Section 7. Measurement Instructions
Note that the execution time for an instruction may vary. For instance, it will
take longer to execute instructions when the datalogger is communicating with
another device.
PanelTemp (Dest, Integ)
This instruction measures the datalogger’s panel temperature, giving the result
in °C.
Parameter
& Data Type
Enter
Dest
Variable
The Variable in which to store the results of the instruction.
Integ The time spent on integration in microseconds for each of the channels
measured.
Constant Entry
Integration
250
250 µS
_60Hz or 16667
16,667 µS (reject 60 Hz noise)
_50 Hz or 20000
20,000 µS (reject 50 Hz noise)
This instruction must NOT be placed inside a conditional
statement when running in pipeline mode.
NOTE
7.7 Digital I/O
CheckPort (Port)
CheckPort is a function that returns the status of a control port. CheckPort
returns True (-1) if the specified control port is high or False (0) if the control
port is low. CheckPort can be used on the right side of an expression (e.g.,
Variable = CheckPort (Port)) or as an expression.
CheckPort has only one parameter, Port, the number of the port (1-8) to check.
The value returned may not be valid if using the control
port as a serial port or as a pulse counting port.
CAUTION
PeriodAvg (Dest, Reps, Range, SEChan, Threshold, Option, Cycles,
Timeout, Mult, Offset)
This instruction measures the period of a signal on any single-ended input
channel. The specified number of cycles are timed with a resolution of 92 ns,
making the resolution of the period measurement 92 ns divided by the number
of cycles chosen.
