”Hi value”
”Lo value”
- these parameters define the values displayed for maximum (Hi), and
minimum (Lo) voltage of
user defined range
(0-5 V, 1-5 V, 0-10 V or
2-10 V). The aforesaid parameters can be set in the range - 9999 ÷ 9999.
A negative number can be input by entering a
'–'
mark (using
[^]
,
[v]
keys
).
The value of the
“Lo value”
parameter can be higher than the value of
“Hi value”
parameter. In such a case, for an increasing value of input current the displayed
value decreases.

”Dec. point”
- position of the decimal point for results displayed in numerical form.
The following options are available:
” 0”
” 0.0”
” 0.00”
”0.000”
The position of the decimal point is selected with
[^]
,
[v]
keys.
”Upper ext.”
”Lower ext.”
- parameter defining the allowable range of input voltages
If the input voltage lies within the defined range then the appropriate
measurement result shall be displayed despite exceeding the nominal
measurement value 0-5 V, 1-5 V, 0-10 V or 2-10 V. If the input voltage
exceeds the range defined by
“Upper extension”, “Lower extension”,
a
"-
Hi
-" or "-
Lo
-" message (depending on the direction of exceeding the range)
shall be displayed instead of the measurement result in numeric form. The
“Upper extension”
and
“Lower extension”
values are defined in V with
the accuracy of 0.01 V. The
“Lower extension”
value is defined in relation
to a 1 V in the range of 0-1.99 V or 2 V voltage in the range of 0-0.99 V (this
parameter is significant only in the "1-5 V" and “2-10 V” mode). The
“Upper
extension”
value is defined in relation to a 10 V voltage in the range of
0-1.99 V.
