Menu Options
Input Default: mV
Allows the input type and range to be defined. There are 12 ranges
for temperature measurement available. When a thermosensor range is
selected, ie. J, K, t, r, S, n or RTD, the instrument will automatically set
the appropriate scaling in
o
C.
Engineering Units Default: Eng
Allows the user to define the units of measurement to be displayed
in
o
C,
o
F and Eng (linear engineering units).
Decimal Position Default: 1
Defines the position of the decimal point for the display; 0 or 1 for
thermocouples/RTD and 0 to 3 for process inputs.
High and Low Display Values Default: Low = 000.0, high = 100.0
The low display value LdSP is used for scaling purposes
when combined with the other scaling parameters L-iP, HdSP, and H-iP.
These 4 parameters can scale the measured input to any engineering units
as long as the relationship between the displayed units is linear. LdSP is
used to define the value to be displayed for an input defined by L-iP.
HdSP is used to define the value to be displayed for an input defined by
H-iP.
High and Low Input Values
Correspond to the signal output values from the sensor
which will cause the instrument to display the values set as LdSP and
HdSP. L-iP and H-iP can be input in mV, V, mA etc.
There are 2 methods of setting the low and high input
values, either by manually entering a signal value using the VAL option or
by sampling the sensor output using the rEAd option. Values entered
manually are entered in the same way as other numeric values (see
Editing a Value page 11). The value to be entered will usually be
supplied with the data accompanying your sensor. However, if it is not
available, the output from the sensor may be rEAd from an external
inPt
