouse, select the parameter you wish to set on the

Figure 2

10/44

_______________________________________________ ___________________________________________________


______________________________________10____________________________________________

calibrator, indicate the value of the parameter in the document boxat the side, or chose it from the available values, and press the OK

button.

CalPman also makes it possible to carry out several automatic procedures; thechoice of procedure to be used depends essentially on the type of operationyou wish to carry out. In this section we make some suggestions about theactivities which can be carried out quickly and extremely efficiently usingCalPman.

Figure 2

8/3/2019 Mm850279-00 Sw Microcal t

11/44

_______________________________________________ ___________________________________________________


______________________________________11____________________________________________

The CalPman application carries out the following tests:

- Temperature probe calibration (Calibration procedure).

- Stress cycles on temperature probes (Probe life test procedure)

- Thermostat inspection tests (Thermostat test procedure).

For each of these three procedures, the application uses information(henceforth called parameters) which the user can input as he likes, as long ashe stays, naturally, within the limits of the program itself.These parameters are then automatically memorized on file on exiting theapplication and are re-read by the same application each time an action ismade, so that they are available each time one of these three tests is carriedout again.When the application is run for the first time, as none of these parameter files ispresent, the application sets this information with default values established byEUROTRON S.r.l.

The files relating to the parameters of each of the three tests are:

LASTCAL.PRC for calibration procedure; it contains parameters forcalibrating temperature probes

LASTPROB.PRB for probe life test procedure; it contains the parametersfor carrying out stress tests on temperature probes

LASTSWIT.PRW for thermostat test procedure; it contains parametersfor carrying out inspection tests on thermostats.

In addition to these three parameter files, containing the last setting carried out,the user can save settings made during use of the application which aredifferent from the default values, in files which he will name as he wishes andwhich he will be able to call up and update at any time. The extension of thesefiles must be the same as the one suggested by the application, and must bedifferent for each test, so that, both the application and the user can recognizeto which test the file in question refers.For example, the probe calibration test settings can be saved by means of theappropriate dialogue box, in a file called PRT100.PRC so that the user can callit up each time a PRT100 type probe has to be calibrated. He can save the

8/3/2019 Mm850279-00 Sw Microcal t

12/44

_______________________________________________ ___________________________________________________


______________________________________12____________________________________________

settings of thermostat inspection tests on IT23451 type thermostats in a filecalled IT23451.PRW.

During one of any procedures is possible to verify the programoperation parameters, setted for the current procedure, by pressingthis button, or selecting the Setted parameters command from theRunmenu

2.1.1 Serial communication

Communication between the PC and the Calibrator is made by means of aserial line; Serial communication parameters are set using the dialogue boxshown in Figure 5, in which the PCs serial communication parameters can beentered. Reference should be made to the technical or instruction manual of the

calibrator itself for information about the calibrator communication parameters.

COM port: is the port that the PC will use for the serial communication with thecalibrator. In this connector will be insert the serial cable furnished with the software

Baud rate: is the serial communication speed that the PC will usedfor the data transfer with the calibrator. The speed hereselected must be the same the speed selected on thecalibrator connected (see the user manual of thecalibrator)

Calibrator address: is the identification number of the calibrator. In a usualconnection between PC and calibrator is always 1; in aconnection between PC and more than one calibrators itcan be a value between 1 and 32. The address here

selected must be the same the address selected on thecalibrator connected (see the user manual of the

calibrator)

2.2 PROBE CALIBRATION PROCEDURE

2.2.1 Description

This type of procedure makes it possible to calibrate probes or thermometers ofany type at various positions previously set in the appropriate dialogue box (seeparagraph 3.2.2 Setting parameters). The values of the test probes can beobtained in two ways: by entering the value manually or completelyautomatically.

The manual method let the user to make calibration of different probes(platinum resistance thermometer, thermocouple, ) because the probesvalues reading is desk calibration free.The automatic method, without MicroCal 200, let the user to make calibration ofplatinum resistance thermometer PRT100 3 wires directly connected to thecalibrator (by the dedicated plug on the calibrator); with the MicroCal 200 ispossible to make automatic calibration of every type of transducers connectableto the MicroCal 200.

2.2.2 Parameter setting

Parameters required for the calibration procedure are set by means of the

dialogue boxes shown in Figure 6. Select the Calibrationcommand from theSettingsmenu and enter the required parameters.

Type of thermostat: this is important information regarding the type of testthermostat

Normally closed: the thermostat opens the contact when theset temperature is reached

Normally open: the thermostat closes the contact when theset temperature is reached

Manual reset: the thermostats operating conditions mustbe re-instated by pressing the re-set button

when the set temperature is reached

Automatic reverse: when this field is selected, the program reduces the timeof the test; when the program checks that the thermostathas ON or OFF, it reverses the rise or fall ramp andproceeds with checking the next point. This condition ispartially valid if a thermostat with manually re-setting hasbeen selected.

Stress cycles: text box in which the number of cycles to be carried out bythe thermostat without obtaining data is entered; themaximum number of cycles which can be set is 99

Measure cycles: text box in which the number of cycles to be carried out bythe thermostat and to obtain operating data is entered; themaximum number of cycles which can be set is 10.

Differential: Text box in which the value in degrees of the thermostatdifferential is entered. Usually this parameter is supplied by

the manufacturer or is printed on the thermostat itself.

Tolerance: text box in which the value in degrees of the maximumpermitted tolerance value of the thermostat switching valueis entered; this number is taken as an absolute value.Therefore, in the calculation, it will be halved and the resultwill be centered on the value (for example, if a switchingtolerance of 4C is entered the permitted switching tolerancevalue is +/- 2C; this means that if the calibrationtemperature is 50C, the thermostat is accepted if it switcheswithin the values of 48C and 52C. The tolerance value isalso usually supplied by the manufacturer).

Differential tolerance: text box in which the value in degrees of themaximum permitted tolerance value of the thermostatdifferential value is entered; this number is taken as anabsolute value. Therefore, in the calculation, it will be halvedand the result will be centered on the differential tolerancevalue (for example, if a differential tolerance of 2C isentered, the permitted differential tolerance value is +/- 1C;this means that if the differential entered is 4C, thethermostat is accepted if it re-set within the values of 3Cand 5C. (The tolerance differential value is also usuallysupplied by the manufacturer).

Rise gradient: Speed at which the set point moves from one point to thenext; it is expressed in C per minute and as a positive value

Fall gradient: speed at which the set point moves from one point to thenext; it is expressed in C per minute and as a negativevalue.

Max temp. limit: a value in C which is added to the values calculated by theprogram referring to the calibration temperature used tocheck for a possible switch outside the pre-fixed limits (forexample, if a switching temperature value of 70C isentered, a switch tolerance of 6C and a maximumexcursion of 5C, the program will take the calibrator up to atemperature of 78C).

Min temp. limit: a value in C which is subtracted from the values calculatedby the program referring to the re-setting temperature(differential) to check for a possible switching outside thepre-fixed limits (for example, if a switch temperature value of70C is entered, a differential of 4C, a differential tolerance
