The “input” menu selects the input signal range. Options are :

Ratiometric signal

Potentiometer <5K

Potentiometer <5M

in this range the value of the poten-

tiometer must be introduced (in KOhm)

The display scaling is based on 4 parameters. These param-

eters define the two points of the straight line “signal / display”.

Input Low (“ILo”)

Signal input low

Display Low (“dLo”)

Display low

Input High (“IhI”)

Signal input high

Display High (“dhI”)

Display high

The instrument can manage up to 2 alarms. These alarms
control optional relays R1 (see section 2.1) which can be in-
stalled at slots Opt1 and Opt2. More alarms can be achieved

by installing special control modules R2 and R4. Configuration

menus for special modules are not listed in this document.

Active (ACT) -

Value “ON/OFF”. Defines if the instrument

has to manage this alarm or not. Select “OFF” for alarm not
managed.

Type (TYPE)

- Value “MAX/MIN”. Defines the behavior of the

alarm as maximum or minimum alarm. The alarms configured

as maximum are activated when the display value is equal or

higher than the setpoint. The alarms configured as maximum

are deactivated when the display is lower than the setpoint.

The alarms configured as minimum have the inverse behavior.

Setpoint (SET) -

Value from “9999” to “-1999”. Alarm set point.

Select the position for the decimal point. Modify with the LE
button and validate with the SQ button.

Hysteresis (HYST) -

Value from “0” to “9999”. Points of hyster-

esis. The hysteresis applies on the deactivation of the alarm.

Delay (DEL) -

Value from “0.0” to “99.9” seconds. Delay to be

applied to the relay activation and deactivation. Relays are
activated and deactivated X seconds after the activation /
deactivation of the alarm. The delay affects only to the relays.
The delay does not affect to the front leds.

Setpoint2 (SET2) -

Value from “-1999” to “9999”. Second

setpoint. The second setpoint allows for the creation of acti-

vation windows. If the alarm is configured as maximum with

setpoint 1000 and setpoint2 is configured at 1500, the alarm

will be activated between 1000 and 1500 and the alarm will
be deactivated when display is <1000 and >1500. Setpoint2
is affected on the same way as the setpoint with hysteresis
and delays.

Functions on this menu allow for configuration of the display.

Fixed Digits (FIX.D) -

Allows a digit to be fixed to a predefined

value (for example, least significant digit fixed to “0”). It is a

condition to fix a digit that all digits to its right are also fixed.

Value “-” shows that the digit is not fixed.

Average (AVR) -

Recursive filter applied to display. Value

from “0.0” to “99.9”. The severity of the filter increases with

the value selected. Increasing the severity of the filter makes

the display response slower.

Steps (STEP) -

Display changes on predefined steps. Values

are 1, 2, 5, 10, 20 and 50. The display is made in steps of X
counts. For example, select a step of 20 will make the display
to change in steps of 20 (1420, 1440, 1460, ...).

Left Zero (LZER) -

Value “On/Off”. Select “On” to visualize

zeros to the left.

Maximum (MAX) -

Memory of maximum display. Indicates

the maximum value of display since the last reset of the
memory. Memory is reset on the following cases : manual

reset from the Configuration Menu (Maximum), change on

the input signal (Input), modification on the scaling (Scaling),

change on the decimal point (dP), modification of the linear

ization segments, or instrument power-down.

Minimum (MIN) -

Memory of minimum display. Indicates the
