User manual for regulated current source SZP-73
Functions of buttons when editing numeric and switching parameters:
While editing numeric parameter:
•
change of current (flashing) digit
•
slide change of value (acceleration, deceleration, direction change)
While editing switch parameter - selection of switch parameter.
If numerical parameter is being edited, a short press of
[ENTER]
button
change edited position. A long press of
[ENTER]
button (at lest 2 sec.)
causes of display a
”SEt?”
ask, which allow user to make sure if change of
the parameter value is correct. If switch parameter is being edited, a short
press of
[ENTER]
button causes of display a
”SEt?”
ask. When
[ENTER]
button is pressed again (while
”SEt?”
is displayed) the new value of the
parameter is stored in EEPROM memory.
Pressing this button operator can cancel the changes done up to now (if they
were not approved by
[ENTER]
button after the
”SEt?”
ask) and come back
to menu

MENU DESCRIPTION
“- - - -”
- password checking. If some password different from „
0000
” is set, then every
enter to main menu follows the entering of password. If entered password is
correct then first menu position will be displayed else warning ”
Err
”, and unit
returns to current source mode.
Due to problem with direct displaying of “
m
” letter, it is exchanged with special sign
“ “. Independently in user manual letter „
m
” is used to make it more readable
(example:
“modE”
).
7.3.1.
“OUtL”
parameter
This parameter defines lower border of recalculated current value, causing generation
4mA of output current. This parameter can be set to any value from range -999 ÷ 9999 (plus
decimal point).
7.3.2.
“OUtH”
parameter
This parameter defines upper border of recalculated current value, causing generation
20mA of output current. This parameter can be set to any value from range -999 ÷ 9999 (plus
decimal point).
The
”OUtL”
value can be greater than
”OutH”
value. In such case current output
range is switched upside down. It means that while displayed (recalculated) value
is increased, output current decreases.
7.3.3.
“Pnt”
parameter
Decimal point position
. It can be set to:
“ 0”
,
“ 0.0”
,
“ 0.00”
,
“0.000”
Decimal point position is changed by
[^]
,
[v]
buttons.
