AEMC L320 Simple Logger Instruction Manual

AEMC L320 Simple Logger

IMPORTANT NOTICE BEFORE OPERATING
A scale must be set prior to saving a downloaded DC Logger file for the logger to function correctly

To create scales with the Logger connected
The first time a DC logger is used with a fresh install of the Simple Logger software a scale must be set for each different DC logger model. Once a scale is set for a specific model, the software will default to this scale each time that model is connected. To set a scale for the model in use, connect the logger and a Scale menu will appear. Click on Scale and the scaling window for the model used will appear. From the scaling window, you may set a custom scale or open a predefined scale from the File-Open menu. The predefined scale is in the directory for the Simple Logger software.
To create scales without the Logger connected
Go to Scaling from the File menu and select the range for the model used. From the scaling window, you may create a custom scale and save it using the File- Save Command. The predefined scales are saved in the directory for the Simple Logger software.

• Remove the logger from the circuit under test and transport it to the computer for data downloading. See the User Guide on the CD-ROM for downloading instructions.

Using the Software
Launch the software and connect the RS-232 cable from your computer to the logger.
NOTE: A language will need to be selected upon the first launch.

Select Port from the menu bar and select the Com port (COM 1, 2 3 or 4) you will be using (see your computer manual). Once the software automatically detects the baud rate, the logger will communicate with the computer. (ID number of the logger and number of points recorded displayed). Select Download to display the graph. (Takes about 90 seconds.) Select File from the menu bar, then Scaling and the Range of your logger.

Scale and Engineering Unit Programming
The Simple Logger® Models L320, L410, and L430 allow the operator to program the values for scale and engineering units from within the software. This permits the user to display the recorded data on the graph or in the tabular listing directly, in the units appropriate to the measurement, rather than mathematically converting a voltage or a current to the proper scale and value after the graph is displayed.
Scales can be programmed from two locations in the software:

• File menu option: Use this option to create a library of scales to use with DC voltage and DC current loggers. This will allow the user to select a number of predefined scales.
• Scale menu option: Use this option to create scales for loggers connected to the serial port for downloading.

The Simple Logger® software allows the operator to define up to 17 points along the scale for DC current measurement and up to 11 points for DC voltage measurement type loggers.
Any combination of points may be used to create the scale, which allows the user to plot both linear and non-linear data. (See Figures 2 and 3).

Creating a Library of Scales

• Select File and then Scaling from the main menu.

• Select the type of logger to be scaled from the choices presented.

• A window similar to Figure 4 will appear as soon as you make your selection. This window shows the programmable scale points and the programmable units field. The left screen provides the scale and unit programming, while the right side displays the profile of the programmed scale in relationship to the actual input to the logger.

• Scale values entered here will not effect the current graph, should one be on the screen. This window is strictly for creating templates to be used at a later date with newly downloaded loggers.

• Creating and storing the scales and units here will save you time later on, especially for frequently used scale settings.

Two buttons are available from within this window:

• Clear All button: This will clear all scale numbers entered and any units entered allowing you the opportunity to start over again.
• Close button: Returns to the main menu without saving the data.

Perform the following steps to create a Template

• Click in any of the blank slots and type in a number (up to 5 characters) to enter a scale value. The minus sign and decimal point can be used as valid characters (e.g. -10.0 would be a valid 5 character number). As you enter numeric data in the scale slots, the scale profile will appear on the small graph in the right side of the window. Both linear and non-linear profiles are acceptable.
• Once the scale is defined, click in the Units box to program the engineering units to be displayed on the graph. Up to 5 alphanumeric characters may be typed in this box (e.g. PSIG or GPM, etc.).
• After all the data is entered and you are satisfied with the template, click on File at the top left side of the dialog box window.
• Choose one of the available options:
• Open: Retrieves a previously stored template.
• Save: Saves the current template you just created for future use.
• Print: Prints a copy of the scale and unit programming window as seen on the screen.

Creating Scales for Connected Loggers

• Connect the Simple Logger® to the computer’s serial port for downloading.

• See main manual for downloading instructions.

• Once the proper port is selected, data will appear in the update box at the top right hand side of the screen. This is an indication that the software has made connection to the logger. The Scale command will also appear on the task bar if the logger detected allows scale and engineering unit programming.

• A screen similar to Figure 5 will appear. The left side of the screen provides the scale and unit programming, while the right side displays the profile of the programmed scale in relationship to the actual input to the logger.

• The operator may set the scale by programming as few as two points, the low end and the high end, or by entering as many points as necessary to define the scale up to 17 points for the 4-20 mA logger and up to 11 points for the DC voltage loggers. The points entered do not have to be linear but should be an accurate representation of the relationship of the DC signal to the scale points.

• To enter a scale value in any of the slots, click on the slot and type in a number up to 5 characters. The minus sign and decimal point may be used as valid characters (e.g. -25.4 would be a valid 5-character number).

• Once the scale is defined, click in the Unit box to program the engineering units to be displayed on the graph. Up to 5 alphanumeric characters may be typed in this box.

• Once you have entered the correct scale and unit data, click on OK to proceed. The screen in Figure 6 will appear giving you the opportunity to save the entered data for future use. Click on Yes to save the data or No to bypass saving the data and use one time only.

• If you click Yes, a dialog box will open similar to Figure 7 where you can type in the name (up to 8 characters) you wish to use for the file.

• Click on OK to save the file and plot the graph with the new scale and unit data or click on Cancel to discard it and return to the scale and unit programming screen.

MAINTENANCE

Under normal conditions, the battery will last up to a year of continuous recording unless the logger is restarted very frequently.
In the OFF mode, the logger puts almost no load on the battery. Use the OFF mode when the logger is not in use. Replace the battery once a year in normal use.
If the logger will be used at temperatures below 32°F (0°C) or is frequently turned on and off, replace the battery every six to nine months.

1. Make sure your logger is turned off (no blinking light) and all inputs are disconnected.
2. Turn the logger upside down. Remove the four Phillips head screws from the base plate, then take off the base plate.
3. Locate the two-wire (red/black) battery connector and attach the 9V battery to it. Make sure that you observe polarity by lining up the battery posts to the proper terminals on the connector.
4. Once the connector is plugged onto the battery, insert the battery into the holding clip on the circuit board.
5. If the unit is not in record mode after installing the new battery, disconnect it and press the button twice then reinstall the battery.
6. Reattach the base plate using the four screws removed in Step 2. Your logger is now recording (LED blinking). Press the PRESS button for five seconds to stop the instrument.

NOTE: For long-term storage, remove the battery to prevent discharge effects.

Cleaning
The body of the logger should be cleaned with a cloth moistened with soapy water. Rinse with a cloth moistened with clean water. Do not use solvent.

APPENDIX B
Time-Extension Recording (TXR™)

• Time extension recording is an automatic process that updates the sample rate and the number of stored data points based on the length of the recording. The maximum number of stored data points is 8192.
• When the data logger starts a new recording session, it does so at its fastest sample rate of 4096 points per hour (0.88 seconds per point). The Simple Loggers® can record at this rate for two hours. If the recording session continues beyond two hours, the time extension recording technique becomes active.
• Beginning with the sample, after the completion of two hours of recording, the logger continues recording by selectively overwriting previously stored data. The Simple Logger® also halves its sample rate to 2048/hr (1.76 seconds per point) for the new stored values to be compatible with the previously recorded values.
• Recording continues for the next two hours at this new rate until the remaining 4096 storage points are filled.

• The time extension recording process of selectively overwriting previously stored data and halving the sample rate for new stored data continues every time the memory fills up. Table B-2 shows the relationship between recording time and sample rate for the data logger using this technique.

Sample Rate per hr.| Seconds Per Sample| Total Recording Time (hrs)| Total Recording Time (days)
---|---|---|---
4096| 0.88| 2| 0.083
2048| 1.76| 4| 0.167
1024| 3.52| 8| 0.333
512| 7.04| 16| 0.667
256| 14.08| 32| 1.333
128| 28.16| 64| 2.667
64| 56.32| 128| 5.333
32| 112.64| 256| 10.667
16| 225.28| 512| 21.333
8| 450.56| 1024| 42.667
4| 901.12| 2048| 85.333
2| 1802.24| 4096| 170.667
1| 3604.48| 8192| 341.333

Table B-2 – Sample Rate vs Recording Time

• Recording continues in this manner until the battery wears out or recording is stopped. For convenience in data analysis, the recording interval takes on values of fifteen minutes, one-half hour, one hour and so on.
• Like automatic scaling, time extension recording is practically invisible to the user. For best results, set the logger to standby mode when the measurement is completed, both to avoid including unwanted information in the plot, and to provide maximum resolution for the period of interest.
