• Measuring range
"Lo C"; "Hi C"
These parameters describe the values displayed for minimum and maximum input current.
For example, if input type is set to 4-20 mA “Lo C” parameter defines the value displayed
when input current is equal 4 mA, and “Hi C” parameter defines the value displayed for 20
mA of input current. Available range for these parameters: -999 ÷ 9999.
•
Decimal point position "Pnt"
The unit enables variable setting of the decimal point position.
For example 4 mA input current will be shown in the display as follows:
“0”
(400)
“0.0”
(40.0)
“0.00”
(4.00)
“0.000”
(0.400)
0.0
100.0
(0 ... 100 %, where
the decimal point
position is set to 0.0)
15.00
65.00
(15 ... 65 hl, where
the decimal point po-
sition is set to 0.00)
If the measurement value do not exceeds permissible measurement range but displayed value
exceeds range -999 ÷ 9999, the warning
″
-Ov-
″
is displayed rather than the calculated result.
• Extended measuring range
"Lo r"; "Hi r"
the expansion of nominal range in percent. They determine the permissible range from
minimum to maximum (
“Lo r”
a
“Hi r”
).
“Lo r”
determines lower border of the permissible range. Lower border is calculated due
to expression: I
min
= 4 mA - 4 mA × “Lo r” %. The
“Lo r”
value can be set from 0 to 99.9%.
“Hi r”
determines the upper border of the permissible range. Upper border is calculated due
to expression: I
max
= 20 mA + 20 mA ×
“Hi r”
%. The value of
“Hi r”
can be set from 0 to 19.9%
