Martel Electronics DMC-1400 Documenting Multifunction Calibrator

Martel Electronics DMC-1400 Documenting Multifunction Calibrator

We call this “the documenting calibrator for the rest of us.” Work better — get better work. Set up and calibrate any instrument as you normally would. Just press the “SAVE” key after each calibration point. When you complete the calibration, follow the prompts to enter the “tag” information and you are DONE.

The DMC-1400 also features the ability to test for pass/fail criteria, capture both AS FOUND and AS LEFT data, maintain calibration data for 50 instruments in nonvolatile memory, and even print calibration certificates right in the field, with no PC needed, using our optional OTS-100 portable certificate printer.

Measure and simulate thermocouples, RTDs, current, voltage, frequency and pressure, and source pulse trains with one lightweight easy to use calibrator. A communications port compatible with BetaPort–P pressure modules is provided, as is an isolated milliamp/Volt read-back circuit. Arrow keys, direct numeric keypad entry, and three software-driven function buttons, plus a large backlit, menu-driven graphics display combine to provide a highly intuitive, simple yet powerful operator interface.

• Measure and simulate T/Cs (13 types), RTDs (13 types), Ohms, current, voltage, frequency and pressure;
  source pulse trains

Measuring Pressure with the DMC-1400

The DMC-1400 is compatible with BETA pressure modules, with the use of an adapter.

The Documenting Function

Adding documenting to your normal workflow is easy. Before you start a calibration, simply choose document from the calibrator operating menu. Then choose the calibrator input and output types. A neat feature is that you can also choose “manual” for either or both input and output.  That allows you to calibrate and document virtually anything. Connect the calibrator to the instrument you’re testing and use it as you normally would. After each calibration point, just press the SAVE key. When you’re done, press the DONE key.

The calibrator will then prompt you to enter tag and instrument data, technician ID, ambient conditions and so on. Save that and you have completed the “as found” part of your test. You can also choose to have the calibrator evaluate the pass/fail status of the instrument by supplying an allowable error tolerance in terms of the full scale performance of the instrument. If the instrument passes, you can choose to copy the as found data to the as left data, and you’ve completely documented your calibration.

If you need a calibration certificate right now, connect the DMC-1400 to our portable battery operated OTS-100 printer and print the certificate. Easy and DONE.

When the day’s work is over, you can save the data to a PC. A Windows® PC already has most, if not all, of the software you need.  If you will just print calibration certificates, use Windows HyperTerminal to upload an ASCII image of the certificate and print away.  With a Microsoft Excel compatible spreadsheet, you can choose to upload .CSV files using the free Martel USV (Upload-Save-View) support utility. USV will even organize your calibrations in subdirectories to keep your data in easy to fi nd and retrieve status. With the DMC-1400, it’s all you need to have a complete and organized, paperless, calibration system.

The Martel USV Utility

The Martel USV (UPLOAD SAVE VIEW) Utility program manages the valuable data captured during calibrations and stored in the calibrator by allowing the viewing of data on the computer and uploading it in a choice of formats. It even creates a simple file cabinet of directories and files so it’s easy to find the data you need once it’s on the PC. Martel USV is freely distributed with the calibrator or it can be downloaded from (www.martelcalibrators.com).

Martel USV is simple to use, with a clean and straightforward interface, allowing ready access to all the functions needed.  USV is run by selecting it from the normal Windows start menu. It loads instantly, ready to get data from the DMC-1400 calibrator.  The first time USV is run, an RS-232 COM port will need to be selected from within the utility to establish communications with the DMC-1400. This only needs to be done once unless a different COM port is used.  Report styles to be uploaded to the PC from the DMC-1400 can be chosen from either text (.TXT) or comma delimited (.CSV) files. Text files are an image of the calibration certificate, which can be printed using Windows®™ Notepad® or other text editor. The CSV file imports right into Microsoft Excel® or other similar spreadsheet program or database.  Once a type of file upload has been chosen, that type becomes the default unless changed at a later time.

Some other useful confi guration options for the USV are the size of the window, which can be made any size up to full screen.  USV remembers this from one session to the next. The location of data files that are saved from the calibrator can also be selected and this becomes the default location until changed. The location can be a local folder or a network location. The default location is the user’s My Documents folder in a directory called Martel USV Reports.

Tags can be individually selected for uploading. To upload more than one tag at a time, the Control or Shift keys are used to select multiple tags using the normal Windows conventions. Alternatively, all tags can be uploaded at once using the menu selection “Reports” and selecting “Upload All Tag Reports.”

Files can be saved in several confi gurations:

• Save Reports as a Single File …
• Save Reports as Separate Files …
• Save Reports in Separate Tag Directories…

   

The most powerful of these options is to Save in Separate Tag Directories, which creates a virtual file cabinet with a folder for each TAG. As calibrations continue and each TAG is calibrated multiple times, the data for these calibrations will be stored in the same tag directories. Each TAG data file name identifi es the TAG ID and date and time of calibration, so it’s very easy to keep things organized and sorted out without using an extensive, expensive, and challenging database management program. On the fl ip side, if you do need to use a powerful calibration management tool, CSV files uploaded from the DMC-1400 can be easily imported into your database in most cases. By using Microsoft Excel, the CSV file can be used to create any type of custom calibration certificate or report needed.

A few of the other useful functions of the USV program are to clear the calibrator’s memory of no longer needed calibration files. You can also open saved files from your hard drive for quick and easy viewing.
