Section 7. Measurement Instructions
The back-to-back silicon diodes D1 and D2 provide ESD protection of
capacitor C and the sensor, and also limit the amplitude of large amplitude
sensor signals. These diodes clip large amplitude signals to approximately 1.4
V pk-pk which is within the recommended input signal ranges for all range
codes. Diodes D1 and D2 along with resistor R1 are recommended to limit
large amplitude sensor signals, even when dc blocking capacitor C is not used.
Sensors outputting large voltages may cause large currents to flow through
these back-to-back diodes. A current limiting resistor may be desirable to
minimize these currents in some situations.
The current flow through these clipping diodes may also induce single-ended
offset voltages if it returns into the
ground terminals. Single-ended offset
voltages of up to 2 µV/mA of current that flows into the
ground terminals
can be induced across the front panel. The back-to-back diodes can be tied
into the G ground terminals, rather than
ground terminals, if this is a
problem.
PortsConfig (Mask, Function)
The PortsConfig instruction is used to configure one or more control ports as
either input or output.
By default, ports are configured as input. The PortsConfig instruction may be
needed if a port is configured as output by a WriteIO or PortSet instruction and
then subsequently needs to function as an input.
Parameter
& Data Type
Enter
Mask
The Mask parameter is used to select which ports will be affected by this
instruction. It is a binary representation of the ports (reading from left to right,
the ports are represented as 8, 7, 6…1). If a port position is set to 1, the
datalogger configures that port. Binary numbers are entered by preceding the
number with "&B". Leading zeros can be omitted. As an example, if &B110 is
entered for this parameter, ports 3 and 2 will be configured, based on the
Function parameter.
Function
The function parameter is used to configure the port. A binary value is entered
to set each port location. 0 configures the port for input; a 1 configures the port
for output. Using the above example mask, if the Function parameter is set to
&B110, ports 3 and 2 will be configured for output (port 1 uses the code for
input, but it is not affected because of the mask).
PortGet (Dest, Port)
The PortGet function is used to read the status of one of the eight control ports.
Remarks
This instruction will read the status of the specified port and place the result in
the Dest variable.
Parameter
& Data Type
Enter
Dest
Variable
The variable in which to store the result of the instruction. A 1 is stored if the port is
high; 0 is stored if the port is low.
Port
Constant
The control port number (1-8) for which the status should be obtained.
