1. Turn on an AM radio and tune it to 455 kHz (the low end of the AM band).
2. Use the AM radio to listen to the tone of the transmitter. Scan the transmitter with a magnet approximately one inch from the transmitter to change the operating mode to battery monitoring mode. Most transmitters have the following sequence of modes: off, on, battery monitor mode. Refer to the transmitter sterile package for information about the sequence of modes.
3. If you are not sure if the transmitter is in the battery monitor mode, repeat step 2 and compare the different tones until you are sure you hear a low tone. Repeat steps 2 and 3 for each transmitter to be monitored.
4. Place the transmitter on its associated receiver.
5. From the Acquisition program, open the Configuration module and configure each transmitter on a receiver. Refer to Beginning the Configuration Process for more information.
6. Highlight the animal ID in the Acquisition window, right click and choose Start Sampling - Continuous.... The Start Continuous Sampling window appears.
7. Select Diagnostic Trace and select the Settings... button to display the Diagnostic Trace Settings window .
8. Place a check mark in the Enabled column for Battery Life. Remove all other check marks in the Enabled column by clicking on them.
9. Change the Upper Limit for Battery life to 15 by clicking in the appropriate cell.
10. Set the graph length to 10 seconds and select OK to return to the Continuous Sampling window.
11. Select OK to display the Real-Time Graphs window that contains the battery life signal tracing window.
If there are more than 14 days of battery life remaining, an alarm window appears indicating the battery is OK and a complete 10 second waveform will not be seen in the Battery Life trace window. Continue to Step 15.
A complete 10 second waveform in the Battery Life trace window means there are less than 14 days remaining. Continue to Step 12.
If a waveform does not appear in the Battery Life trace window and the battery OK message was not displayed, check the following:
- Is the transmitter in Battery Monitor mode? Refer to Step 2.
- Is the Y axis scale set correctly? Refer to Steps 7-9.
- Is the word Stopped flashing in the title bar of the Real-Time Graphs window or the Battery Life trace window?
- Is the animal icon in the Acquisition window blinking and never turning green?
Answering yes to any of the last three questions indicates a dead battery.
12. If a waveform trace is displayed, select Data - Pause after tracing the signal for more than 5 seconds to freeze the battery life waveform.
13. Click on the Zoom icon (looks like a magnifying glass) located on the toolbar of the Real-Time Graphs window. A Static Graphs window will appear.
14. Select View - Tracking to change the mouse pointer from an arrow to a + (Clicking on the waveform trace with the left mouse button, and dragging it to another location on the window while holding down the left mouse button will allow you to zoom in on the waveform trace).
15. Place the pointer on the horizontal waveform line extending across the display from the Y axis. The X and Y axis coordinate values are displayed on the status bar located at the bottom of the Static Graphs window and change according to the location of the pointer on the graph. The Y value indicates the number of days of battery life remaining for the transmitter. Record the number of battery life days remaining on the lab sheet for this Animal ID.
16. Click the X located in the upper right hand corner of the Static Graphs window to close it and return to the Real-Time Graphs window.
17. Click the X located in the upper right hand corner of the Real-Time Graphs window. A message will appear stating that by closing this window you will stop all save and trace sampling. Select Yes to return to the Acquisition window.
18. Repeat Steps 2-17 for each transmitter.
12. The battery monitor mode has a lower tone than the On mode.
13. The TA11-CTA-D70 and TA10-TA-D70 have 3 modes in the following order: Off, reference mode and On. The reference mode is for factory use only and does not measure battery life. These transmitters cannot record temperature in reference mode
14. To monitor the battery life of a TL11M3-D70-PCTP, it must be configured as a D70-PCP for the battery monitor mode to be accessible to the Dataquest A.R.T. software.
15. Plan to perform any end-of-study checks or validations within the indicated remaining battery life. Beyond this time, the transmitter may cease to function or may provide inaccurate data.
