User manual - METER PDU-4x0-W
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 measurement mode.
Due to problem with direct displaying of “
m
” and “
K
” letters, they are exchanged
with special signs “ “ for “m” and “ " for K respectively. However, in user manual
letters „
m
” and “
K
” are used to make it more readable (example:
“modE”, “tc K”
).
7.3.1.
“rEL1” menu
This menu allows to configure the operation mode of relays and LEDs marked „
R
” (e.g. „
R1
”).
If there are few relay outputs available, then every output has its own configuration menu
(e.g. menu „
rEL2
” for relay (LED) „
R2
”). Principle of the relays operation is described in
paragraph
CONTROL OF THE RELAY OUTPUTS
.
•
The relay outputs and LEDs (named
R
) can be controlled depend on both - the
current value and the peak value (when peak detection is active) of the input
signal.
•
If device is not equipped with one or more relay outputs, menus refer to this
relays are available, but apply to LED indicators only. In such case LEDs
indicates exceeding of particular thresholds.
“SEtP”
- first threshold of the relay (range -999 ÷ 9999). Negative values can be input by
selecting a “-” sign on first digit (to change value use
[^]
and
[v]
buttons).
Threshold is the medium value of relay hysteresis.
“SEt2”
- second threshold of the relay (range -999 ÷ 9999). Negative values can be input
by selecting a “-” sign on first digit ( to change value use
[^]
and
[v]
buttons). This
