Instrument Setup Software for Series 1 Laureates

Digital Panel Meters, Scale Meters, Counters, Timers, and 6-Digit Remote Displays.

Applicability

This web page describes Laurel's Windows-based Instrument Setup software when used with Series 1 digital panel meters, weight / scale meters, counters, timers and remote displays, which were shipped prior to mid-2007. The software recognizes these legacy products and bring up the appropriate computer screens, which are somewhat different than the screens for Series 2.

Setup Overview

Setup of the Laureates entails the placement of plug-in jumpers to set ranges at the hardware level, followed by programming. Programming can be in three ways:

  1. From a computer running Instrument Setup software and connected to the instrument via RS232.
  2. From the instrument front panel as guided by Instrument Setup software, with no connection to the instrument via RS232.
  3. From the instrument front panel using the printed user manual and no computer assist.

Method 1 is the easiest and makes full use of the graphical user interface (GUI) provided by Instrument Setup software. When the computer is connected to the instrument, the software recognizes the type of instrument and only brings the appropriate screens and menu choices. Clicking on any item brings up a detailed help screen for that item. Setup files can be retrieved from the instrument or from disk. Edited setup files can be downloaded into the instrument (and be saved to disk.

DPM & Counter Calibration

Click on any of the reduced screens for a full-size screen view, then click on the Back button of your browser to return to this screen.

For absolute calibration, the Laureate must be connected to an external standard and to a PC running Laureate PC Setup & Calibration Software. The initial step is to establish serial communications between the PC and DPM or counter, as described for DPM setup. (Special calibration software is required for Laureate temperature meters and DC, strain or loadcell meters used in ratiometric bridge mode, as described in a separate calibration page and software download page).

DPM Calibration Main Menu Screen

From the Main Menu screen, click on Calibration on the top menu bar. The software will recognize the type of Laureate DPM (DC meter, True RMS, load cell meter, scale meter, or temperature meter) and bring up the appropriate calibration screen.

DC Signal Conditioner Calibration Screen

The DC Signal Conditioner Calibration screen is an example of a Laureate DPM calibration screen. It prompts the user for each range to be calibrated, displays the required jumper settings, and prompts for the signals to be applied from an external calibrator. Click on the screen to the left for additional details.

Frequency Meter Calibration Screen

Calibration of the quartz crystal of the Laureate counter with dual-channel frequency signal conditioner requires the input of a known frequency from a calibrator. Apply the frequency, then enter the frequency in Hertz. Calibration will be automatic, with storage of the calibration factor stored in non-volatile memory. Click on OK to exit.

Other Online DPM Operations

If you have a serial connection to a Laureate DPM or counter, you can perform a number of online operations from your PC.

Setup File Selection Screen for Panel Meters

Under the DPM pulldown, menu you are given the opportunity to Get Setup (or retrieve) setup data from a DPM, or to Put Setup (or download) setup data back into the nonvolatile memory of the DPM. The same setup file stored on disk can be downloaded into multiple Laureate instruments, greatly speeding up setup in a production environment.

Commands Screen for Digital Panel Meters

Under the Commands pulldown menu, after you have performed a Get Setup operation, you can command functions by using the computer mouse. You can reset individual meter functions, display current or peak readings, and enter numbers to be displayed remotely by the DPM. For the remote display, the first position must be a blank, + sign or - sign.

Graphics Output Screens of Digital Panel Meters

Under the Readings pulldown menu, you can select three formats to display the DPM data on the computer screen:

  • List presents the latest readings in a 20-row by 10-column table. Press pause at any time to freeze the display. This is one method to capture peak readings.
  • Plot generates a plot of readings vs. time in seconds. It effectively turns the DPM-PC combination into a printing digital oscilloscope.
  • Graph generates a histogram where the horizontal axis is the reading and the vertical axis is the number of occurrences of readings. The display continually resizes itself as the number of readings increases.
