How to Adjust Deployment Scenario Settings
Use the fields in the Deployment Scenario section to estimate the recording
schedule for the currently open program in the calendar view.
1. Load a sample program or a custom program.
2. In the Deployment Scenario section, choose the target Song Meter device
for this program:
■ SM3 : This model has two built-in internal microphones.
■ SM3BAT : This model supports ultrasonic sample rates and zero
crossing recording. It does not have built-in acoustic microphones.
3. In the Start fields enter the date and time in the following format:
DD/MM/YYYY HH:MM:SS
4. In the series of four (4) fields labeled A , B , C , and D , select the estimated
capacity of the memory card you plan to insert in each slot.
5. In the Mic 0 field, select the type of microphone you plan to use on the
channel 0 (left). For mono, specify just one microphone. If you do not select a
microphone, errors will be shown in the program.
Selecting the proper
microphone also makes the battery longevity estimate more accurate as the
external microphones do use more power.
6. In the Mic 1 field, select the microphone you plan to use on channel 1 (right).
7. In the Trig Ratio (%) field, indicate the percentage of time during recording
periods that a given microphone will be triggered. This only applies to
triggered recordings. The default value of 10% is a good estimate for bat
recordings. Adjust as needed based on past experience with your specific
recording conditions.
8. In the Power (Wh) field, enter the anticipated battery energy to be used for
recordings made from this program in watt-hours. Wh can be calculated by
multiplying the battery capacity in amp hours (divide by 1000 if given in
milliamp hours) by the total voltage of the batteries. Total voltage is the sum
of all the battery cells. For example, 4 internal alkaline D size batteries at 1.5 V
each with a capacity of 12,000 milliamp hours would be 12,000 divided by
1,000 = 12 amp hours. And 1.5 V times 4 batteries = 6 V. Multiplying 6 V
times 12 amp hours gives us 72 Wh.
NOTE: Using a 12V external battery is about 85% efficient as compared to 6V. Multiply
your calculated watt-hours by 0.85 before entering into the configurator to
appropriately derate the power for more accurate longevity calculations.
9. Examine the recording calendar and make any adjustments.
10. Click the File menu and choose Save . Save the resulting .PGM file to a
memory card and insert in slot A of the SM3BAT recorder.
