must be connected to the data logger.
Making External Connections
If you are using your SmartReader Plus data logger to monitor external modules, sensors, or
circuitry, make sure the connections are tight. Also, make sure the terminal block is snapped
securely into the logger.
For permanent applications, wiring connections can first be made to the logger's removable
terminal block. The terminal block can then be attached (with glue for example) to a
permanent fixture. When it comes time to analyze data, the logger can simply be unplugged
from the terminal block and brought back to your computer. After backing up the data, the
logger can be returned and plugged back into the terminal block. Extra terminal blocks are
available from your sales representative. When unplugging the terminal block from your
logger, use care to pull it straight out so as not to break the plastic casing.
Enable Channels
Always make sure that you have enabled and verified the correct channels for your
application. This is very important as it can be distressing to find out later that the information
you hoped to collect was from an inactive channel. You can selectively enable additional
channels in your SmartReader Plus as required. However, in order to avoid using logger
memory unnecessarily, disable any channels which are not required.
Clear Memory
Before starting a logging session, clear the logger's memory. This will help to keep the
collected files smaller as well as decrease the time needed to backup the logger later. Note
that clearing the memory is automatic if you save setup changes (for example, assign different
equations, change sample rate, etc.).
Test
You can directly read the values that your SmartReader Plus data logger is sensing using the
Realtime capability of TrendReader software. This test gives you the opportunity to check
your logger setup and make any necessary changes before starting the logging session.
Label
If you are working with more than one data logger, label each logger, identifying the task and
location before you distribute them throughout a building or system. To do this, you can simply
use a shipping tag. Later, when you retrieve them to graph their data, you will know what each
graph refers to.
Mounting
Use the magnetic backing to conveniently mount your logger on metal surfaces like ductwork
or electrical control cabinets. If you are concerned about theft, lock your logger to a
permanent fixture using the locking tab or take advantage of its small size and hide it
completely out of view. Because SmartReader Plus loggers are so light, you can use special
mounting fasteners like Velcro® to attach them to almost any surface. Make sure your
logger's mounting method will last the full length of your logging session.
Do not rely on the logger's magnetic strip for adhesion if the mounting surface is uneven,
unstable or above 65°C (150°F).
