Figure 7-11: Using Voltage Channels with a Power Supply
To set up the SmartReader 7 you first disable all the input channels except for one of the 5V
channels. You set this channel with a sampling rate of 2 minutes and activate the battery
switch. That way you will minimize battery consumption and maximize memory, allowing you to
collect over forty-five days of data. It will also leave plenty of time for you to retrieve the logger
after the logging session and transfer the data to your computer.
Before heading out into the field, write a simple equation converting the 0 to 5 volt signals into
the 0 to 5" W.C. pressures. See your TrendReader software guide for information on writing
custom equations. After saving the equation to the 5V channel, you can then test the logger's
operation by viewing channel's Realtime reading using TrendReader software.
