7.3. MENU DESCRIPTION

Password checking. If the password is different from "0000", then the number
(password must be entered every to enter main menu)every enter to main menu
"- - - -" follows the entering of password. If entered password is correct then first menu
position will be displayed other wise the 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 "
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.
first threshold of the relay (range -999 ÷ 9999). Negative values can be input by
"SEtP"
selecting a "-" sign on first digit (to change value use [^] and [v] buttons).
Threshold is the median value of relay hysteresis.

Threshold is the median value of relay hysteresis.
- hysteresis of relay (range 0 ÷ 999). Full hysteresis of the relay is equal to 2x "HYSt"
"HYSt" parameter. The relay state can change when an input signal is out of threshold-
hysteresis to threshold+hysteresis zone.
Presented parameters should be set to ensure that "SEtP" + "HYSt" , "SEt2" + "HYSt" , "SEtP" -
"HYSt" or "SEt2" - "HYSt" does not exceed the measure range. Additionally, in two threshold mode
("modE"= „in" or „out"), the hysteresis for both thresholds must not cover each other (in other case
relay can't change his state).
