Switch parameters (“LIST” type)
Switch parameters can be described as a sets of values (a lists) out of which only one of
the options available on the list can be selected for the given parameter. Options of switching
parameter are selected using
[^]
,
[v]
keys.
Short pressing of
[ENTER]
causes in displaying of the acknowledge question (
“SEt?”
).
If
key
[ENTER]
is pressed again, the changes are accepted, stored in EEPROM end the edition
process finished. Pressing the key
[ESC]
after
“SEt?”
causes in cancelling of made changes
and returning to menu.
Functions of buttons when editing numeric and switching parameters:
While editing numeric parameter - change of current (flashing) digit.
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

- 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”
letter, it is exchanged with special sign
“
”
. Independently in user manual letter

is used to make it more readable
(example:
“modE”
).

“rEL” menu
This menu allows to configure the operation mode of relay and LED marked
“R”
.
Principle of the relays operation is described in paragraph
CONTROL OF THE RELAY
OUTPUTS
.
The relay output and LED (named
R
) can be controlled depend on both - the current
value and the peak value (when peak detection is active) of the input signal.
“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.
