TDR100

Example 2, Measure and Record; Analog Measurements, Volumetric Water

Content, Electrical Conductivity, and Capture a Waveform

A CS605 or CS610 probe is connected to Channel #3 of a Level #1 SDMX50

Multiplexer. A cable length of 9.5 meters was determined using PCTDR. The

La/L value is converted to volumetric water content using the Topp’s

calibration (Section 7). The program is executed every one minute while

Flag 1 is High. The user can set Flag 1 high or low to control when data are

stored. The array id, time, analog measurements, volumetric water content are

output to Final Storage once a minute.

*Table 1 Program

01: 60 Execution Interval (seconds)

;The following P91 instruction allows the user to control when measurements are made and stored.

;When Flag 1 is low program execution jumps to the end of the table and no data acquisition will

occur.

;Flag 1 is a user flag and must be set by the user. This is done from the connect screen in PC208W

or LoggerNet;or using the keyboard display with the *6 Mode D command. The default status for

Flags 1 is low.

;This instruction can be removed if the user does not want to manually trigger data acquisition.

1: If Flag/Port (P91)

1: 21 Do if Flag 1 is Low

2: 0 Go to end of Program Table

;Measure the datalogger power supply voltage:

2: Batt Voltage (P10)

1: 1 Loc [ Bat_Volt ]

;Measure the internal temperature of the datalogger:

3: Internal Temperature (P17)

1: 2 Loc [ DL_Temp ]

;Set port 5 high to switch ON "Switched 12V" power from the datalogger to power the TDR100.

4: Do (P86)

1: 45 Set Port 5 High
