Page 33: Calibration Input Screen
Click on the Calibration tab in the top left corner (1). You will see the following screen. Calibration Input Screen The Calibration Input Screen (above) is used to monitor and cal- ibrate instrumentation and assign them to specific channels of the HM-5820. The Calibration Input Screen provides a summa- ry of the calibration status of each channel. At this time, verify the calibration information. A green box at the left of a channel indicates that the channel has instrumentation assigned to it and that it is calibrated and ready for use (1). -
Page 34: Units
Each channel has a “Limits On” check box (1). Use the Limits On to keep the machine from exceeding the sensor limits of the instrumen- tation. By selecting this option, before the test can exceed the limits of the sensors, all tests will stop running and the motor will stop to avoid damaging connected instrumentation. Note: An input cannot be calibrated during testing. Units (2) In this field, a calibrated instrument will display the units that were chosen for use at the time of calibration. This field can also be used to automatically toggle conversion of units between lb.-in. and SI units if the need arises. To view choices for types of Units, click on the Units field and the Unit choices will be displayed, see image below. Value (3) This field displays the current calibration value. This value should already be set with 3 decimal point accuracy . If the instrument is not calibrated, the unit will read “N/A”. Clicking on this field will bring up a window where you can enter the required decimal points required for the value. -
Page 35: Performing A New Calibration
Performing a New Calibration The first step in calibrating instrumentation to an input is to remove any calibration that is already being used for that input. To do this, Press the Export Calibration Button (4) (see next page) to select calibrations to export via USB. It is a good practice to export all your calibrations to a thumb drive. In case of a problem this practice al- lows you to recover your calibration data quickly. - Page 36 Once your calibrations have been saved, you will see a pop up screen that says: Calibration Export Successful. To begin to remove existing calibrations, click on the trash can icon (5) to begin to erase the Input calibrations you wish to recalibrate. When you press the trash can icon, this screen will appear. On this screen select an Input calibration to delete, one at a time, and then press the Select button (1). The calibration will be deleted. You can do this for all Inputs you wish to calibrate.
- Page 37 Calibrating your instrumentation to the appropriate Input requires a separate device, which can provide precise and specific loads or displacement, and, which has been certified to be accurate. The cal- ibration process involves plugging the instrumentation into the HM- 5820 while placing the instrumentation into the certified calibration device, which provides a specific set load or displacement. Once this has been done, click the Calibrate button next to the appropriate Input (1). A pop-up window will appear requiring you to enter the password, which is 22234, see below.
- Page 38 Upon fi lling in the password, you will see this screen, Tab 1 Sensor Details of the Calibration settings. On Tab 1, the Sensor Type (1) will default to Volume. For Capacity (2), fi ll in the maximum capacity of the sensor and choose either cm or in . For Counts per Unit (3), refer to the calibration sheet, which came with the instrument you are using and enter it here and then choose mV/V. The next page shows typical calibration sheets with the FS Output information highlighted in orange.
- Page 39 Once this is complete, click on the Right Arrow (4), in the bottom right-hand corner of the screen to save these settings. You will be taken to Tab 2, Limits. On Tab 2, in the Calibration Limit field (1), enter the maximum calibrated limit of the sensor. This value should contain the number of decimal points you require for degree of accuracy, up to 5 points. Limits On (2), should be checked if you don’t want the machine to apply a load greater than the Calibration Limit (1). Calibration Method (3) determines whether this calibration will be based only on the maximum load capacity of the sensor or upon a multi-point curve of up to a maximum of 10 points. If you choose Per FS Output (not a recommended calibration meth- od) it will base your calibration on the maximum capacity of the sensor vs. the minimum capacity of the sensor. If you choose this...
- Page 40 If you choose Multi-Point (Recommended calibration method) Curve and click on the Right Arrow in the bottom right-hand corner of the screen, you will be taken to Tab 3. NOTE: The Volume calibrations will not use a Multi-Point calibration method. Instead, the calibration is determined by using a stepper motor to determine the volume of water currently in the pressure cylinder. On Tab 3 you will be able to set the number of points you want to use for your calibration. You can choose 1-point, 5-point, 10-point or Custom, which allows you to use any number of points up to a total of 10. In the example on the previous screen shot above, a 5-point calibration has been chosen.
- Page 41 Connect the instrumentation sensor connected to a calibrated pres- sure control device, and connect the instrumentation plug to the appropriate channel Input on the back of the HM-5820. You will set the “0” point at 0 with no pressure applied to the sensor. A “5” point calibration will be set with the maximum load capacity of the sensor applied.
- Page 42 On Tab 4, you will be asked to name the calibrated Input. If a user de- fined name is not chosen the machine will save the calibration using a default name based on the sensor type and channel input number. The screen will provide a default name, but you can name the Input anything you’d like. Once you’ve named the Input, click on the disk icon in the lower, right-hand corner (1).
