SmartReader 8 Eight-Channel Temperature Logger

The SmartReader 8 is a versatile logger for recording temperatures in a wide range of

environmental and industrial applications. It can record up to eight temperature channels

simultaneously.

Figure 8-1: SmartReader 8

1.10.1 Description

The SmartReader 8 has seven external temperature channels (for remote temperature

probes) and one internal thermistor sensor.

1.10.2 Setup and Use

The following procedure will help you prepare your SmartReader 8 for your temperature

monitoring applications.

1. Setup and activate the channels you intend to monitor using TrendReader software.

Disable any channels you are not going to use to conserve memory.

2. If you are using external channels, make sure to use thermistor sensors appropriate for

the measurements you want to take (for assistance, please refer to Appendix C

Thermistor Temperature Probes). Also, confirm that the equation number you are using

for each of your probes is correct.

3. To connect remote temperature probes (two-wire), simply wire one lead into a channel

input (labeled 1 to 7) and the other into a terminal marked Common. It does not matter

which lead goes to which terminal. You can connect more than one thermistor probe to

the same Common terminal. For example, Figure 8-2 shows two external probes

connected to channels 2 and 3 sharing the same Common terminal. If you are using a

thermistor probe with shielded cable, terminate the shield wire by connecting it to any

Common terminal.
