Temperature Logger
The SmartReader Plus 4 is a logger that can monitor low gauge and differential pressures and
temperature.
1.7.1

Description

The SmartReader Plus 4 LPD is a two-channel data logger with internal pressure and
temperature sensors. The low-pressure sensor is built into the logger and is capable of
measuring low gauge and differential pressure.
1.7.2

Setup

The logger is shipped with two pieces of permanent protective tubing covering the external
ports. Never remove these tubes; attach extension tubes to this permanent protective tubing.
1. Connect the interface cable to the logger and to the serial port of your computer.
2. Run TrendReader to communicate with the logger. (The logger has been shipped
calibrated and with the appropriate equation. See below for pressure ranges and their
equation numbers.)
3. In the SmartReader Plus window, check that the values in the logger match those on the
calibration card.
4. Select the sample rate you require.
NOTE: In Realtime mode the logger reads and displays the pressure every eight
seconds. If the sample rate is greater than eight seconds, the average value for
the sample interval is stored (based on eight-second readings). (Refer to the
