Menu Options
Input
Default: mV
Allows the input type and range to be defined. There are 12 ranges
for 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.
Note:
Due to the limitations of a 7-segment display, the
mA
option is displayed as
na,
the
mV
option is displayed as
nu
and the
ohms
option is displayed as
ohns
.
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
