CS451/CS456 Submersible Pressure Transducer

4. QuickStart

A video that describes data logger programming using

Short Cut

is available

at:

www.campbellsci.

/videos/cr1000x-datalogger-getting-started-program-

part-3

Short Cut

is an easy way to program your data logger to measure the

sensor and assign data logger wiring terminals.

Short Cut

is available as a

download on

www.campbellsci.

. It is included in installations of

LoggerNet

PC200W

PC400

, or

RTDAQ

The following procedure also describes programming with

Short Cut

1. Open

Short Cut

and click

Create New Program

2. Double-click the data logger model.

3. In the

Available Sensors and Devices

box, type CS451 (1). You can also

locate the sensor in the

Sensors | Water | Level & Flow

folder. Double-

click

CS450/CS451/CS455/CS456 Pressure Transducer

(2). Water level

defaults to feet and temperature defaults to degrees Celsius. These can be

changed by clicking the

Water Level

(3) or

Temperature

(4) box and

selecting a different option. Type the correct

SDI-12 Address

(5) for the

CS451. After entering the

Properties

, click on the

Wiring

(6) tab to see

how the sensor is to be wired to the data logger.
