CS616 and CS625 Water Content Reflectometers SE Chan: Enter the single-ended analog channel where the sensor's green wire is connected. When Reps is greater than 1, this entry is the channel for the first CS616. Port: Enter an integer to specify the control port that will be used to enable the CS616 sensor. For the CR510, only C1 can be used to enable a CS616. Code Control Port Option X X specifies the first control port that will be used. Subsequent repetitions will be enabled with the next sequential control port. Control port 1 follows control port 8 in a sequence. 1X All repetitions will be enabled with a single specified control port. Simultaneously enabling several CS616s can result in exceeding power supply capacity. Loc: Enter the input location that will store the period measurement. The period output is in microseconds. An Input Location is a place in the datalogger's memory where a measurement is temporarily stored until it is used in intermediate storage, output, or overwritten. An input location is reserved for each measurement in the datalogger program. Additional locations can be created by the user. Mult: A factor that the input location value is multiplied by. Enter a 1 for probe output period in microseconds. A multiplier is often used for calibration or to convert the input location value to different units. Offset: A constant that is added to the input location value. An offset of 0 has no effect on the input location value. An offset is often used for calibration or to convert the data to different units. With a multiplier of 1 and an offset of 0, P138 returns the period in microseconds. 6.4.4.2 Using Edlog Instruction 27 (Period Averaging) See Section 6.4.5.2, CS616 Sample Edlog Program 2, for example on using Instruction 27. 1: Period Average (SE) (P27) 1: 1 Reps 2: 00 Range Option 3: 00 SE Channel 4: 0000 No. of Cycles 5: 0000 Timeout (units = 0.01 seconds) 6: 0000 Loc 7: 1.0 Mult 8: 0.0 Offset 14

CS616 and CS625 Water Content Reflectometers
SE Chan
: Enter the single-ended analog channel where the sensor’s green wire
is connected.
When Reps is greater than 1, this entry is the channel for the first
CS616.
Port
: Enter an integer to specify the control port that will be used to enable the
CS616 sensor.
For the CR510, only C1 can be used to enable a CS616.
Code
Control Port Option
X
X specifies the first control port that will be used. Subsequent
repetitions will be enabled with the next sequential control port.
Control port 1 follows control port 8 in a sequence.
1X
All repetitions will be enabled with a single specified control port.
Simultaneously enabling several CS616s can result in exceeding
power supply capacity.
Loc
: Enter the input location that will store the period measurement. The
period output is in microseconds.
An Input Location is a place in the datalogger's memory where a measurement
is temporarily stored until it is used in intermediate storage, output, or
overwritten.
An input location is reserved for each measurement in the
datalogger program.
Additional locations can be created by the user.
Mult
: A factor that the input location value is multiplied by.
Enter a 1 for
probe output period in microseconds.
A multiplier is often used for calibration or to convert the input location value
to different units.
Offset
: A constant that is added to the input location value.
An offset of 0 has
no effect on the input location value.
An offset is often used for calibration or to convert the data to different units.
With a multiplier of 1 and an offset of 0, P138 returns the period in
microseconds.
